It should be much zippier than that.

To preserve the life of the reverse board, the smoke unit should not be connected to it in any way, even through the switch. The elements go bad - to a short - too often and take out the power transistors.

I disconnected the smoke unit positive from the switch to see if that made any difference with the motor and the heat in the transistors.  It didn't.  With the motor running for about 30 seconds at 50% throttle the transistors got hot enough to only leave my finger on them for a sec or 2. 

Is it safe to assume the motor is bad and pulling way too many amps, thus heating up the transistors?

As far as rerouting the smoke unit power, can I tie that into the wire nut that has the 2 wires from the pickup rollers as well as the gray wire from the board?  I don't see any way to power the smoke unit without it being tied into some wire that connects to the board.
