Intermittent miss

Yes, LEDs only conduct one way.

Yes.
But the LED specific flasher takes power in, and sends it back out when the ignition is turned on. I tested that this morning .............  :o maybe it shouldn't and that's where the problem stems from??? Maybe it shouldn't?
Can anyone confirm?

And oddly Vince, after that point that someone told me the blinker was on (and had been for 50k's or so), was when we were stopped at the Omeo Hwy intersection to regroup before we hit Mitta Mitta. Which was when the misfire had gotten bad, bad.
 
I got nothing else to add, its all green smoke and mirrors to me.But there are a few Electrical Engineers around the Oz clubs and John Wilson is in Batemans Bay.

That sounds normal to me. It has to conduct electricity (at least intermittently) to make the blinkers work. If the blinker is coming on and staying on long enough to melt insulation off the wires, there's probably something wrong with the switch, or it's wired incorrectly.  Actually, I suspect a short circuit somewhere if wires are getting hot enough to melt their insulation. Correctly sized wires should never get that hot even if the blinkers are on continuously.

I suggest you check the indicator wiring circuits, switch, etc. Look for short circuits or something connected incorrectly.

No way Lemon, I heard that Maurice has a hump seat fitted for the trip .................. I'm not going to be that close and personal to Maurice, his past history of backing into things would have me questioning every 'accidental' bump  :-\

Meanwhile ....... back to the wiring.

Now Shaun I think that you should take your 3C with the double seat so we can share Mr K around  :D
 
Renewed, earth wire with heavy silicone sheathed insulated wire, took eart from loom to starter solenoid straight to earth with same wire.
Replaced the burnt flasher wire.

Bolted it all back together....... tested all circuits, good  :D

Hit starter button, fired up sweet and crisp.

So what was the basic cause.

Not that easy Vince, fired up good, but this morning I put my meter from battery earth post to earth lead, with ignition off .................. 12.6 fucking volts!
The only thing connected to the loom is the ign switch and the Ignitech.

 
I presume you did that test with the battery earth wire disconnected from the battery terminal.

If the ignition switch was on, you should measure something resembling battery voltage with such a test.

If the ignition switch was off, it should read zero volts, or maybe a few millivolts. No significant voltage anyway. If the meter is saying 12.6 fucking volts (where do you get a meter that swears?) then I suspect there's something wrong with the switch or it's wired up incorrectly.

It's highly unlikely to be a problem with the Ignitech box. Any current drain through the ignition system would imply that it takes its power directly from the battery - not through the ignition switch. If that were the case then the engine wouldn't shut off when you turn the key off. That's assuming the Ignitech and the ignition coils get their supply from a common feed that goes from battery - fuse - ignition switch - kill switch - ign system, or something very similar.
 
No it?s the alternator. It meters fine, but as soon as I hook up the hot wire it shows the voltage. Yet the continuity doesn?t show earthing out when I put my meter on it. Very strange.

Winkers?

Was fitting new seat last night, Thanks Steph, and what do I find ....... another short at winkers where the connectors dropped down and wore through against the rear tyre.

This rubbing was pointed out ...... just after it started missing, unfortunately thought nothing of it being a part of the misfire.

Earth wire and l/h winker wire we?re making love.
 
Had that one myself years ago,a lot of bikes have a metal conduit below the rear guard to run wiring through.Thats a big rear tyre on that bike.Tyres grow at high speed as well.
