Scratching my head. Presumably the point of the second battery switch is to switch some circuit(s) open or closed. But to me it's weird. I'd generally expect the switching to be on the hot side of the circuits, and all grounding to be (unswitched) to the engine block and therefore the prop shaft. (Not that I'm all that experienced with boat electrical systems). Where does the black cable off the "common" stud of that second battery switch run to?
Regarding the #1 battery, an easy test to isolate battery fault versus other faults would be to connect it to a known good charger (only). If it won't charge up or hold a charge, it's the battery.

Thanks for all the feedback regarding the bilge re-wire on my 30-1, very helpful advice really appreciate it. I’m now going down the rabbit-hole of electrical and figured I’d post a few photos because maybe something is glaringly obvious with my current setup and one of you can point it out. I discovered a secondary battery switch today for all the negative battery terminals from my #2 house battery under the galley cupboard, not sure how common it is to have two main battery switches like this. Also found out, as I accidentally left the main battery switch on #1 battery the other night from too much vino, it’s still dead and hasn’t recharged even though I’m connected to shore power (albeit a sketchy shore power hookup) to my True-charge battery charger. Could be one of two things: battery #1 is toast might remove and do a load test, or try to find if there’s a power draw somewhere down the line that surpasses the 10amp charger. Surveyor thinks it’s a badly hardwired autopilot and noted curious oxide on the prop, but I don’t know enough about bad wiring. So anyway here are some photos of my current setup: https://drive.google.com/drive/folders/0B_lwczpvPcEHd3R5NXVlNC1tRkE?usp=sharing Photo #1: Cabin main switches - lights illuminated from lazarette being open. Photo #2: New battery switch discovered under galley counter port-side for negative terminals. Photo #3: Truecharge 10amp Battery Charger hooked up to shore power. Neg and Pos go to battery #2 and a third Pos wire goes to battery #1. Photo #4: Truecharge wiring on batteries. Photo #5: Wide shot of negative terminals(below) going in port-side cupboard under galley counter to main battery switch #2, Pos terminals going to main Cabin for battery switch #1. The way I see it I have three options: A: Call a marine electrician - I did this morning and he’s booked till September figured I may as well just keep up the detective work B: Something is glaringly obvious about this setup and one of you points it out C: Keep digging Chris Hobson S/V Going C&C 30-1 #615 _______________________________________________ This list is supported by the generous donations of our members.
