Hi my name is Robert....

Does everything work when you are plugged into power?


Expert:  Robert replied 1 year ago.

Follow ups are included.......

The slide-room normally is wired directly to the battery and if that works it tells me the battery is good, go to the battery and make sure you do not have a tripped breaker, sometimes they will stick one on the cable from the converter to the battery. Most have a tiny tab on them that pops out when they trip, as a general rule they like to stick them 18" from the battery and can be on the frame. IF you see any the voltage to chassis ground should be the same on each post. IF you do not see any or they test good and do NOT have a battery disconnect switch inside then I suspect the converter might be at fault, if you happen to have a disconnect switch inside please let me know that switch is normally near the entry step as you enter, not all RV's have them. I would start by looking for a tripped breaker near the battery.... Hope this helps... Robert
