Speedway Motors 91064103 Details

This voltage reducer allows the use of an original 6 volt heater blower and switch in a vehicle converted to 12 volts. Safer and much more reliable than the less expensive ceramic type voltage reducers. Compact 1" x 1" x 3" size occupies little space. 12v to 6v reducer works with up to 10 amps of continuous current draw.

Note: This reducer generates a fair amount of heat when in use. It should be mounted to a non-flammable object, preferrably near cool moving air while the vehicle is in operation.

Overall Assessment

Product reviews highlight its confirmed features and qualities as a reliable voltage reducer in vintage automobiles. Customers commend the product's practicality for retro conversions, particularly for 6-volt gauges, wiper or blower motors, radios, and horns, in various car models like a 1949 Ford F1 pickup, a 1951 Chevy pickup or a 41 Dodge. The product's usability shined in reducing voltage effectively, without compromising the component's function. Its easy installation was a plus. Notably, its small compact design eases its fitting into various vehicles. However, users noted that it may generate heat during use and it's sensible to consider this during installation. The longevity and material quality of the product were yet highly appreciated, making it a popular choice over competitors.

I use this in between the heater switch and blower motor on a 54 Pontiac. It's been converted to 12 volts and it works great.

Works well to drop the voltage from 12 to 6 volts so I can run my original 6 volt heater fan motor and switch in my 51 Chevy pickup. It generates a fair amount of heat so I am mounting it on an aluminum heat sink. The current drop with this resistor is less than other comparable units so the fan runs at the correct speeds. Overall I'm quite satisfied.

I would definitely buy this again

Used it on my 47 Fargo. Works great. It does get hot so make sure there is some kind of air flow to it.

How hot do these get? Would they burn you if you touched it? Should they be mounted away from the fuse panel and other components? This will drive a 6V heater fan in a '35 Ford so there's not a lot of room under the dash, and no ducts to mount it in.

I just bought a 54 Lincoln that has already been converted to run on 12v. Nothing else is hooked up as of yet. I've read most of the questions and answers. Will this work for the original power window motors?

I upgraded to a 12 v battery where a solenoid in place was operated by a 6 v battery to open a motor valve. I have been going through solenoids on account of the higher voltage just wondering if this may work because these solenoids are 6 volts.

I have a Chysler flathead 6 volt engine I am converting to 12 volts. It has a starter switch on the starter motor. Will this resistor work for the starter switch when the starter motor is wired to the 12 volt battery?

I was wondering if this would be the right product to reduce 12 volts to 6 volts on a windshield washer pump. I have a '66 Karmann Ghia that I am converting to 12 volts, but I am wanting to run an aftermarket electric windshield washer system, but that system uses a 6 volt electric pump.
