Hi all,
Does anyone know what pin 8 does on the boiler board?
I got a used MTH 20-3401-1 that has wiring issues (engine speed is inconsistent, does'nt listen to commands, etc.) needless to say i believe I found a short, the drawbar pin off the harness was connected to pin 8, when I believe it should be connected to pin 3 on the 8 pin connector.
Needless to say I can't figure out what pin 8 is actually supposed to be used for.
Thanks,
Dan
