Default Alternator issue

Hey guys

I had an issue where my alternator rubbed against the axel

It was fixed. But a year later I had trouble. The cable going to alternator had got hot and broke off. I repaired it by splicing more wire too it

It happened again. The insulating plastic metaled I broke the bad part off. I was good for a few months. I think I should have used a plastic washer or something to insulate it better

Again it happened but the threaded stud it bent and the nut is stuck. The stud just spins. Any solution? I have a spare alternator but I donít want to have to take the axel out

I understand that this does not necessarily help or answer your question, but why did your alternator hit your axle? Why do the wires keep breaking? Did you correct the underlying problem? Cause this seems more like a symptom than the disease. If I had to guess I would say motor mounts are letting the engine move too much.

As for the stud, I am not sure how well I understand the question. If you just want to tighten the stud on, you can usually tighten it on by putting two nuts and tightening against one another. Like you do to pull wheel studs on. I'm sure that somebody can explain it better or I'm sure there is a youtube video of the technique. If it is too bent to use, if you have the room, you probably can cut it off with a dremel and put a new stud. If there are actual electrical connections to it, there is plenty more to consider.

It would help if you could post an image of what you are working on.

IMO there is not a good fix if the stud is spinning in the housing, without removing the alternator to repair or replace.

Changing out the alternator will likely be your best choice for a "non-hillbilly" fix. You don't have the remove the axle to replace the alternator. You can just take the torque struts loose and tilt the engine. I did a thread on it several years ago. Here's a link:

The "Handy" Alternator Change Out - Motor Mount Technique


For the hillbilly fix, do the following:

1. Take small needle nose Vise Grips and straighten the alternator stud.
2. Hold stud above or below nut with the small needle nose Vise Grips.
3. Remove nut with wrench while holding stud with Vise Grips.
4. Put on new lead wire.
5. Tighten nut with wrench while holding stud with small needle nose Vise Grips.
6. Pray that alternator works with spun stud.
7. Start engine and see if alternator charges.
8. If Alternator charges, pray again thanking the Lord for answering your prayer.

I have found that heavenly intercession is often required when fixing things the hillbilly way.

I agree with Mike on this one. Once that stud starts spinning, you HAVE to remove the alternator and crack the case in order to do a repair. Since you have another alternator, I'd just follow Handys directions and change it and then when you get the time, open up the old one and see if it's fixable. But I'm a lazy, cheap bastard and do things my way.

Hey guys just an update. I had the car on jack stands. Before I started pulling the alternator I was able to tighten the the stud nut. But the threads were messed up. I checked and it was putting out juice, 14volts at battery 12.5 with engine offs. I ran a brand new wire from battery to alternator. I stripped the wire wrapped it really tight around the stud. Used zip ties to hold it to stud
Then used dialectic grease and heat shrink.


I know itís a bull shi t repair but it will keep me going for now
