When I bought my boat (Santana 28) it had one battery, There was room for two batteries in the battery box and
as I had purchased an ST2000 auto pilot I decided to add an extra 'house' battery. The house battery is charged by
a small solar panel (about 7 or 8 watt) and after advice from the dealer I put a regulator in line because it sits in the sun
all day every day. Poking around the boat yesterday I put a voltmeter across the the batteries to check the charge
and the house battery read 15.3 v. The green light on the regulator was on but dim, at that voltage I would have
thought it would not be on at all. Is 15.3v over charged ??. Do I have a problem ?. or is that reading acceptable ?.
If I disconnect the battery from the solar panel the green light flashes. Is all OK ??.
