Is it possible for a Mando alternator on a 1990 260 MerCruiser to just work here and there? I took it off and had it checked out at a reputable shop. It tested out just fine.
My volt gauge reads about 12 volts 90% of of the time. At times it jumps up to about 13.7 volts. The gauge is working correctly as my fish finder backs up the voltage reading. Would having 2 batteries on board make any difference. They run off a 3 way switch. 1 all 2 off
