6v heater in 12v car who's running one

All the cool old heaters are 6v. can you run a reducer and be good to go? need a heater in my daily driver 41 ford

 

I didn't even run a reducer. fan just goes a little fast.

 

I ran one on my 37 p/u. Didn't run it on high, no problems.

I ran mine on 12 volt - as said it ran fast. I always figured when it burned up I'd replace the motor then - still waiting.

 

you should put reducers on the switch, one for each speed, for best operating results.

 

The original 6V heater has been running in my 54 Ford with a reducer from Speedway for 4 years with no problems.

 

6v heater with reducer, works great.

 

hi ive been running 6 volt heaters for years just put a reastat switch in that adjusts the speed and keep warm it works fine sal randa

 

I've been running a high wattage resistor between the switch and heater motor on both my daily rides. One for 14 years now and never had any problems.
A resistor/reducer should be used. The small resistor across the heater switch for medium and low settings is not large enough for 12V main voltage.

A cheap $15 reducer from Speedway will be all you need .

54 Chevy, no resistor. not much heat air flow out of it either. But no problems.

 

6v blower in my 50 chevy 12v system for 10yrs no resistor, goes like hell defrost works great and will run you out in 20degree weather, I say hook it up and don't sweat it (no pun intended)

 

I got two resistors from Napa and run an old 6V Firestone heater with a rheostat switch. Works like a champ.

 

I recommend a resistor or reducer. That one posted in a picture a few posts up is the type I like best.

Even if you are willing to live with an over-speeding blower motor, you need to take into account that they sometimes throw off of the armature windings when they run too fast.

If that happens you could suddenly end up with a cold car or possibly even smoked wiring.

I remember long ago, we would often put in a blower motor from a 12V car very easily.
I suppose you could still do that today. I would imagine that parts stores still sell the 12V versions that easily mount in the old heater.

 

Here is my question then - If I hook my 6VDC heater motor to 12VDC, would it work better with a 12VDC rheostat, or with a 12VDC on-off switch (or a off-lo-hi switch)??? Since you guys have had good luck running yours without a stepdown voltage relay, what works best?

That switch, mentioned above for $14.95, looks like the solution to me. I'm trying to go cheap, but don't want to fry my car, either.

 

Remember that a voltage reducer works by increasing resistance in the circuit When you increase resistance, you produce heat. Those resistors can get pretty hot, so be careful where and how you mount them, as they can be a fire hazard if you're not careful.
