Gear shift sending unit .1980 gs1000g
 

Can anyone tell me if the gear switch sending unit that is displayed on the head light console could cause my bike not to get fire ? The neutral light isn't on so I'm wondering if this could cause it not to fire. I'm in the last stages of a rebuild and couldn't afford a new wiring harness so mine is a bit chopped up. There are a few wires leaving me scratching my head .
