While the 12v positive side connects straight to the indicator bulb, it is the grounding path and neutral light switch that baffles most. On nearly every motorcycle we support you will find the neutral light switch under the chain cover, a spot that also sees more dirt and grime than anywhere else on the motorcycle. This exposure to dirt often leads to a malfunctioning neutral light switch. Fortunately, simple cleaning and testing can most often resolve any issues you might be having with this switch or other parts of the circuit. In this video, we are going to help you understand the basics of the factory Honda neutral light circuit wiring and how to individually test each component to discover what is at fault and what works as it should.
