So here is the deal my old car got totaled from a tornado 2 weeks after my house caught on fire. So with the insurance money I could only get a car that was not running. I got everything swapped over (motor, tranny, diff, engine harness, tranny harness). The car I got was automatic, so I did a 5 speed swap.

I was having problems with power running to ground. Thinking it was my chassis harness and interior harness I swapped them out with a working set from a buddys parts car.

Motor, tranny, engine harness, and tranny harness are from a BASE model.
The new car is SE model.

After swapping out the 2 harnesses, I am having the same problem, thinking it could be my tranny harness I separate it from the chassis harness.

Forgive me if I'm all over the place but im trying to give you all the information as it comes to my whee brain.

I have found out that if i remove the alternator fuse, the test light does not come on when I try and recreate the problem.

How i am testing the ground issue :
-remove negative wire from negative terminal
-clamp test light to neg wire
-hook fat white wire (feeds power to alt fuse and the five fuses next to it) to positive on battery
-poke the test prob to negative terminal of battery
=light coming on. This is showing me I have a hot wire leading to ground somewhere, The fat white wire is the only one that has a short.

I can start the car, power seat belts do not work, i can turn the car off, when key is removed power will remain at power windows, locks, and cluster.

After turning the key to on then removing it I have tried to unplug the ignition tumbler and no change, completely removed engine harness results in no change, completely disconnect lower harness shows no change.

I have noticed both chassis harnesses i have are missing a pin at the power interface gray plug, but the engine harness has the 8 there.

I have started to disconnect components and see if there would be any change, none.


If you have any questions please let me know. I will give you any and all information I can.


Oh, now all wiring is for se manual power everything...

Thanks in advanced for all the help I may or may not receive.

To describe how aggravated I am with this car... listen to this song for a least a week.
YouTube - ‪Daft Punk - Short Circuit‬‏ (http://www.youtube.com/watch?v=TszmdpUtf0A)

This song is sure to piss off anyone as much as my car is pissing me off right now.

Yeah the tornado hit my work when i was there, put a dumpster on my car and insurance only wanted to give me 900 for my car minus a salvage fee 325 bucks and deductible of 500. Needless to say, I haggled them up to 1800 cash after deductible and salvage fee. I had to move after the fire... good thing a vol firefighter saw my house was on fire, he woke me up. the fire fighters tore up my room.

nuff about that more onto the problem at hand...
WTF is up with my alt wiring?

it sounds like the same problem you get when you try to put a 5spd trans harness in an auto chassis, the egi makes a noise, the acc lights stay on until you disconnect battery or start the car, its a weird thing, but you should just check your wiring in the trans harness to make sure nothing melted together or anything.

or for a quick idea, take out your egi relay and see if that fixes the problem(temporarily of course)

well i dont have the lower harness installed at the moment nor the engine harness.

I have found that the problem lays in two places?
1. room light circuit
2. passenger side door lock timer

With both of these things unplugged things seem to work fine. I have ground on the chassis where it needs to be. But the auto seat belts dont seem to work.

I put the fuse for room light back in place ( at driver foot panel) and everything worked great for a min or so, then poof i have power to chassis. The passenger auto seat belt even worked to open.

judging by the pictures, your in the air force? where in Arkansas are you stationed because i have a really close friend stationed down there and he said that that his base got hit by tonadoes and their skate park was lifted and thrown over the fence and a good distance aways by the interstate or something? Just curious if you knew John Havercamp a.k.a. Handlebars


and im sorry i cant be any help to your thread, but the last electrical gremlin i had, i just rewired the car and eniminated everything that wasnt needed. Seems to have fixed the issue.

Shanes14, its cool i found my problem. It has to be a component of that circuit where the "room light" fuse plugs in.

The fuse gives power to:
radio
auto seat belt control unit
auto antenna timer
head up display control unit
interior light
time control unit
A/T control unit
clock

I know it is not the clock or hud control unit because I had the cluster unplugged with the issue still being present. Nor is it A/T control unit, because the car doesnt have a/t wiring any longer. The antenna cant be it either, its not plugged in. The radio isnt plugged in, so i can rule that out. Same thing for the interior light. That only leaves "time control unit" or "auto seat belt control unit", one of these two things are sending power to ground.


theboy, you are correct. I didnt want to let that information out cause my first post made me seem kinda dumb. The skate park was moved a few yards, yes. It was quite the experience being in a tornado.
