Default alternator - '89 keep killing it

I have a '89 corvette with a dry cell battery, because of a fairly large stereo system I have installed. I have tried a new GM alt and battery but that didn't last at all, so I went back to the dry cell and a life time Pep boys Alt.
Any suggestions on a better Alt that will take the heat and the load needed?

Not sure if it will fit but the 96 high amp alternator is pretty strong. I think its rated at 140 amps....at least I think I read that here on the forum.

a life time Pep boys Alt.
I had lots of problems with Pep Boy alts. Their lifetime is about 6 months(best) to 1 week (worst) They only replace the bad part in them without checking everthing else. Got my last one from a speed shop (1 year warranty) but it is completly rebuilt. Been going strong for a year and a half :cheers:

I also installed an LT1 alternator with 140 amps. I was turning around my Autozone rebuilds at about 3.5 per year!

This one really rocks! The stock L-98 alternator cant keep up once you add anything electrical, it barely runs for a year on a stock car!

I fried 5 or 6 CD-130's, then I decided to try something else: https://www.corvetteforum.com/techti...=189&TopicID=2

I also installed a ground wire (not in the photos) from alternator to exhaust manifold bolt after couple of friends pointed out that grounding problems are one of the main causes that kill alternators.

BTW. which dry cell battery do you have? There is couple of styles of Optima and I remember seeing many discussions that one of them is not suitable to Vettes.

Regards,

Toni

Yes, it is now taking the place of the rear support rod. I even used the original bolts to attach it. Remember that the ground wire must be equal gauge to your battery cable. I used a thin and wide -type of battery negative cable as it is more easily routed than the inflexible ones. If you wish, i can post a image of it.

Regards,

toni

I guess I must be one of the lucky ones. Have had this vette for five years and am on the alternator I put in when I bought the car. Has anyone looked at an alternator from an RV? Some are reworked GM units that have bigtime outputs. In the 250 amp range. Might be worth looking into if you need mucho power.
