Suicidal Tendencies - Not just a band name...

Time for an update on all things wiring in the context of Stacey.  Here's where I thought things were at when I last looked at her...

"Hopefully I can cut out the wires, tape up anything exposed, and just the indicator stalk to control the parkers (provided there's no serious damage to that circuit as well).  If that doesn't work, hopefully I can make it burn again so I can at least have a better idea as to what the next step is.  But thats for another day."

Seems that 'other day' came today, where I figured I better make some more progress.


Given how frustrating it was to figure out what was going on last time, I got around to downloading the Factory Service Manual for the car, printed off what I wanted and bound them (thanks Siemens for your office supplies =D). Very very useful, provides me me with what wires go where, into what plug with what pin number, and what colour said wires are!


This is what I kicked the day off with... it really is a depressing sight :(  Alas, I started off by sorting out the wheat from the chaff, one wrecked wire at a time, tracing it back until I knew it could be deleted or replaced, separating it from any wires that it had melted to along the way, and taping up any collateral damage that I found.  This was going swimmingly, until I got onto the 3rd wire...  Where I traced it, kept tracing it, continued tracing it... until it disappeared.


Never mind, found it!!  Running down the side of the car under the carpet... GRRRR!!!! Made even better by the fact that I could straight away see the melting... So, out comes yet more of the interior...


Can't say I don't have room to work at least!!  Trying to still see the positives I guess.


You can see the true damage to this loom if you look hard enough... there's a group of a good 9 wires that are well and truly fused together =\ and the best bit is that throughout the length of the loom, it changes which wires are fused together.  The really weird thing though, is that the wiring runs down the side of the car to the ass end, and sorts out all your lights, antenna, speakers, fuel pump etc, but the melting stops a good meter from any of that.  WTF?!?!?!?!??!?!!


And so began the sorting of the loom... wire by wire, tracing every single one, separating where necessary, and noting where they went and what they supplied... Keeping track of everything I found for future reference, and to help decide if it would be worth rewiring, or just buying a whole new loom.


My work space for all these shenanigans, with the growing collection of parts that I'm continually pulling out... I'm really not looking forward to putting them all back in hey!  So many screws, and I have no idea where they all are... oops!


Kitten guts thought that the 20 year old seat looked comfortable though :)

So what did I accomplish at the end of all this?


Where I decided to call it today after another 5 hours... tedious, painstaking, frustrating and just downright depressing...


The mud map I've been building, keeping track of what I've figured out, what I can get rid of, what I need to keep/re-wire, and everything in between.


What cancer I've cut out so far... the ruined wires, and alllllll the insulation/tape I've stripped so far... 

Where does it leave me?

Given I've properly stripped everything out, and have seen the ruined wires in their entirety, I'm going to try rewiring the loom first... I can save quite a few wires, so I don't think it's going to be worth replacing the whole loom just yet. I would more or less need to replace a dozen wires, and the ones that aren't too bad can be taped up.  I've also been able to omit quite a few wires that no longer do anything, and thats helped the situation.

The goal is that I'll rewire these lengths, try and see if I can get things working, and if not, I'm hoping that I'll be able to pinpoint the issue given that everything is now exposed.  If that doesn't work, replacing the loom will be the next step.  The frustrating thing is though, I still have absolutely no idea whats caused this.  There is nothing thats standing out that would indicate a problem, just a looooooooot of burnt, mangled wires.  For all I know, replacing the loom may not fix anything.  The bright side is I can safely say I know why the fuel gauge buggered up!  The fuel sender wire was caught up in the middle of all the melting, and it normally reads ohm-age, not a 12V source =\

Suicidal car is suicidal.

Losing, and more losing...

2 months of waiting... I finally had the time to look at Stacey after the issues that plagued me on the way home from QR at the track day... To jog your memory, my dash went up in a cloud of smoke... The parker circuit has been problematic, thought I'd fixed it, car never missed a beat the whole morning through some pretty hard track work, and then decided to act up again on the way home... Couldn't see/breath, and the fuse decided to hold on for dear life, and when it finally went, took the stereo, fuel gauge and clock with it.


After some cursing and swearing, I finally managed to get the fuse out... Um... yeh, that's not supposed to happen.  How on earth is a 10A fuse capable of deforming itself to this extent without popping?  Put in a fresh fuse with the hope that maybe it might have fixed the issue, or I'd have enough time to get a better idea of where things are going wrong, but to no avail.  Close examination revealed that the fuse is somehow still in tact... It was the wiring (down the page a bit) that went first.  WHAT THE HELL!!!  OK Stacey, time to get nekkie!!!


I started off by removing a couple of panels to see where I was at...  Wires bloody everywhere =S  Also took the opportunity to check out why the radio wasn't working in the hope of it helping my troubleshooting... turns out its getting switched with the accessories, but getting no power from the battery for some reason... found out its running through the factory loom too, so, pretty safe to assume I can throw it in with the same reason why everything else was broken.  Damn.


Finally managed to get my hand onto the wiring loom that ran to the parkers switch.  Initial signs are not looking good!


After pulling off some more things such as panels, plugs etc. I got a better look at the damage.  Time to remove all that tape to find out exactly what condition those wires were in...


Yehhhhhhh not good!!! All those wires are supposed to have a coloured protective shroud on them, instead they're just bare copper... all of them.  Oh, plus a mixture of cooked shroud and melted electrical tape smattered all around them :) 

Trying to get any access to any of the wires was incredibly cramped underneath the dash, so I decided it was time to get a bit more extreme...


After pulling out all of the panels...


I finally had the dash out.  First time I've ever pulled one out, not something I want to do again anytime soon!!  20 years of rust and dirt exposed to the atmosphere.... take that EPA :) 


Figured while I was at it, I'd have a look at the plastic that sat in front of the gauge cluster, see if I could clean it up a bit.  More on this later.


I continued stripping the wires, it just got worse and worse...  Seems I wasn't going extreme enough.


After some more swearing and cursing I finally managed to expose the wires running from the fuse box to the plug.  Time to start tracing those wires...


You've already seen the condition of the plug end of the loom, this is at the other end at the fuse box... Yep, melted here too.


And melted in the middle too =\ Great.  After working on this for the better part of 6 hours, I decided this was as good a place as any to call it for the day...  Time for a sitrep perhaps?

That loom is beyond knackered, there's no doubt about it.  And given the state of those wires over the course of the loom, chances are better than good that as the wires burnt, they have burnt through some other wires, and the whole lot has just shorted out.  I'm going to have to separate that whole loom to find out where that's happened, and tape up the damaged sections with the hope that it will fix the other issues.  

In terms of fixing the obvious one?  After some investigation, I found out the parker circuit runs 2 looms... one to the indicator stalk, that you use to turn your lights on, and the other to the fog light switch that turns on the parkers when the fog lights get turned on.  Weirdly enough, the loom that runs to the indicator stalk is fine =\ and given that I don't have any fog lights, I might as well omit that circuit altogether. Hopefully I can cut out the wires, tape up anything exposed, and just the indicator stalk to control the parkers (provided there's no serious damage to that circuit as well).  If that doesn't work, hopefully I can make it burn again so I can at least have a better idea as to what the next step is.  But thats for another day.


The only win I did have?  Managed to clean up the plastic in front of the gauge cluster... Its not perfect but its 100% on where it was... Look at the first picture here if you want the comparison.  Gotta have a win some times :)

Hopefully its not 2 months before I get to continue...

Track Day @ Lakeside/QR

Sunday the 12th of March marked my first proper session on a track.  Sure I had some time previously at the Powercruise, but this was some actual time where we were given the opportunity to actually drive, instead of being limited to 100 kph... $40 got us track time at 2 tracks (Lakeside & Queensland Raceway) including meals... little did I know just how much value for money I was getting!!!


Anyways the day started off bright and early with a pre-meet for the Gold Coast people at 5am.  Been a damn long time since I've been up this early!


Nothing like driving at the crack of dawn as the sky starts to get light... Empty freeways, a cold air full of anticipation and excitement... as hard as it is to get up its always worth it :)


Everyone had to give their cars a good blap through the Clem 7 tunnel... Pity about the speed cameras, feeling for ya Pubes!  Regardless, the sounds that we can make in that tunnel always put a smile on our face :)


It was dry when we left the tunnel, and wet when we left.  Never a good sign, and it had us concerned for a bit, but thankfully the rain stayed away for the whole day.  We had a couple of light showers come through, but nothing that affected us while we were on the track.


Waiting to get into Lakeside... I've never been to this track before, only ever heard of its existence.  So didn't really know what to expect, especially given that I was still waking up and my mind was having issues functioning...


This was our crew of cars... for some reason the song about coconuts all standing in a row comes to mind =D  Also a great shot of the impending clouds that had most of us (there were a few that were looking forward to the slippery conditions) worried. 


Lakeside is a very fun track.  Some very tricky corners, a lot of variance in conditions, and plenty of hills to keep things interesting.

We started off with breakfast, while another group had some track time.  We had what was basically a practise session, where you can take your car out and just drive.  It differs to a proper track day because its a lot less formal, there's no official rules or regulations, just a session where people can get out in whatever car they choose (everything from tuned Civics and WRXs to Rav4's and Holden Cruze's).  No helmets, no long sleeved attire, just common sense and good times :)


Unfortunately this guy got a bit excited and had a moment... 

Needless to say mate, I feel your pain!! He simply got too aggressive, cut a corner, got some wheels on the grass and lost control.  Spun a couple of times, smacking the front and the rear at the same time.  Thankfully he and his passenger are OK, but unfortunately the car isn't.

We were concerned it might have had some ramifications for our session, given that we were on after the accident happened, but all it resulted in was a comment about being careful, knowing our limits, and driving to suit the conditions.  Duly noted :)  Didn't want a repeat of history!


Waiting to get on the track, I couldn't work out if I was more excited or nervous!!  I did have to laugh, there were 2 guys from the previous session that I overheard making a comment about how they can't wait for us to clutch kick... for the uneducated, basically they couldn't wait for us to start drifting.  I wish I could've seen their faces as they ate their words... granted, the appearance of some of our cars could've definitely led to their conclusion, but to be honest, I think quite a few of us would've had them quite easily :)


Sorry, bit hard to take photos whilst driving =P and driving hard at that!!  We were given free reign to drive, and drive we did.  Had an absolute blast just pelting around, going pretty damn hard out and then some :)  Had to back it off a bit as I had some braking concerns I was mindful of (cracked brake rotors will have that effect on you) but the highlight of the whole day was having a great battle with Casey.  We ended up meeting on the track, and I'm proud to say, a race broke out.  It was genuinely wicked fun, going as hard as we dared, trying to match each other corner for corner, doing what I always wanted to do as a kid.  You could seriously not wipe the smile off of either of our faces, and it was something we talked about for the remainder of the day.

So instead of taking photos as I was too busy driving, I got a photo of all of us after our track session, talking about what can only be described as racers excuses =P trying to justify moments of poor driving or judgement, and rubbing in the moments that were amazing.  Oh and letting the cars cool down properly of course... Track time is bloody hard on any car!


Did find this classic baby down the bottom of the function room... beautiful.  

There were several other groups too that ran after we did, and I got some (average) photos of some of the other cars we got to watch.


A beautifully finished Caterham 7 (looked a lot better in person, trust me)


A formula ford kind of thing


This thing was brutal.  So quick, so much downforce that it handled like a slot car, and so damn low that across this back straight, all you could hear was its body scraping on the ground, followed by a heap of smoke that was generated from the scraping body


And another variant of some incredibly custom vehicle.  Gotta love purpose built machines!

We headed off about mid morning to continue our day at Queensland Raceway (QR).  We arrived to the sound of screeching tyres, and that could only mean one thing...


Short track was on :)  So incredibly relaxed, just guys drifting as they wanted to without having to worry about scores or doing perfect runs, it gives them opportunities to experiment.  The guy in the black car was having big issues retaining his body panels, he lost quite a few panels to the cones while we were there, and the guy in the maroon car was having quite a fun time wrecking tyres, to the extent that we saw smoking chunks of rubber flying off his wheels.


Anyways we headed back to watch the bikes that were running around QR.  They had the national track open, which is the same track that is used by the V8 super cars.  They also have shorter variants for different occasions.  Needless to say, guys on bikes are nuts!!!  So much speed, such heavy cornering, and so much at stake if you have an off.  We watched the bikes for quite a while, and while we were doing that, an F18 hornet from the nearby air force base flew over.  So awesome!!!  There was also a muscle car group at QR who had some beautiful examples of cars, including this...


A car that resembled a Lamborghini Countach, but went by a completely different name.  Something quite ridiculous that wasn't familiar at all, but it still had an absolutely amazing presence about it.


Gotta love mid mounted engines!


And so incredibly in awe of the stance of this thing at the rear.  So insane, so striking, with those insane exhaust tips, and those 345mm wide rear tyres.  345mm!!!!!!!!!!!  We all felt a bit inadequate after seeing this thing...


I'm throwing this in for my girlfriend, who is an avid Mustang fan :)  There were so many fantastic examples of muscle cars, but I'm sure we all know what tidy examples of mustangs, camaros, GTHO's and what not look like.  I love you babe <3



There was however, an absolutely bad ass Mini that deserved a photo.  This thing was an absolute rocket, and its no wonder this car was such a revolution when it entered the racing scene back in the '60s.


Couldn't pass up the opportunity to snap this beauty on the track though :)


And how can you not love that sound... *froth*


Casey pulling his stunned mullet look as we got ready to head out onto the track.


Queensland Raceway as it turns out is a very punishing track... Massively long straights, with some very tight corners, so you're accelerating very hard, then braking very hard followed by some very high speed corners.  The car is constantly under stress, whether its hard revving, hard cornering, or very hard braking.  I only managed to get 3 or 4 full speed laps in before I had to back off due to the unmistakeable smell of burnt brakes.  Did another 2 laps at half speed just to let them cool down, and then exited, only to find out pretty much everyone else had exactly the same issues =P  Its funny, most people think more power makes for quicker lap times, and by the end of it everyone was talking about how brakes need to be addressed for next time!

Stacey held up beautifully for the most part throughout the entire day.  Temperatures were never a cause for concern, tyres gripped the whole time, never had any real issues with oversteer or understeer, and the brakes (keeping in mind I was a bit gentler on them because I didn't want to aggravate the cracked rotors) did well all things considered.  The only issue I had was this...


A completely knackered tail fuse... turns out I haven't fixed the parkers issue! Whats really weird is that they were fine for the whole drive up in the dark, and for the drive from Lakeside to QR.  It was only after I left QR that they decided to do what they do best... burn themselves to death.  And I mean literally burn themselves.  Within 5 minutes of leaving QR, I had electrical smoke coming out of the steering column.  By the time I had a chance to pull over (no shoulders on the road I was on, and trucks like to rocket through the area) I had electrical smoke pouring out of the dash, coming up through the vents that you normally demist your windscreen through, out of the steering column, out from underneath the dash, and through the air vents too.  It also decided to take the fuel gauge, the stereo, the clock and the climate control with it.  Thankfully I was still able to drive her home, but it did put a bit of a dampener on the day.  However, not enough to ruin the genuinely great time I had.

I'll leave you with this... the only shot I have so far of me actually driving :)
