Reply to "DREU reverse unit wiring connections for AC motor"

I bought this board and the mentioned cables to run a PW FM Train Master. Had some problems getting it hooked up, my fault. It works as it should but the MOSFET’s get VERY hot. After about 5 minutes of running, not pulling any cars, the MOSFET’s get so hot, you can’t keep your finger(s) on them. The motors on the FM are extremely free spinning and require very little voltage to get it moving with a mechanical e-unit. The board is shown to be for a two (universal) F unit look. Any ideas what would cause this or is this the nature of how this works? FWIW, I ran the FM for about 10 minutes and pulling 4 postwar cars. The board did not fail, but got very hot. The aluminum heat sink, was even untouchable.

Thanks

Steve
