Okay so...if it's not one thing it's another with this **** car!!!!!! I just pulled the whole transmission to replace the release bearing and the pilot bearing.....it took forever to get the stupid pilot bearing out and now finally once i think i got everything back and get excited......i connect the battery and my starter starts spinning....doesnt kick out at all just spins...and spins...and spins...no key in the ignition or anything....when i took the starter off when i started working on my car i forgot to disconnect the battery and the two cable touched together...they were off the starter though....i got everything put back how it was...there is this one tiny black wire that looks like it broke off somewhere near the starter but idk what it's for....the + and - and the little switch wires are all connected...WTF is going on!

 

Does the Black/Red wire at the starter solenoid have voltage on it? It shouldn't.

 

Yep!

 

Not good! Does the Black/Green wire at the interlock switch located on top of the clutch pedal have voltage on it? It shouldn't.

 

take a pic of your melted down starter wiring. your spade connector terminal is grounding on the positive lug somehow.

 

nothing on it is melted anywhere that i can see....i've always been able to start it without pushing in the clutch so i dont think checking that wire will do me any good :/....

 

If you by chance damaged the ignition switch then it would cause the wire I suggested you check to have voltage on it when it shouldn't if you have the relay bypassed or the alarm is not operating properly as well. This wire is before the interlock switch and not after it. The wire that is after it is the B/R wire which you already said has voltage on it so the B/R wire is getting voltage from somewhere and there are only so many possibilities.

Rather than checking the B/G wire at the interlock switch try measuring voltage at the Starter Cut relay when it comes to the Black/Blue wire, and both Black/Green wires.

 

easy, when you bolt the battery wire to the starter it is easy to misalign the tiny craptastic keyway that holds it from spinning too far and touching the spade ignition on connector, causing the starter to always spin with the battery hooked up.

 

okay....i'll check those wires...i got to head to work....the cables arent touching on the back of the starter i definately made sure of that....i'll trace the wires down tonight and see if anything has melted through and is touching....also the wires for the reverse/neutral safety and 5th gear switch broke off when i dropped the tranny...i dont have the ground wire for the transmission hooked up yet....i ran a jumper wire to it though and the starter still does it....but i imagine the ground is just for that switch....anyways thanks for all the help guys!

 

Did you by chance connect the + and - cables from the battery to the starter in reverse order?

 

i think you mean hook up the positive wire off the battery to the wrong post on the starter. which i'm sure you meant. hooking them up backwards would be impossible without having a visit from the fire dept.

 

I'm lookin at it in the morning yall...i'll let you know what a burnt asap lol

 

Well....i ran a positive wire to the starter just to make sure it was shorting out on one of the wires....well it still spun....i took the starter off and connected the regular starter wires to the terminals and it didnt spin when i connected the battery but everything else clicked on like it should...i put the starter back on and when i connect the battery it spins again....is there some ground on the transmission that has to be connected for some reason? cuz this is just really stupid!! I really dont know what to do at this point....i wouldnt think the solenoid for the starter is messed up cuz it didnt spin when the starter wasnt bolted to the tranny....i even disconnected the ground on the starter and connected the battery and some how the damn thing spins...i'm about to give up on this thing....it's my only car and it's been on jackstands for almost 2 weeks....

 

i'm guessing you had the starter off the engine when you hooked up the battery, the starter gets it's ground from it's chassis when it is bolted to the transmission so it won't spin if it is just hanging there.

just for ***** and giggles, unhook and check to see if there is voltage going to the small spade connector wire(on the engine harness side, not on the starter) without the key in the crank position. it should only show voltage when the key is in the crank position.. if it is doing that then you have a starter issue plain and simple. it is possible to spin the stud inside the starter solenoid so that it is contacting the start wire connector, meaning you will need a new starter solenoid if that is the case.

i still suggest getting some pictures of how you have it all wired up and bolted to the tranny, a picture is worth a thousand words and we are already approaching that..

 

i made a mistake when i wired up my starter when i did my drivetrain swap. had the same issue when my battery was wired back up with the spinning starter. gonna try digging for that old thread... i believe that one of the connections were grounding to the starter or something. i forgot.

after reading it, i guess i had it on the wrong side. =P you're the same? hopefully you get your issue resolved.

 

:/ well i wish that was the problem!!! I'm pretty sure it's a lot worse then that!!!! I'm pretty positive i melted something in the ignition switch! Anybody know how hard that is to do?

 

Did you disconnect the Black/Red solenoid wire and check if it had voltage to it? If you did and it did then you need to go to post #7 and follow the advice as suggested. Also, if the B/R wire does have voltage when disconnected from the solenoid then look at connector X-09 located above the driver fender well, which joins two plugs, each with a single wire (both being Black/Red). Disconnect this connector and find which one has the voltage on it.

 

eventually you're not going to have people attempting to help if you don't do the simple tests asked of you..

 

I'm getting a voltmeter at work tomorrow so i can check everything! I pulled all the connector on the ignition switch and still having the same problem so i rulled that out....i havent been able to do much it gets dark so early and i work all the time!

 

Does anyone know how i could get a complete wiring diagram for the starter wires?

wow awesome!!! thank you!

 

I think it's the starter cut relay!!!! It just makes sense....i have checked EVERYTHING nothing is melted together at all so thats gotta be it!....anybody know where i can get one? Any thoughts about that being it?

 

Again, if you disconnect connector X-09 and test which end has voltage on it with the starter solenoid wire disconnected it would likely narrow down the source of the problem once and for all!

Also, if you disconnected the 4 wire plug to the Starter Cut relay it would tell you rather quickly if it could be the source of the problem.
