## What gauge is Harley Davidson wiring?

OEM cables are 6 gauge welding cable. Welding cables will carry more current that just a stranded cable would .

## What gauge are ignition wires?

You’ll typically find 16-gauge wiring carrying current to the ignition coil, from the generator to the starter — on cars so-equipped — interior lights, parking lights and tail lights.

## What type of wire is used on motorcycles?

## How do you determine wire gauge size?

To calculate the gauge of stranded wire, you’ll need to double the diameter. So, if you’ve measured a wire’s diameter to be 0.005 inches (0.127 mm), multiply this value by itself. The result will be 0.000025 in (0.000635 mm). Multiply the result by the number of strands in the wire.

## How do you determine wire size?

Wire is sized by the American Wire Gauge (AWG) system. Wire gauge refers the physical size of the wire, rated with a numerical designation that runs opposite to the diameter of the conductors—in other words, the smaller the wire gauge number, the larger the wire diameter.

## What is the difference between 2 gauge and 2 0 gauge wire?

2 AWG will handle around 94 Amps, while 2/0 AWG will handle around 190 Amps. The length of the wire must be considered as well as the % voltage drop in order for this to be true. For a 3% drop where the load is less than 20 feet from the battery and you are drawing 100 Amps, you would need 2/0.
