You are Correct!
It is a 90 300e.
I am getting 18.77 volts running. I would like to replace the regulator first and see what I get, but we'll see.
If I have to go the entire alternator route, does anyone know off hand if it is a 70 or 80 Amp Alternator?
Oh by the way G-Benz...If you have experience in changing that alternator out...please please...feel free!!!
