Re: Ford chassis battery keeps going dead.

My Ford chassis did the same thing. There are things that you can't shut off with out disconnecting the battery from EVERYTHING.
Go to a boat sales and service business. Buy the battery disconnect rotary switch and install it at the positive lug on the battery. Then you will be able to disconnect your battery. Also switch out your batteries to AGM batteries. They do not lose charge while sitting like lead acid batteries do.
