I have two 240s, an '88 with auto and A/C and an '89 manual with no A/C. I've checked a few on-line suppliers and they all list several amp ratings (IIRC from 55 amps up to 80 amps), so for future reference, which one would I need for each car? Thanks.

PS: Neither my Bentley nor Haynes manuals show what amperage alternator for which car.

Re: Which alternator? (John2x240)

Unless you run ten headlights and twenty speakers 55 amps will work just fine and 80 is better for either car.

Look at the existing alternators (and regulators) on each car then check this out...

...to determine which system(a) you are currently running on each car.

Most busy alternator/starter shops have reman units that will bolt right up with no changes to the pulleys or belts.

Re: Which alternator? (gdill2)

Both alternators look like Bosch re-builds. I tried to get the numbers off the stickers but they wiped off when I tried to wipe the crud away. I guess I'm gonna have to get my hands dirty and pull the alternators to see if there's any other identifying marks on 'em. I was hoping that someone would know what the spec alternators were without having to do this. Oh well.

Re: Which alternator? (gdill2)

Thanks George, I'll check out the links tomorrow. Right now it's way past this Old Fart's EDT bed time.

Re: Which alternator? (John2x240)

That's interesting info George, thanks. I don't need one immediately, but I have found one at a local on-line supplier; a Bosch re-man 80 amp p/n F4000-10022.

Re: Which alternator? (John2x240)

Any alternator for a redblock engine will fit and work just fine. The small later Denso and Bosch alternators from late 940s require a larger ring terminal on the wiring harness and might require a different tensioner setup, but other than those everything is just a straight swap unless you get an alternator for a pre 82 car (external voltage regulator).
Turbos used 55amp alternators, other than that as far as I know 70 or 80amp alternators were the norm on 240s. You should be just fine with a 70 or 80 amp. I'm using an 80amp in my 242ti with lots of electronic toys. The 80amp is still adequate even with the heater, radio, headlights, rear defrost, and side mirror defrost going.
