battery disconnect switch

[penny123]

Help! I have a 1998 National Dolphin motor home class a.  Lost power to bedroom 110 & 12 v  but still have 110 in coach no 12 v anywhere. I am plugged in to 110.  I have replaced  Intellitec BDO battery disconnect switch . The latching relay is working and I have checked all wires and relays all seem to have power. Breakers are good fuses are good.  converter is good and working, batteries are charged and good. Still nothing has changed. any ideas? 
Thanks Penny

Welcome!!

For the 120Volt, it is likely you have popped the GFCI outlet since only several of the outlets are not working. A single GFCI outlet can power up to 6 or so other ordinary sockets. Look for an outlet with test buttons on it. It is likely on a circuit that includes the bathroom sink, the kitchen sink, the patio plug and perhaps a couple more.

The 12V system is based on fuses for distribution. If the converter is really working (there may be a fuse or two on it that may need replacing), you should have 12V at all the fuses. How have you determine that they are all ok? (Looking is very often not sufficient, you need a meter.) Measure the voltage at the battery terminals while plugged in, you should read about 13.4V or so if the converter is functioning correctly.

Again, for breakers working, looking is seldom good enough, breakers often do not show by flipping the arm enough to see. A meter can help but flipping them off then on again is the best way.
