MTH PS3 boiler board pinouts

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

I had an engine like that too and similiar problems. Pin 8 is drawbar, but not sure what used for. In Diesel it is for the slave board. I moved it to the 3 pin with a proper sized wire too. G
