Auxiliary Fuse and Power Connector
Many GL's have an auxiliary fuse and power connector located under the
rider's seat. This switched power source is available for powering aftermarket
accessories and is unconnected from the factory. It is mentioned here because
folks new to troubleshooting GL's sometimes become concerned that something may
be missing.
Unconnected Flasher Wire
Another source of unnecessary concern is the green wire located next to the
flasher. This wire is not used and normally hangs loose.
Conclusion
Hopefully this brief introduction to motorcycle electrical troubleshooting will be helpful in diagnosing many of the more common problems, particularly for the CX/GL models. If you need further assistance please post a request on the Honda CX500 and GL500 Forum.
