Q & A
What's in the Box
"Runtz" transistorized reducers allow you to use your original 6 volt electronic devices (like gauges) on a vehicle that has been converted to 12 volts. You will need a "Runtz" for each 6 volt electric gauge on your car.
Designed for 12 volt negative ground systems only. Screw type terminals. 1.5 ohm resistance, 4 amp max load, 25 watts.
910-64101 Instructions (PDF)
Note: Never, ever use ceramic block style reducers for gauges, radios or lighting. A power surge will destroy the electronics when first turned on. Ceramic block reducers should only be used to operate 6 volt DC motors and fans on 12 volt DC.

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.
