Thanks! | | | | | Joined: Dec 2003 Posts: 1,061 'Bolter | | 'Bolter Joined: Dec 2003 Posts: 1,061 | I used the 6 Volt motor untill it burned out. If you have it apart, look around for a 12 Volt. I think I got one at a local parts store that fit , but I had to shorten the shaft a little. Better to fix it now than in the middle of a blizzard. Been ther done that.

Unlike a starter were you can use a 6V in a 12V system since it's not operated for long stretches, a blower is on for long periods and will burn out as mentioned above. I see 12V motors on ebay all the time or perhaps a small motor shop near you can rebuild yours at less expense.

Just swap to a 12V blower motor- - - -it should last for a lot of years and they're not that expensive.

No energy goes away. It can only be converted to another form of energy. The voltage drop resistor takes half of the electric energy and converts it to heat (another form of energy) | | | | | Joined: Apr 2005 Posts: 396 Shop Shark | | Shop Shark Joined: Apr 2005 Posts: 396 | My 6 volt motor lasted about 15 minutes at 12 volts. Change it now if you have heater out.

But the comment on the resistor getting hot is correct thanks to physics. | | | | | Joined: Jan 2002 Posts: 2,841 'Bolter | | 'Bolter Joined: Jan 2002 Posts: 2,841 | Today I drove around and finally turned on my heater, reaching for the resistor and dang! That pup got hot. Need to reconsider.
