I have noted this season while running the blower or the ballasts or the radio my voltage drops heavily and the boat will only be 11v or so, and my gauges start going crazy. I run tenders and chargers regularly. I have an 05 escalade C4 storm series 3 with Black scorpion motor. Has anyone found a good high output marine grade alternator?
Looking at getting an on shore charger, but am unsure on which one to get in regards to the number of amps I need.
I have 2 dual purpose group 27's. 6, 12, or 20 amps. I know that bigger is not always better.
