well guys i sold my TurboII today so im gonna start using my track car as my daily driver until my landcruiser comes in... but neways the other day i decide to crank it up since it hasnt been turned on in a while when i go to pop the hood i see the battery fell over (no battery tie down) and well the postive side of the battery fell on the front cover of the motor and grounded out im guessing theres no power running to anything at all im guessing the battery is completely toast.... ill give you guys a heads up more tmw that im gonna work on it ... but what do you guys think i should be looking for????
Thanks

Hopefully you just fried the battery. Frankly, with a direct short, I'm very surprised it didn't melt down and set the car on fire.

But I have seen batteries shorted to ground that have semi-fried parts of the car. Strange ECU problems result.

 

yea actually aaron i was wondering the same i mean i went over the wires not a single one was melted the battery already was kinda messed up (was leaking liquid every now and then) and well i went over the fuses and nothing you think the computer could be messed up???

Could be...

 

ok ill give you heads up right now im gonna go connect the battery charger directly to the cables and see what it gives me ill brb in a few min....
TwEaK

 

That's not smart. Battery chargers output a pulsing DC. Very dirty, and not good for any of the electronics.

Swap in a different battery.

 

i had my 86 n/a all stock runing fine
sat for a month, put new brakes, bled the system, took out the filter and put on a cone, tightened everything back on, checked everything and now when i start it the car revs to 3 grand then shuts off
and ive tried reving it while it does that
the battery is low so i was using a jump pack
and i didnt think untill now if that could be part of the problem
just lookin for some possible reasons

 

ummmmm Michelob go make your own thread pls dont waste mine....

aaron i put in another battery from my brothers car its an optima red top battery and i got 0 power i have ALL lights work on the car but theres no starter or anything to that affect i have a friend lending me a computer to see if thats the prob but im guessing i fried the computer....

You're..track car...had no battery tie down? How did you run a track with no tie-down? And using a battery that leaks fluid, that you KNEW about, well that doesn't sound too smart :O. Grounding out on the front cover, couldn't that have shorted all metal things touching the front cover at all? Aka..starter..lol..

 

lol i havent tracked the car yet its just going into production now but i just started a new job and i need a car to get around that gets decent gas milage... sad to say this car gets awesome gas milage due to the fact that it doesnt weigh **** and its n/a the battery leaked because i had dropped it but it didnt crack it was leaking only when i would lean it over to the side ( the plastic cover piece on the top) it would leak threw it didnt cause a problem when i was driving it for a bit...

neways i went over the harness today and nothing seems to be burnt i went over the fuses and no fuses are blown im gonna swap out a new computer when i get the chance and ill let you guys know what happens..

I hope you can track down the problem TwEaK. I wouldnt want you to miss a meet here in my neck of the woods. But from what you say....Do the warning lights go off when you try to start the car? This may be stupid of me to ask, as this is the first 5-speed vehicle that ive owned, but maybe the sensor at the clutch got fried....but as you said, if youve got soemone with a computer to check it for you then go for it.

 

hehe Rotaryexp im begging my dad to go with me but all depends on work and cash =) no warning lights or anything turn on just headlights/brake lights/interior lights/dash lights/nighttime running lights.... ill see i might litterally just make myself a new harness and go from there but well see..... ill give you a heads up tmw when i get out of work if i can get the stuff i need to get it running again....

Yeah I understand the money bit, ive been scavenging as much as I can to keep this beast on the road every week. One thing goes over the weekend just in time to be fixed lol. But I guess the puter check will reveal all if it works. And yeah bring along the dad, get him into what you love and maybe you will have parental support for the habit.....ive had no support so far myself

 

try to push start it, thats what i did ......

 

If the starter isn't firing, then I doubt it's the ECU. Check the anti theft, the stater cut relay, etc. Check for 12V at the ignition switch. Go over the wiring diagram and check for 12V where you expect it.

Who knows what you fried....

 

errrr.... dam i just started my new job so i dont get out of work till 7 and by that time suns already going down... ill have to start over the weekend right now im gonna try to get the alternator and the mastery cylinder that is shot... but mayb ill pull start it how it is and see how that does...

TwEaK

 

and my dad might go he has a 3rd gen 3 rotor but doubt hes gonna do a long drive in that thing...
TwEaK

 

cmon guys ne ideas?????
TwEaK

 

What about the suggestions I have posted? You need to trace the 12V to the starter solenoid, key switch and ECU.

 

i just got a new job at a mechanic shop so my boss told me hed let me bring in the car to work on it at the shop and hed help me out with any problems... funny thing is ill still be getting paid to work on my 7 ;D ill give you updates on saturday most likely
TwEaK

 

Congrats TwEaK, getting paid to work on yoru own car is brilliance at work. But as Aaron said, check the voltage and other such things and one may be able to find a easy and cheap cure, hopefully its nothing majorly expensive. *Moves away grumbling about $600 wheel hubs*

 

lol thanks RotaryExp i worked on the car a bit today my mechanic was more than willing to put his work aside to help me out i had to trailer it to the shop only bad thing about today was trying to make a u turn with a almost 20 foot long trailer i kinda side swiped my boss's car =/ but he didnt really car he just wants me to pay for the light that broke.... but neways i tried to diagnose shurly enough again when i popped the hood after getting it down the battery had fallen again and was leaning on the motor so first thing tmw ill be getting a battery tie down.... i did get to check some power i am getting a 12v power to the ignition so now i gotta see if its going to the start you said correct??? aaron?? neways also how do i check if im getting 12v to the ecu??? anyone got a diagram of which wire is which for the ecu????
Thanks
TwEaK

 

Download the online FSM. Just the Fuel section. There is a section called Control Unit. It tells you what voltage to expect at each pin of the ECU.

 

The power arrives at the ignition sw on a pure black wire.

When you go to start, it leaves the ignition sw on a Black/Red wire and goes to the interlock sw on the very top of the clutch pedal. It leaves the interlock sw on a Black/Green wire and goes to the Starter Cut Relay near the Main Relay. It leaves the Starter Cut Relay on a Black/White wire and arrives at the starter solenoid.

On some early cars that did not have a interlock sw,
OR cars without Theft Protection, the path is different .

No theft protection means there is no Starter Cut Relay. In its place is a connector with a single jumper wire in it. The jumper connector is BLUE. You can't miss it. It will be located under or near the trail coil assy.

If you want. you can pull that Blue jumper connector off the plug and then jumper 12v from the battery to the black/white wire in the connector. The starter will turn over and the car will move in a fwd direction if it's in gear and run your feet over. Yell real loud for help.

 

rofl thanks hailers i gotta go find some battery tray today im gonna start on it on monday ill give you all a heads up..... but one last question what about my idiot gauge cluster lights not lighting up??? i checked the fuses but again havent gotten anything
Thanks
