Replacement electrical wires
« on: February 14, 2024, 06:48:39 AM »
Any ideas on where to buy wire with the proper colouring, ie. green with red stripe.. to restore original wiring?

New wiring harness might be a better bet. Hard to rebuild an old harness. For example, where mine went up to the headlight it was very stiff and crispy.

Get a used/hacked wire harness and solder and heatshrink, as long as you are good with soldering.....
I've bought a couple of parts bikes that harnesses were compromised that were good for cutting and splicing, which I've done on a few harnesses.
On my K8 I used another harness from another K8 frame, both harnesses had problems at opposite ends, so I staggered cut the wires in the center after removing the tape covering.
If I get around to bringing those other bikes without a harness back to life I'll buy a replacement harness.

Dwayne…., I have two or three harnesses I pull apart whenever I need a bit with a specific colour and end. You’re welcome to them. J.

Might take you up on that. Right now I am putting the engine back together so a while to get to the switches.

That's a great link. Do you know how the wiring gauges run- what gauges would be needed for say a low duty wire/a headlight wire/ a main fusebox feed wire?

That was my first thought was that they have 22 gauge wire which I bet would be fine for that purpose. A quick google told me 150-200 mA is what the coil in a relay typically draws. A coil that ohms at 72 ohms would have that amperage draw.

Anytime. I need to return your engine stand and have one side cover too. Looking for anything else? I can post you a harness anytime. J.

18awg would be my recommendation to carry that current. 22awg I reserve for ground wires from momentary switches as an example. It might rate as suitable, but it’s so much smaller than stock it becomes a bit of a nuisance for integrating to the stock loom.

I misunderstood, I thoght he was asking about the signal wire for a headlight relay.

I just meant generally, what different gauge wires should we use for the different levels of load of our sohc4s electrical components

Indeed, and it is fairly popular to put loads such as headlights on a relay so that the switch has an easier job :-). Having the correct color of a smaller gauge wire just for activating the relay would be cool :-).
