I have one and had to do a little repair on it. The wiring is very fragile and the motor requires oiling periodically. After seeing the guts, I wouldn’t put 12 thru it. It would be cheap and easy to wire in a transformer.https://www.ebay.com/itm/12-Volt-to-6-Volt-Voltage-Reducer-Heater-Blower-Motor-Voltage-Reducer-6V-wiper/171695758294?hash=item27f9dd5bd6:g:WV4AAOSwQJhUjOWk

Can’t begin to tell you how much I hate the name Stovebolt.
