    Notes
    Use with gauges, not heater fans or radios.

"Runtz" 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.

careful installing!

By The Monster from Oregon on 11/5/2010
Pros:
Easy To Install, Great Instructions, Simple to understand
Best Uses:
Use orig 6v gauge w 12v
Bottom Line: Yes, I would recommend this to a friend

Be careful installing this reducer. The ground wire runs very close to the mounting hole. When you run the nut down onto the reducer when securing it to the gauge, make sure the ground wire doesnt get pinched between the reducer and the nut. Mine did and it split the wire insulation just enough that it shorted and ruined my reducer. Results were no gas gauge and no turn signals. (turn signals attach at the back of my gas gauge). Also, put some duct tape or something to the back side of the reducer to cover the head of the bolt. My reducer was a hair away from my dash cluster when installed and I could imagine it flexing when going over rough terrain and shorting to the dash cluster. Or maybe put the duct tape on the dash cluster itself. Thats it! Other than that it works well, after ordering my second one! haha
