On Sunday I was out riding and got caught in a thunderstorm, when I pulled over to change gloves I stopped the engine. When I started up again I noticed main beam light on I pressed the passing switch several times and nothing happened, it stayed on. Going about a hundred yards main beam light went out, but came on once or twice, on the way home. When I got home I though water had gotten into the handlebar switch, so sprayed WD 40 into it. Today I went to fill up with fuel for my ride out, after putting fuel in, on starting up main beam light on again stayed on till I went over a bump in the road then went out and all was back to normal. I thought wiring was just from switch to headlight, is there another connection elsewhere I should check ? anyone had this problem?
