2013 Bonneville Starts When Clutch Pulled In

A breakthrough, I thought to myself what changes overnight and bingo, when I turn the bars to the left to put the steering lock on it malfunctions and starts on clutch pull, straighten the handlebars as I did last night to move it and it works correctly on the starter button. Repeated it 4 times, full lock to the left starts on clutch pull, handlebars straight starts on button. I can only think something in the wiring in the headlamp is shorting, don't think it is the starter switch anymore as when I did this the starter switch was hanging off as I'd taken it off the handlebars, so don't think the starter switch was impacted by handlebar movement. Looked in the headlight and can't see anything obvious, might still be the starter button cable moving but unlikely as hanging free, so maybe something the other side of the connector it plugs into in the headlight. Anyway, far too electrical for me. Might have to see if I can get someone to come out and look at it.

 

Thanks, but don't think so as it does actually start, just not from the button.

 

It all looks fine, can't see any obvious damage anywhere, grommet looks good but not much room, would be a nightmare trying to feed out the existing starter button cable with the connector on it. Bit messy looking but all electrics look messy to me. If I turn handlebars to the left, switch ignition on and pull in the clutch the headlight dims, bike starts and headlamp comes on full. I'm too chicken to try pulling in the clutch again though.

 

I gave it a quick check but very difficult to see it clearly. The wiring from the starter switch just goes directly into the headlamp and doesn't really touch the headstock at all. I'll give it another look in the next day or 2. The starter switch itself is hanging loose off the handlebars and when I turn the handlebars it doesn't seem to move the cable at all, but there must still be some slight movement in the grommet even when hanging loose.
Thanks

 

Thanks for all the advice.
It does go into another connector and I did check that and it also looked ok. I'll give it a more thorough look in the next day or so, work permitting.
Cheers

 

Switch all felt fine, very positive return when pressed.

I tried lifting the main wiring harness away from the headstock as gently as I could, no worn paint or wires that I could see. However, now the issue has gone so I suspect a wire within that harness may be the culprit. I've booked it in with an independent mechanic in Chesham to have a look. Unfortunately, by accidentally fixing it I may have made it harder to diagnose.
