I have a new Beta 38 with a keyless (CW) panel. I have a 120 amp alternator with an external regulator and a Blue Sea ACR. Two battery banks: a start battery and 4 house batteries. I want to isolate the start battery from the engine (per manual instruction) and depower the panel when I am away from the boat.
I think diverting the brown/white wire in the harness through an on/off switch (40 amp) will depower the panel. Does that also accomplish isolation of the start battery?
The brown and white wire that is connected to terminal # 1 on the multi pin plug is the power in to the panel.
You are quite correct that installing a breaker in this line will allow you to disable the panel.
