Electrical System Problem

I still have a voltage issue at idle speed!!! Is in not possible to fit a smaller pull on the alternator to over come the low idle voltage problem???

Is your stereo still on when experiencing low voltage at idle speed?

Stereo system on or off it is to low. It looks as if the alternator need around additional 200rpm before it push the correct 13.7 v

Good to know. Is that normal alternator behavior? I would be curious what experience others on the forum are having with output voltage at idle. Does everybody have to crank their engines a little to ensure their batteries are charging?
