Both the engine and domestic systems on my mobo are 24 volt with both battery banks charged by a single altenator. According to the voltmeter, the charging voltage varies frequently between 26 and 28 volts but every so often it flicks over to 30 volts momentarily before returning to 26 or 28 volts. Do I have a problem with either the altenator or the voltmeter or am I worrying about nothing. Having recently had some £800-worth of new batteries fitted I am anxious not to cook 'em!!
ps as this boat is new to me, I don't know whether the charging voltage has always behaved in this way. Many thanks for any advice
