On the last trip I took, the headlights were cutting in and out randomly. Not sure the cause - they would work for 10 miles, then cut out or vice versa. The inner two lights always stayed on but don't provide that much light. The outer two I think should always be on, whether you are on high or low. Those are the two that were cutting in and out. Starting the sled up this weekend the outer bulbs aren't coming on at all. We tried working through as much of the wiring as we could, checking for frays, bad connections, dirty connectors. Tried working through the wiring the best we could with a voltmeter. Couldn't find anything. The sled does have the updated voltage regulator. Any ideas? Is there a relay somewhere that I should check - I didn't see one. Planning to ride on Thursday but not sure what to do next.
