I am working on the sheriff's m1113 and have run into a problem. The batteries drain over night. I have disconnected the negative from both batteries to stop it but what is wrong? with the front battery hooked up as it should be and the neg off on the second battery, I can flip the start switch to run and the brake light comes on and the wipers will run. no hornbut I think the heater fan also runs. Is this normal and I need to look elsewhere or is something hooked up wrong. I was going to put in a battery disconnect switch but with this situation would I need two?
