I am trying to help a friend with an RV 6A solve his alternator problem and could use some advice on where to start. This is a ND alternator with Ford regulator. Everything was fine until the volt meter started showing 15.5 to 16 volts. Then an over voltage alarm came on on one of the instruments. He thought the regulator went bad so he replaced it. He still has 15.5 to 16 volts now. If he didn't have a good ground from the regulator case to the airplane would that have any bearing? He also plugged in a voltmeter in the cigar lighter and it shows the same voltage as the instrument in the panel so I'm sure it isn't the gage. Where should I start looking? Thanks in advance.
