I thought I disconnected all the 24v wiring when you had your bus over here. Everything should be 12v, you just have a lot of left-over relays that aren't doing anything. You need to get 4 batteries in the left side battery compartment (I recommend 4 6v golf carts hooked for 12v to run your house system). Corroded wiring in the driver's area is a matter of rewiring. Everything should be 12v.
Yes Geoff you did, and now I want to remove all the 24 volt wiring and relays that aren't being used. I want to have the genset charge the batteries when it's running. I am thinking on just rewiring a new house battery system, but not removing the old wiring untill I see if my wiring works
