This new to us 05 HR Scepter, has been here all summer working fine for EMS,DC, AC, post or generator exercise. Last nite it was cold so we ran heat , as we had in the past. This morning no DC loads worked, no heat, hotwater, lights, nothing on Dc, no EMS,ect. NO breakers or fuses have been tripped/blown. We have power to all outlets, ref is running(good!) Microwave, and can run a 120v space heater. To me it seems the 120v is not energizing the 12v distribution system? HELP, could it be the inverter/converter, transfer switch, seliniod, or what ?? All replays may help me. I'm a first time user of this forum. Thanx - Ken "Standing -By"
