I keep revisiting this topic and have gone back and forth a few times. There's definitely advantages to different wiring
schemes. Bottom line - with the boat mostly charged on shore power
, I don't need the electronic battery
combiner (at this time). The charger
has an echo charge, so both banks should be properly charged.
With the house bank drawn down, it is a bad idea to put house and start banks in parallel. Because of that, I've removed the Cole Herse solenoid combiner from the circuit. If I want them in parallel, I can always put the Battery
Selector switch on Both.
The remaining questions are -
is wired straight to the house bank, with a Xantrex digital alternator regulator
. This makes sense, as the Xantrex module monitors voltage, temperatures, etc. I am going to keep this. However, the only way to charge the start bank is to put the battery selector switch on "Both" -or- to add back the electronic battery combiner.
Finally, the starter is wired direct to the start battery - I'm thinking about moving this to the common of the Battery Selector switch (1-2-Both-Off). Then I can select which bank is used to start. Does anyone see any issues with moving the starter to the battery selector switch?
I know it has taken a while to get to this point. I think I'm understanding the wiring, pros and cons, and making decisions on the best configuration for our intended use. This drasticly cleans-up the engine
compartment, removing 4+ heavy wires and rerouting others! I appreciate everyone's input.
