Hello,

Unless you need more than 100 amps, the stock type alternators and external voltage regulators are what we recommend.

We have a Bosch authorized rebuilder upgrade Bosch alternators to 100 amps for customers who have added stereos with amplifiers who need more than the 55 amp Bosch remanufactured alternators that we normally install.

We had the rebuilder custom build a 200+ amp alternator for a customer with multiple high output amplifiers in his car. We did however have to add a dual drive belt setup.

All the above mentioned alternators bolt directly to the block on late B18 and all B20 and B30 engines.

And the early B18 blocks can use these alternators with an easily available conversion bracket that sells for $35.00.

The alternative is to convert to a common Delco Remy(GM) alternator. You can fabricate your own mounting bracket or buy one from Ron Kwas and I believe he can supply you with installation and wiring instructions that include how to make the "AMP" light work correctly.

Yes, this alt (not generator) actually stops turning after some start ups, belt starts to squeal & smoke. then i turn car off & restart without any problem (very strange). I assume there is a bearing problem, or something loose inside the alt. either way i want to replace it. The simple & common GM alt sounds like a good way to go for me. I wasnt aware there were generators on 72 volvos. THX!
