Are there any other wire harness grounding points other than the green wire at the reg/rec? The diagram in the manual didn't show any other that I could see. I'm aware of the battery ground to the engine. Ive just discovered my low fuel light when on, flashes off when the turn signals are on. It seems the turn signals are either stealing power or ground from the low fuel light. The turn signals function properly,when the signal flashes on the low fuel light goes out,when the signal flashes off the low fuel light comes back on. I had to add enough fuel to get home which turned the low fuel light off so the level sender seems to be functioning. I'll ride until the light comes back on so i can do more testing.

 

I think I remember seeing something resembling a ground near the thermostat. For the temp sensor maybe?? Idk though. Never investigated it.

 

There are a total of six notable one's and a few minor... The best way to know what's going on in the harness, is to click the link in my sig and download the colored wiring schematic...
