I just bought a lovely 1986 Champion TranStar. It is in fantastic shape. The only thing I can't get to work right now is the electrical. According to the seller, (someone I know), they never had a problem with it. I checked the cord, bought a new adapter, checked the switches on the power converter. They are all on. I plugged it in at home and at an RV park w/ elec. I don't know what else to check. Unfortuantely, I don't have an owner's manual to refer to. Any ideas? I am a first time Rv'er so there is a lot I am learning.
