Or go for the Runtz 12v to 6v voltage
Thanks Maxx

if you want to run a 6 V gas gauge on 12v, use a 30 ohm 2 watt resistor. The gauge uses around .2 amps and that works out to 1.2 watts on the resistor. | | |

Because the dash gauge...your fuel gauge for example runs on just a quarter of an amp and a resistors trypically have a 40 percent
varation in voltage depending on the electrical load that is a lot to a gauge that runs on just a quarteer of an amp. By contrast a Runtz is a solid state device that puts out te correct voltage regardless of the electrical load. Thanks Randy | | |
