Q & A

What's in the Box

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. 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.

Reducer works very good on 6 volt blower

September 15, 2014
I have used this 12 volt to 6 volt reducer on many wiring jobs in cars and trucks , updating them to a 12 volt wiring harness but keeping some original things like the heater with a 6 volt blower motor. I have also used on old 6 volt radios. And anyone using ANY resistor reducers must keep in mind they can get very HOT .... so follow instructions and install as directions suggest.
Pros:
  • not many choices for this application and it works
Yes, I recommend this product.

Worked Great

Not much to say other than is worked great with no complaints. If you don't install one in a 6 to 12 volt conversion your blower motor will spin lie crazy and I'm sure it will eventually burn out.
Yes, I recommend this product.

Excellent heavy duty product!

September 11, 2011
I purchased this unit to reduce the voltage from 12 volts to 6 volts for the heater motor in my 1949 Ford F1 pickup restoration project. It was easy to install in the heater shroud (for cooling). I recommend it over the bulky round units that attach to the dash.
Pros:
  • Performs well
  • Excellent quality
  • Well built
  • Looks good
  • Easy To Install
Yes, I recommend this product.

Will it power a 6 volt horn? I have a vintage 6 volt horn I'd like to use in my 12 volt car. Will this handle the current draw?

Answers

EricM
This 6 volt reducer would be the correct unit for your vintage horn. It will handle 10 amps of current draw and if your horn is in good condition should be fine. As with many vintage parts current draw could exceed the original specifications and would be up to checking current draw as to lifespan of the reducer.

Answers

LED lights have an extremely low amp draw. This would not be the right type of voltage reducer for lights. You should use the Runtz reducers 91064101 for your LED lights. The 23 watt rating may even be an incandescent equivalent and not necessarily the wattage of the LED. LED's are very commonly advertised that way.

You can wire this voltage reducer either direction. Connect the 12 volt power feed to one side and the other end will output 6 volts.

Can I use this reducer for a 6v starter solenoid on a system converted to 12 volts Keeping the 6 volt starter in place, however I want to protect the solenoid by keeping the the solenoid close to 6 volts to prevent damage. This is a Auto-Lite starter on a 1953 Chrysler 251 flathead powering a Tucker Sno-Cat.

This 12 volt to six volt reducer is recommended for voltage reduction from 12 to 6 on an item that is motor driven or requires more current draw than a simple gauge. This reducer will handle up to a continuous 10 amp current draw such as blower or heater fans or even the older tube style radios. To verify compatibility you will need to verify actual amperage draw of the Pertronix coil. These DO need to be mounted in an area that allows for air movement so the reducers ribbed aluminum body will be allowed to dissipate the heat created during use.

For gauges such as oil pressure, water temp, and fuel Speedway recommends the Runtz reducer number 91064101.The heavy duty reducers are for fan motors and the old 6 volt radios which had high current draw on start up.

Mount it after the switch. I mounted mine just before the blower motor with a duct outlet blowing over it to keep it cool.

This reducer for fan motors, early tube radios, and anything with higher current draw mounts before the motor and if the motor is controlled by the switch it mounts before the switch. In the early 6 volt switches many were a rheostat style switch and the windings would be damaged if mounted ahead of the reducer at the power lead.

This Runtz reducer is used on heater blower motors to reduce the voltage from 12 volts to 6 volts when converting a 6 volt vehicle over to 12 volts and is not intended for use on fog lights. I am sorry we do not have a reducer to work with fog lights.
