As soon as I turn on the ignition switch on my 2008 Nightrain I keep "blowing" the turn signal/brake light/horn fuse. I spent the last 4 hours checking for shorts and couldn't find anything. This started happening "out of the blue"; I haven't made any modes on this bike in over a year. Any thoughts?

 

I have seen burned out bulbs short when the filament falls and makes a connection where it shouldn't. Simple test to pull the bulbs and see if the fuse stops blowing.... Just a thought....

 

LED turn signals & brake lights...thanks for the idea though

 

There's a short in the system somewhere. Start with doing maintenance on the switch... clean and regrease with electronic grease. If that doesn't do it... start working your way back to the battery from each of the parts serviced by that fuse... I use a voltmeter with needle points.

 

have you pulled the seat? the wires to the tail lamps are not protected thru the fender hole. if the harness get slack it kets the connector fall inside
