Can anyone who has a properly running e30 m60, with a normal 500rpm idle speed (after it warms up and settles), please check your voltage at idle?
I need the following:
1. Voltage at idle, with engine warmed up and RPM settled, with NO lights, A/C, blower motor, etc. *After* the engine is warmed up and settles to the lowest idle speed
2. Voltage at idle with headlights and blower motor on high (This is what I'm really looking for)
I ask because I'm on my third Reman alternator and second battery, and still seeing only 12.3v at idle with lights and blower on. Without them on, it's 14v. If I give it any throttle to raise the RPM, it'll hold 14v with everything on as well. It's almost like the alternator output is not enough at 500rpm, but that is the spec for m60's. My battery voltage with engine off is 12.6v.
