Are you using the original heater switch? It is set up to run the field and armature current in series and in low adds a resistor to the series. So the voltage across the field or armature winding is always less than 6 volts. When testing the motors, I have run 6 volts in parallel with no negative effects. The motors usually burn out when stalling (no back emf increasing the current and melting the sh*llac insulation), or when the sh*llac insulation gets old and breaks allowing a short to increase current. So if you are using the variable resistor two prong heater control, don't run the windings in parallel.

I have done this and gotten away with it, just by running the fan at the lowest speed. Or you might put a voltage reducer in the circuit, or find a 12v fan motor that will fit your heater.

Can you safely run 12 volts into a 6 volt heater without causing a lot of grief in the long run? The 6 volt motor really responds to 12 volts. Tom
