Bobacuda Posted January 9 Report Posted January 9 (edited) Small aftermarket heaters are available (and reasonable) through Amazon. However, they are all 12V negative ground. 6 to 12V step up converters are available, as well. Is anyone using a step up converter? And if so, how has the positive ground affected it?

TodFitch Posted January 9 Report Posted January 9 If modern manufacture then the DC motors are likely to have permanent magnets for the field so they will be polarity sensitive. Small 6v DC motors are also available on Amazon. I wonder if you could match up the physical size of the 12v DC motor in the heater you are considering with a 6v DC one. . . Quote
