What is acceptable voltage @2000 RPM with lights on?
I replaced my alternator a few weeks ago with the same 35 amp alternator and after cleaning the wire contacts I noticed it would now hold 14v at idle with lights on. Last night I went to a cruise night and ran the usual 14 - 14.5v, but on the way home with lights on, I noticed it was running about 12.2 -12.5v @ 2000 RPM, less at idle, but lights did not dim. Normal? Acceptable? Why the change? Color me confused.
