I recently installed solar on my roof, an inverter and a gopower automatic transfer switch. When hooking up the transfer switch I had to disconnect the RV battery charger from the breaker panel to connect to the switch. That breaker had another wire spliced into it. I disconnected that wire and connected it back into the breaker and connected the charger to the transfer switch. My problem is when I completed hookups and turned everything on. I could not get dc power to my slideout. I shut the breaker off that the extra wire from the charger went into and it works fine. Anybody have any idea what that extra wire goes to and why it controls dc power when off to my slideout. The breaker is the CONV/GEN breaker in the picture
