Just finished doing the grounding/charging rewire from rotaryresurrection.com, tried to start the car, but it was acting like it was flooded. It finally cranked up and the alternator seized up, literally cooked the belt off. Everything is wired correctly, what the **** happened?

*sigh*...grounding...

You blow the main fuse also?

No, the main fuse is intact.

Obviously, you grounded a wire you shouldn't have. Now you gotta find it.

Any melted wiring anywhere, or just the alt?

Hypothetically speaking, if I accidently grounded the positive wire going to the alternator while installing, would that have caused it to seize up? I don't know if that happened, but it is a possiblity..... just trying to throw out some ideas here.

It would be akin to shorting the battery's terminals together...In other words, a nice big juicy 500 amp flow, with no load. Enough to fry any alt, hypothetically speaking...

See if any of the alt's mounting bolts/nuts have welded themselves to the brackets...

Scary to think what may have happened to the electronics on the car...

The battery was disconnected the whole time I was installing the wires.

did you overtighten the bolts on the alt?

The mounting bolts? I tightened them pretty good. what would that do?

WAYNE88N/A

The alt is its own battery when turning, it doesn't care if the battery is connected or not. This is all conjecture at this point, you need to perform a good visual inspection of all of the wiring you did, and if the alt doesn't turn by hand, replace it as well...

i tightened a few bolts on my alt. turned on the car and the alt was frozen. wouldnt move. loosened them and it fixed it. it clamped it and didnt allow it to move. go check that.

HOLY **** RAZORBACK!! you are a genious!

I just loosened the main mounting bolt and now it turns freely. I still have to get a new belt.

razorback

anytime. i did the same thing.

WAYNE88N/A

Lol, I don't believe it...

Did you guys have the spacer installed?

impulsive-rx7

iTrader: (2)

Maybe there is supposed to be two spacers.

WAYNE88N/A

There's only one on the NAs, don't know about the turbos. It still amazes me that you could tighten the hardware so much that it crimps something inside and locks it up, especially if all of the hardware is there. Learn something new every day, lol...

Well, I'm glad you didn't fry anything, anyway

Yeah, me too! Thanks for the help anyway.

i actually think it kinks the alternator so that it cant turn properly/freely.
