I had my 1990 rrc idling in the driveway last week and had the pleasure of watching all the lights slowly dim and the engine slowly die. Obviously the alternator.
Today I replaced the old/original alternator with a rebuilt one. Got everything hooked up and jumped to start, yet she died about 5 minutes later in the same way. I tested the amps at the alternator and it seems to swing between 0-75 (alternator is a 100). The tachometer also does not work consistently when revved in neutral.
Have I definitely been sent yet another bad alternator?? Or could there possibly be another issue?
