Dead Electrics at a stoplight! 6th Gen

the right rear turn signal won't light up off the harness.

the left Will, if I plug the right light into hte left harness, it lights. the plot thickens.

 

I'm seriously on the verge of giving up.

 

If one light is brighter than the other, the dimmer one is finding it's ground through another light or device.

 

I had a spare flasher relay laying around. turns out that is what was doing that.

bad news is, bike's still down for the count. it's going in a local shop prolly tuesday or tomorrow. ugh... insult to injury.

 

I'd start be checking every ground you can find (now would be a good time to refer to the factory service manual wiring diagrams).

Pay extra attention to any grounds that terminate on the aluminum frame or engine cases due to corrosion between dis-similar metals (steel ground wire connector mounted to aluminum can lead to excessive corrosion).
