Glad you found it- That Miles is a genius.
Good job, but by your description you replaced only the blue wire from the ISC to the taillight.
Do you have gauge, speedo and running lights? If not, see my last post.
Cheers!
Miles your post was very appreciated. On inspection, the only toasted wires were a) the blue from the ISC to the tail- there was a blue spliced to it under the airbox that was spared, and b) the tail lights. The brown to the fuses and the main red looked good.
Any major concerns about not following the rest of your fix?
That splice that you found would be where the power is fed to the gauge lights and front running lights. I thought maybe you had not included this connection when you renewed the blue wire. But with all your lights working, guess I was wrong!
Looking at the wiring diagram, the only protection for the blue wire circuit is the main 30 amp. fuse, which may explain why this smaller-gauge wire took such a beating before the fuse finally blew. I would think a better arrangement would have been to channel the blue to the fuse box, and dedicating a 10 or 15 amp to protect it, before sending the current on it's way to the lights and taillight.
But I'm not a Yamaha engineer or an electrician, so I won't even guess as to the reason.
If the brown and red wire look good, don't worry about them.
Your problem does emphasize a characteristic of probably 80% or more of the electrical issues that have cropped up on this forum - the root cause is not devices, or the actual wiring, but connectors or splices. It's always good preventative maintenance to clean and lube with di-electric grease, any time the opportunity presents itself.
