I've been lurking here for a few months and solved my electrical problems * I think* from the great threads in this forum, Thanks!
I have a 74 , 31 ft Sovereign
I was getting a direct short to ground. Investigation found 1. a bad connection at the neg to battery fuse holder. 2. 110v short at AC 3. direct short of light fixture wire under light fixture to alum cut out 4. stuck fan at front vent 5. crushed wires in ceiling. ( Yes, I took the ceiling center panels out just to be positive there were not more shorts) 6. possible bad unsoldered splices by PO. behind ceiling panel 7. damaged tv antenia wires
btw, for anyone removing the center ceiling panel, it is hard to get out in one piece and not a fun project on a hot day. I ended up cutting mine in 3 pieces and will replace with new panels.
Univolt is the type with trailer bat and tow vehicle bat input on the left and 4 12v
fused circuts on the right. It is located at bottom of bath closet between tub and trailer side wall. My knees hurt and my back aches
These problems , electrical, not my back, are all resolved, after 3 days with a digital multi meter.
1. 110v shore power works fine, 110v are going to the univolt. With the bat. not connected, 12v
do not come from the univolt ( only tested with a weak bat. ) Is all the juice going to trying to charge the bat at this point? or is univolt shot? ( planning on replacing it anyhow) With a bat. charger hooked up, 12v
2. where can i get a wiring diagram?
3. where can I get a tech manual? I have the small 30 page owners manual only.
4. Where is the switch for the front vent fan?
5. The 110v circuit breakers, 2, feed the ac, the oulets and the hwh. I have not investigated this yet as it is even harder to get at, as it is located above the hwh cabinet in the rear. I did notice that the breakers are jumped together on the power out end. Is this normal? Seems self defeating.
6. I will be replacing the ceiling lights with leds that only have a 10% voltage variation allowance. I have read that the univolt puts out 18-19 volts. a. do the new converters put out that much? b. Is the solution simply to install a voltage regulator in line on the light circuits? If so, are these readily available ( sorry, I haven't done my research on these yet)
