Default Re: dashboard light

how did you test the alternator?

people at the parts stores are sometimes unqualified to test parts correctly and sometimes parts only show trouble once they are warmed by the engine.

with a multimeter did you check the voltage by connecting it from the engine block to the positive battery terminal? it should read 13.5v to 14.5v at at idle and when revving it up.

battery should have 11.8v to 12.5v with the engine and key off
