scarab 165 always hot circuits?

[jb32566]

I am in the process of adding a second battery and tracing wiring.
afaik, there are 2 always hot, fused circuits. the first is the bilge pump. not sure what the second is. i'll go through a systematic process to track it down tomorrow. just wondering if anyone else already knows. I'm thinking _maybe_ a house keeping circuit for the stereo ?
thanks!

bumping this thread because i don't understand if the pump in the 165 a.) is automatic, but only runs when switched on or b.) is completely manual or c.) something else.

Should I always have the bilge switch in the up position or is that "manual" and even in the normal position there is a float override?

Sorry naive question, but i'm finishing up a dual battery and charger install and adding a backup bilge on a float switch is another project/mod I am strongly considering.

I guess I could just pour a big ass bucket of water in the bilge and see what happens. If it's in the schematics or manual, I won't be offended by a RTFM response

Thanks.
