Thanks for your suggestions. I have been working on the isolating the draw and have had no luck. My problem circut is circut #3. Circut #3 seems loaded. It has the heater, Galley light above the sink, Galley lights in roof vent, outside light above the door, and light/vent with fan aft of the galley which is the first vent in the bedroom. However even when I disconnect all these items the test light at the fuse in the univolt circut #3 remains on. Further I have isolated all other uses on the other 3 circuts and found that circut #2 only is used for the aft road side (3 Bulb) light and nothing else. All that said even if I distribute the circut loads more evenly, I can not find the draw on circut #3.
It is beganing to occur to me that I must run a new wire from the univolt fuse to the lights and furnace. Not a easy prospect.
Any other suggestions? Is there some other possible draw on existing circut #3 that I am missing?
Circut #1 operates the bath light, aft top vent/light, rear closet 12volt charger
Circut #2 Only found the aft road side bed light
Circut #3 Furnace/fan, galley refer top vent/lights, outside door light, and Galley sink light.
Circut #4 Dinette reading lights, outside light, 12volt charger above the refer.
The water pump, panel light, water tank sensor, and waste tank sensor run off the front electrical panel.
Am I missing another potential draw in the electrical system? ..... some other appliance or light? ( I am assuming that the running lights are on a seperate circut from the TV)
Thanks again, John
PS the Owners Mannual does not have a 12 volt
electrical wiring diagram, just for the univolt and 110.
