A couple of years ago, I installed ERR Cruise Control (Cruise Commander M) in a Lionel NEW HAVEN Mountain 6-28058. ( I also installed GRJ's Chuff Generator and Super Chuffer II.)
The engine ran great. But after a period of non use, when I tried to run it, it made a hum and a short circuit.
I have removed the boiler shell and looked for a pinched wire. I could not find one. When I disconnect the red wire from the 4 wire plug on the ERR board that connects to AC Hot, the short disappears. So it appears to me that the short is coming from the ERR board.
Does this seem correct?
If the short is coming from the ERR board is there a way to confirm this or repair it?
Or do I need a new ERR Cruise Commander M board?
