Have a 2015 Bighorn 3875FB bought in 2014. About a momth ago started having trouble with opposing slides in living area starting and stopping. Replaced batteries and 50 amp breaker. Still having same problem. One day on taking slides out voltage monitor went completely blank for a few seconds then came back on. Level up system also stopped and monitor went blank then came back on. We are stumped. Is there another breaker we need to replace or could it be the hydrolic pump motor? Any suggestions are appreciated.
