Re: Ammeter Reading
Does the new generator have a voltage regulator built into it? If so, everything below is incorrect. The following only applies to a stock Model A generator which is designed to put out a constant amp current rate.
First check the ammeter. With engine not running, with no lights on, is the needle at the center? If not, note where it is and mentally make that your "zero".
Now turn the headlights on (engine not running). Where does the needle go to? It should show discharge of about -10 amps relative to your zero.
Now turn the lights off and start the engine. With engine running on a fast idle, ammeter should show about 8 amps of charge, relative to your zero.
Note, with this setup, you will slowly discharge your battery at night while driving with headlights on. The assumption is that you will drive for more hours during the day than you will drive at night, which will charge the battery back up.
Hope this helps.
