On a 6 volt negative ground alternator that test 6.57 Volts with headlights on
low beam and the Amp meter reads 5 amps +. With the headlights on high beam the voltage is still testing 6.57 volts, but the amp meter is now reading
-1 amp.
Is there a problem with my amp gauge? I don't understand a constant 6.57
volt reading and the amp gauge dropping off as mentioned above.
I can increase the RPM's and the amp needle does not move. (still showing
6.57 volts) I can turn the lights off and amp needle does not move.
I can shut the engine down and restart, the amps needle goes to 30 + amps,
and then slowly decrease to 9 amps and stay there until I turn the lights on, then it is back to as mentioned above.
Any answer or help will be greatly appreciated.
