Since Richbark has not posted his results yet, I will post mine. I installed a 143amp alternator in my 1993 190E 2.3. I got the alternator from Pat at Potomac German Auto.

The 190E originally had a 70amp alternator. I swapped pulleys and rotated the rear housing so the wiring would line up. It fits and works perfectly! I have not upgraded the cable to my battery yet, but it seems to be working fine for now.

I don't have any pictures yet or any power measurements but I will try to get those this week.

Thanks again for the research Dave!

Regards,

Don
