Electrical question regarding batteries. I run three stereo batteries and one starting bat. The last time I had the boat out I started getting an over volt on one of the banks according to the touchscreen. Not sure which bank it was but one bank was showing 13 V and the other one would Get as high as 15 or 16. My first thought was the alternator, but doesn't make sense if it's only happening on one bank. Are there two different voltage regulators?

Just one regulator. If you boat has the Batt Com VSR or the Promariner unit, I would suspect it is failing.Mikes Liquid Audio: Knowledge Experience Customer Service you can trust-KICKER WetSounds ACME props FlyHigh Custom Ballast Clarion LiquidLumens LEDs Roswell Wave Deflector And More -
OK, so you think it could have something to do with the onboard charger even though this is happening when I am using the boat and it is not plugged in to the ChargerComment

Not replated to the out of use charger. The Batt Com or ProCharge Voltage sensing relay is a separate unit.Mikes Liquid Audio: Knowledge Experience Customer Service you can trust-KICKER WetSounds ACME props FlyHigh Custom Ballast Clarion LiquidLumens LEDs Roswell Wave Deflector And MoreComment

Thanks for the information mike. I will look for that part next time I am down to winterize the boat. Would it be near the battery switch? Also, any way to test or should I just replace?Comment

Whichever device you have, it will be close to the batteries. Likely on the transom.
The batt-Com is a black box with 3 4ga'ish sized cable attached. 2 are to the battery B+ posts and 1 is a ground to either a battery B- or a ground BUS
The ProCharge is white and also has 3 4ga'ish sized cables. 1 from alternator and one each to each battery B+, as well as a small ground cable.
These units can be tested with a single volt/ohm meter.
Batt-Com testing; With the engine running, you should have alternator (13.5-14.5) voltage on both cables that go to the batteries. If there is only alt voltage 1 cable, then the unit is not closed and not charging the house battery. Just remember to use the large ground for your meter's ground probe.
ProCharge; This unit is a little harder to test. It has some status lights, so use them, but verify with meter. There should be alt voltage on the one large cable from the alt. There should be alt voltage passing through the unit to either the main, house or both.Mikes Liquid Audio: Knowledge Experience Customer Service you can trust-KICKER WetSounds ACME props FlyHigh Custom Ballast Clarion LiquidLumens LEDs Roswell Wave Deflector And MoreComment

Thanks again. I will do some testing when I get to the boat.Comment
