2013 1600 GT (affectionately called Big Blue)
Experience intermittent electrical failure - no headlight, taillight, directional, horn, radio, fuel gage and gps. Fog lights and top case brakelight always work. Has to do with moisture in the air - an overnight rain or high humidity or not. Sometimes happens Sometimes not. Sometimes take it out for a quick breeze and everthing turns on - sometimes not. Can't seem to make it repeat at the dealership. Starts and runs perfectly. It was suggested that it could be a ground wire. Any insights? What is the common point for all of these systems?

My initial thought is that your left hand switchgear could be defective. Following water ingress problems, most early model bikes will have had the handlebar switchgear replaced, probably both sides, under warranty way back.

Your dealer should be well acquainted with the issue & can easily check your bike's history to clarify.

BTW, welcome along to the group - give us an intro, when you have a moment.

I think that the switches on both handlebars should have been replaced under warranty when the bike was new. Was that done? Sounds like my 2012 .
