heater motor

[oldcarlover]

I just converted my 36 ply. to 12 volts. Where can I find a 12 volt heater

motor that will fit into the unit like the original 6 volt. Also, can I use the

original switch with the 12 volt motor?

A forum search should net you the answers to your questions.

I put a 12volt to 6 volt reducer on my 38's heater...

I did the same with my 36 Plymouth. I mounted a ballast resistor on the outer firewall away from anything flammable (did the same on my 52 Dodge truck). The original switch is working fine. I even have a 6V rubber bladed fan mounted to the steering column on that same fused circuit. I did the conversion several years ago-no problems with accessories in either vehicle. Mike

I am contemplating this too, I can either go the voltage reducer route for the 6 volt heater box for my 12 volt 55 Fargo pickup.

But are they safe and reliable, will they get too hot.

I am either going this route, or I will try and find a 12 volt blower motor to fit into the heater box.

I need to find a 12 volt motor similar in size to this motor from my heater box.

As I suggested do a forum search. I just did and found this.

I also did the forum search, and found this pic posted by Blueskies.

Although that heater motor looks very similar to mine, the mounting studs on mine are at the opposite end of the motor. Not sure if those motor case screws can be reversed or not....

I'm in the same boat with a 6V blower motor needing to go to 12V. Did a lot of research and found a few places and may try a few motors. Good Luck on your hunt and let me know which one works if you get one done.

Thanx TP, 1st site has almost the identical to my motor, but its 12 volts, may go that route.

Heres a test I did today, Tim Adams also has posted results of a similar test.

On the bench I used a ignition coil ballast, not sure how many watts there rated at, but wired it to a 12 volt battery, then connected to my 6 volt heater motor, it got very warm in a few minutes.

I did not do an Amp reading, but in order touse a ballast, it would have to be pretty beefy for a heater motor. Mind you, heaters are used in cool/cold weather, so possibly it would not be as critical, as if the same motor was sued for AC in hot weather.

I have found a 50 watt 12 to 6 volt reducer, for $10.95, if it works, the price is right.

I don't think there are to many voltage droppers that work that great with heater motors, if someone wants to refute this, and tell what they did, I would appreciate it........
