Alternator Bosch or GENERAL MOTORS

Fcp euro has an 100amp bosch one that works well. They have a lifetime warranty too.

Funny enough, I just did this dance today! Found a nearly new looking Bosch unit that someone had already kindly removed from the wrecker's car for me. Got it installed and tested exactly like yours though, so I'm happy.

imo take it back and grab a new Bosch from FCPEuro - https://www.fcpeuro.com/products/volvo-alternator-bosch-al157x

There is a Bosch unit that will fit with the same connectors, but the pulley is usually different. I went to a local auto electric shop and they asked about the current I wanted at what revs and they built a Bosch unit with the appropriate coils and fitted my old pulley. Plug and play, and it's been flawless for 10 years or more.

90 amp Bosch alternator I'm using for my 8V motor. I upgraded the +12V wires to 4AWG from the alternator to the starter and the starter to the battery. Make sure your grounds are good. Battery to frame and to motor. And alternator to motor.

Have a look at Rockauto.com

They have Bosch remans in different sizes.

If you go for a bigger output alt, add a fat cable between the output and the battery via the starter terminal, as the two wires that carry current to the battery via the starter terminal will then be undersized. The cable cost is minimal.

I've replaced the alternator Bosch 0124615028 with an identical part number one. Then I replaced the F00M-145-435(or 385 depending on where you look) regulator on it with a AS-PL ARE0075P. Both regulates to the same voltage, 14.2V.

Even brand name remans like Bosch and denso are suspect but generally much less so.

I recently had two brand new Bosch remanufactured alternators fail. One after six weeks, and one was bad right out of the box.

I was driving the Mini when the engine began to struggle at idle and then shut off, refusing to restart. The starter engaged but hit a wall of resistance. After getting it home, I found the alternator was completely stuck. The one I replaced was a Bosch. Its bearing had failed catastrophically, and the pulley would not move.
