Switch to 12v

In layman's terms, as one decreases the voltage, the amperage increases=more heat.

On a cmp one will find mostly 14g wire with 12 g and 10 g wire where required.

On modern vehicles, most of the wiring is 18 g or lighter as 12v requires only lighter wire to carry the amps.

You may find that the battery cable size on modern vehicles to be about a 6 gauge while the older 6v is around a 2 or 3 gauge.

Ever notice if you go to purchase a set of battery boosting cables that the higher end ones are quite expensive and a heavier quality? That is because the heavier cables carry more "juice" than their lighter ones.

For the technically inclined, amps= watts / volts

What about R....???

Watts(POWER)
=E X I

I(Amperage)= E(Voltage)/(Over) R (Resistance)..


I always used welders stinger cable on wiring the heavy 6 or 12V stuff..It is very flexible and properly designed(Braided) to carry high amperage..
