Re: Electrical cut-out R1100RS tipped to left

My son had a R11S and it had nearly a total melt down of the wiring going to the back half of the bike.?? The bike seemed to not have enough fuses ( it only has 4 fuses).??? The adjacent wiring in a wire bundle would over heat, melt the insulation off and then fuse to the wire next to it.? No direct short thankfully but as you would suspect brake lights would stay on since they were getting power from other circuits, turn signals didn't work or caused other lights to blink, it was a crazy mess solved ony by peeling most of that factory electrically tape wrapped wiring bundles and splicing in new ( and better) wire.???? 

I never did find out the original source of the trouble since by the time I found it half of all the wires were fused together,

I don't know if the RS suffers the same fate but check your wire bundles carefully you may be looking only at the tip of the iceburg...

Have you checked the sidestand switch? That would be an obvious options as it is on the left side and would cause the same symptoms.?
