On my somewhat new to me boat
there is a BEP battery monitor
(volts, amp draw and water/holding) which monitors both the house and the starting batter banks. I noticed after an overnight both banks were reading the same voltage which got me suspicious. This was confirmed crudely by turning on various loads and watchings the voltage sag on both banks be the same. I took things one step further and physically disconnected the starter battery
and it still showed voltage on the starter circuit.
Any thoughts on what typically is wrong in these situations? Looking for ideas before I start tracing out every wire.
Few things of note:
has a 3 switch battery distribution center (house/parallel/starter) which I keep in the ON/OFF/ON position
- Have solar
installed, simple install panel > controller > fuse > house bank (on positive) and the negative bus bar
- Have a VSR. Engages: 13.2 VDC, Disengages: 12.7 VDC. I'm not exactly sure which side of the circuit senses voltage or where the alternator
is wired too. I thought perhaps the solar
voltage was keeping the relay closed allowing the starter to be drained but I think that's somewhat of a stretch.
- Since buying
the boat, I installed solar and a new battery charger
. I can't say for sure if it worked before I installed these. Perhaps I really did something dumb and paralleled things but the installs were pretty basic.
Any ideas appreciated!
