1 Voltmeter Readings on Sun Sep 26, 2010 2:29 pm
However, as the revs and speed rise further, the voltmeter drops down to 11V and even 9V by 80 MPH.
At no stage does the red alternator charging light come on on the instrument panel.
The battery is new.
When the speed and revs reduce below 4,000 RPM, the voltmater returns to show 13V.
Is this normal or perhaps symptom of an alternator problem ?
