[Sentoa] Starting and House Battery Wiring

[Joel Truher]

This is my understanding.  My DC panel has two relevant breakers:

BATTERY 1 == controls a relay that connects the starting battery to the engine.
ENGINE CONTROL == provides power to the electronic engine control box,
and the speed control lever.

The takeaway for me is, to avoid discharging the starting battery,
both these breakers need to be off.
