Speaking of electricity, perhaps someone might have a good wiring suggestion which addresses a "problem" I "created" when I did a rewire a few years ago.
My system uses a small Optima AGM
and 2 - AGM
8Ds for the house bank. The Optima is charge by an Echo charge.. whether when running the engine
or on shore power
charge (rare). What I found is that the original wiring "harness" for the engine wiring also includes the engine instruments and engine lighting as well as a bilge
blower when the engine is running or even the key switch left in "position 1".
Effectively the Start battery not only starts the engine, but once running operates the blower and the instruments. This results in a constant drain on the Start battery and the Echo charge seems not to be able to keep up. I suspect it is mostly the blower sucking up all the amps.
I suppose one solution would be to remove the echo charger
and install a device which distributes and (isolates) the alternator
output to both batteries so I could get more amps into the Start than the Echo charge pute out. Would such a device sense the drain on the Optima and keep it topped up? It makes no sense to move all the loads noted above to the house bank.
What say you?
