OK, I got it to work. I'll let you know in case it would be of some help to someone else in the future. I thought ( and was told ) the re-igniter might be bad. Bought a new on and found that the ground wire to the old one was broken. repaired that but still nothing. I could block the start switch open and light it manually, but suspected that when it got to temperature it wouldn't relight. I wasn't getting 12 volts to the re-igniter, though all of the connections were good. I traced a wire that went into the wall next to the refrigerator and remembered there was a rocker switch there that no one could tell me what it was for. You guessed it, it turns the 12 volt on and off to the re-igniter. Flipped the switch and it started to work. We bought this camper used from a dealer and couldn't contact the previous owner to ask questions. Now, I need to find out what the key switch on the outside of the back door does.........
