Battery Cut Off Switch Wiring and Slow Drain

[pat2886]

I noticed at the end of last year something was wrong with my battery kill switch wiring. When the fifth wheel is parked and battery kill switch off I still get power inside the trailer. Almost everything will work minus the slides. I bought this trailer second hand from a dealer and have no idea whether or not this is normal. My only concern is that this will continue to drain my battery. I am going to post some pics of my current wiring. Any suggestions or feedback is appreciated. Thanks.

Looking at your photo, you have 2 leads on the "Battery" side of the switch and 1 on the "Load" side that feeds that distribution bus. So the battery is still connected to something even when the switch is off.




Look at the left terminal on the back of the battery switch. Is the lead that comes in from the top the wire to the battery? What does that wire and the one that goes down to the self-resetting breaker go to? One of those must be your parasitic load causing the battery to drain (unless the battery is old and just self-discharging).

I have one that ran directly off my battery feed like that from the factory and it went to a slide out.
