250-500cc Electrical Gremlin

Ive got an electrical gremlin in my 13/WR300 in that the engine will sometimes quit when the lights are on.usually I just turn it off and she will fire right up.I dont want it to not fire up when Im a long way out bush so its time to do something about it
The rear light is pretty shaky too I wonder if rocks have been pulverising the wiring under the rear guard.
anyone else replaced wiring?

Not replaced but repaired on many bikes, sounds like its earthing out to the frame some where just look for signs of damage, on my 360 the loom got mashed between regulator and fork leg.
So re moved indicator wires and repaired the ones with damaged insulation.

Ok kool thanks

Hope it's not the ignition. Seems several guys have had issues with the Ducati ignitions slowing dying. Not enough power to run the lights and provide spark to the engine at the same time.

Theres no lights at all now so I reckon Itll be easier to find the prob. She runs fine though

Your regulator still hooked up? I had green wire break at night during a ride everything went ultra bright for a second then I was thrown Rudley into the darkness with no light.
Took out both bulbs with extra volts

I got a light kit and a harness made by R. Lang in Ontario. The harness was pretty simple, I am sure it will not take you more than 20 bucks to make it yourself. I got mine for $75 if i remember correctly. Now my brake lights don't work and the rear light fixture has come apart and getting light fixture hanging from the wires. Good luck!!

no looks like the loom get mashed against the fork leg - couple of broken wires and of course they are the same colour so not sure which goes where. One from the switch and one from the light - both yellow and black

That's fine then I think they are all joined with crimps some where that will be a common feed.
I re-routed mine higher and put the clamp for the loom up instead of down.

Keep looking you may find more

that all makes sense thanks juicypips

and yes i found another damaged one

All fixed yay !

Score, you re route the wiring loom so it doesn't pinch in an off?

Yes I will, just repaired wires but still to tape up wiring and re route

(plenty of offs on my 300)

thx again

No problem, we are here to help.
Well I try to anyway.

That's how I re did my loom, notice how thin it is now I removed the indicator wiring. There's alot of shared wires there.

Yeah looks slim my 300 has a box maybe a regulator? that connects to the horn in there as well
Mine is well outta the way of damage now tho
