help troubleshooting blown fuse
I'm not very good at troubleshooting electrical issues so I could use some help. I was riding home the other night at dusk and I lost my headlights. When I got home and investigated, I found that my fusepanel relay kit had blown the main 30 amp fuse. I also have the eastern beaver light switch relay kit and it is powered through the insea 6 circuit fusepanel , which is why I lost my headlights. None of the fuses in the fusepanel had blown and there are 4 active circuits with fuses from 5 amp to 15 amps. (Headlights, GPS, Gerbing Connector and Aux lights). All of the fuses in the fusepanel are much smaller than the main fuse that blew. Of the items routed through the switchbox, only the headlights (15 amp fuse) were active when the fuse blew. I put a new 25 amp fuse in the fusepanel relay kit, just to make sure the original fuse wasn't defective and it worked for a couple rides, then it also blew.
This would lead me to believe that the problem is between the battery and the fuse panel in the fusepanel relay kit. I pulled the fuse panel relay kit and there are no signs of shorting on any of the wires or chafing of the wire insulator and nothing looks/smells like it arced. I figured blowing a 30 amp fuse might leave some noticable signs. My only guess is that maybe the relay is the problem.
Here is the product in question:
30A Single Circuit Fusepanel Relay Kit:
Any thoughts or ideas how I might further troubleshoot the problem would be greatly appreciated.
