Just brought back our Cougar 30RLI from storage while the backyard was landscaped and discovered no 12V lights, etc. worked. Checked the batteries with a voltmeter and the reading was 12.8 - plenty of charge. Voltmeter confirmed electricity pass the batteries. Checked the circuit breaker fuses - all okay. Checked the converter fuses - all okay. Plugged in the 50amp and the lights, etc. all worked. Getting frustrated now !!! Disconnected the 50amp. Connected the trailer to the F250's electrical plug on the hitch - lights, etc. worked. LIGHT CAME ON, what about the battery disconnect in the pass through storage. YEP, it was off - turned it on and "let there be 12V lights".
Sat down and had a beer - lesson learned the hard way but a lesson was learned.
You can stop smiling now
