charging system blues

Mike, I think you need a new voltmeter.
Not one guy questioned the condition of the voltmeter.
You must have got tired of reading. :LOL:
If the voltmeter is giving bad information....
The questions then are:
Why is your voltmeter showing just 12 Volts?
Is the Battery down to 12 Volts?
Is the Alternator putting out only 12 Volts?
Or is your voltmeter bad?
