Thanks for all the responses. LMC sells the converter (for motors). Smoke came from that converter. Yes, there is a single cloth covered wire from heater motor (6 volt original). I gave it 12 volt power and it blew like a mini tornado. Someone here said the motor would burn up on 12 volt power. I would be inclined to buy the 30 amp rated converter if it solved the smoking problem.
Also, I have the original 3-way toggle switch with 2 connection points. I'm not sure how that would hook up to the converter and then to the signal cloth wire on the heater motor.
