Alright guys, yesterday my buddy and I were installing the new alternator bracket and some higher quality bolts yesterday, and we were convinced we wouldn't need to remove the negative cable on the battery:rolleyes: (I Know, lesson learned).
I was lifting the alternator, and he was holding up the main cable that goes to the alternator, it slipped through his hands, and i'm pretty sure it's the alternator it hit, and sparked.
Long story short, car died while I was driving= I'm assuming the alternator is fried and I need to replace it.
Just to make sure before I purchase a new one.... there isn't any fuse/resistor/relay that could have blown is there?
Let me know asap, so I can figure out what I need to buy.
I'm 99% sure it's new alt. time.

alright guys, where is the fuse link?
Alt tested, and alt good!
I cleaned batt. terminals, im cleaning the harnesses with electronics cleaner.....what can it be?
Alt good, but not charging batt? The batt is 80% dead (guesstimate), I can jump the car, but it just shuts down after a minute or so.

On a 97 I believe it is on one of the studs that attaches to the power distribution box. Try following the big wire that comes off of the alternator.

I've fried my megafuse before...:rolleyes:

Have your alternator checked first. If it's not that then you either got the regulator (on the alt) or the megafuse (like mentioned before, it's on the engine side of the Power Dist. Box.

Alt. tested and the alt was good.
Does this mean the voltage regulator could STILL be bad?
I cleaned wire harnesses with electronics cleaner, and sanded down the wire connectors to make for a clean connection.
BUT, now when I start the car, it will fire, to the point where the rpm's on the tach shoot up, and as they come down, the engine shuts off. EVEN with jumper cables attached to a running car. What would that mean? Car shuts down as soon as it is fired. That tells me, even with the power from another battery....my car is NOT getting juice to it's components, regardless of how well/or how poor my car's electrical system is.

Mine as well. The only way you can test the fuse if you don't have an ohm meter is replace it. If you shorted that wire than the fuse did it's job and protected everything else

Remember that there are 2 fuses in the charging system. The 175amp mega fuse from the alternator and the 15amp fuse (#11 in the high current fuse box) for the alternator field/regulator.

I just replaced the mega fuse, so I'm going to go take it out for a test drive. If I get stuck...who's coming to get me????:D

I had an alternator issue with my old 96 bird, the fuse where the two bolts are on the side of the power distribution box went out.
