Wire Gauge

[Brad_G]

Does anyone know the size of wire used for the lighting system such as turn signals etc. It would appear maybe 20 gauge but not certain so I thought I'd ask.

No info in either of my manuals as far as gage, sorry can't help.

Thanks for the link. There were some additional good resources in there.

Your welcome, yes I bookmarked a few myself.

I think you are close on the gauge of wiring for the turn/brake light wiring system. Any wiring that I do in that circuit, I'll use 18 or 16 gauge wiring.
For Head light and driving lights, I'll use 12 or 14 gauge wiring.

Thanks for your input Duke and roadiemort.

The metric motorcycle wire is real hard to tell what gauge it is. We don't have an exact replacement for it so you just get as close as you can. Careful judicious use of a wire stripper go from the larger to a smaller setting until you hit wire is the way I normally do it, best I can always guess is it's 17 17 gauge bigger than 18 smaller than 16.

Brad having replaced the headlight socket, and done a LOT of other wiring on the 02, I found the wiring is as close to 18 gauge as it can be. It is just an r c h under but closer to 18 than 20 gauge.

Thanks for the input. I think I'll do 18 when I rework my rear signals. Will probably opt for 16 when I do the converter and 4-way flasher mod.
