Bit of an odd one but any thoughts appreciated... Standard indicator setup on 850 mk2. Engine off and at idle the indicators work fine. When actually riding the left indicators will usually not work (not come on at all). Rights have never been a problem. Coming to a stop the lefts will usually start working again. Obvious issue is a dodgy connection somewhere so I've jiggled all the wires in the headlamp shell and around the rear light bracket. Stationary (tricky to check riding!) I'm getting low resistance from the indicator housings back to battery. Jiggling the switch when riding doesn't help either. Indicators have standard setup with earth through the bodies. Any words of wisdom?
