I've got a 2001 I/S that has a headlight problem that came on suddenly that I can't seem to figure out. Without warning I lost both high and low beams along with the high beam indicator light. Everything had been working fine until this with both high and low beams functioning normally. All other functions of the bike (turn signals,horn,audio system,speedo,fuel gauge) are working properly which I would think rules out a ground problem .
The first thing I did was check the bulbs,then the fuses and all is good there. So next I thought it had to be either the headlight

switch or the headlight relays. I had an extra switch and a set of relays so I first tried the new switch and no change. I then changed out both the high beam relay and the low beam relay and still no worky. I have checked the fuses with a test light and they have power going through them but no juice at the headlight plugs . I even swapped out the headlight sub harness in the fairing to see if there was a problem there but same results. I've pretty much tried everything I can think of and have run out of things to try.
Am I overlooking something simple here or has anyone else experienced this kind of problem? It seems to me like I have read something on here in the past about a connector in the harness in front of the battery box that others have had corrosion trouble with that caused some kind of intermittent problem but couldn't find any info on it when I did a search. Any idea's would be appreciated.
Thanks,
Dana
