F32 1990 DC Rewiring - Electrical Diagram?
Posted: Thu Mar 28, 2013 9:59 am
I posted my rant in my rant thread, now I have a question for F32 owners.
I want a house battery. Last night, in my deep dive, I didn't have any schematics or wiring hook-ups to look up. It looks like my boat has 2 batteries for the engine, they are wired into a DC circuit breaker just above the bilge, between the engines. The breaker panel has leads that go to the starters, 40 amp charger, and to the panel box in the salon. Aft of the DC circuit enclosure, there is a third battery for the generator set, it's wired to a Perco switch on the wall. The Perco switch is a 2 selector switch and is wired to the 8KW genset and back to the battery bank circuit box I just mentioned. The existing charger has a needle that should indicate current, but it's pegged at 40 amps, even when all power is off in the boat. It's also directly above the port shaft log and is completely rusted out. I can't believe it works.
So, I want to add technically a 4th but really a third battery for the house. I want to replace the charger, as I mentioned before, with a 3 bank charger. I don't know if I think that Perco switch is needed and wonder if that's an add on by the PO I ranted about in my other thread. I want a deep cycle 4th battery for DC house loads(I'm a live-aboard), and obviously flooded cell since that's what all the other batteries are on the boat.
I'd like some advice on how to rewire and where to put the switch. I'm not a DC guy, very little experiene. My intution says that each engine ought to have it's own battery. It seems like I want a switch for just 2 battery banks, with one going to the existing 2 battery banks and one to the house bank. Are there any wiring diagrams available on line and has anyone else rewired/altered their system? What makes the most sense? I appreciate any advice.
