Long story ahort, my friend brought me a 2015 48 that wouldn't srart.
Seems that in an attempt to change the handle bar, the wires were wedged flat by the handle bar grip clamp... on both sides.
which made sense to me looking at two fuese were blown were at ignition and accessory.
I've un-did the clamp and sure enough all the cables were flattened out. When I inspected it with my eyes it didn't seem like any insulation rubber was broken.. yes they were very flattened but no broken rubber.
So my question is, can a group of wedged / flattened wire still cause a short and course the fueses to blow, without breaking the rubber?
The wires can open inside the insulation, yes, but shorting requires metal/metal contact somewhere. Since the fuses were open, that would indicate a short. If you've absolutely ruled out the flat spots (which should be repaired or replaced regardless) then look for a short in another area, or consider something was allowed to short during installation.
It's possible that when the wires were crushed, they shorted against the handlebar or clamp. Look closer, the insulation might be thin enough in the damaged area, otherwise it's like Red said, you have a short elsewhere.

thanks for this. I will have a very very closer look tonight. I got a feeling they may have shorted against each other as the black outter rubber has no damage.
anyway here's a photo from the top.
For the fuse to blow, it has to come against a ground. Just a broken wire will not blow a fuse, nor will a "flatened" wire. As stated above if the insulation has broken through, and is touching a ground, or a ground wire, or if the wire is a ground, and touching a fused powered wire, a fuse will blow. Did you replace the fuses, after the clamps were loosened? Did the fuses blow again? Did you wiggle the wires, and did the fuses blow?
Did you extend the wires for the switches to change the bars?

No. It has to make contact with an opposing wire. (positive or negative)
Or a chassis ground

They simply can break apart and not conduct current. About the same result as a short.
Analize. They worked before being crushed and don't after. What is the mystery?
My lack of knowledge is the mystery! Lol

The fact that the wires were flattened means they were stressed. More than likely they were pulled in one direction or another which could mean the far end could have had tension place on it resulting in connector pins backing out and touching (momentarily or otherwise.) Perhaps too where they were flattend could have been against a small sharp edge like a burr or flake of chrome making a tiny insulation puncture momentarily to ground. A cheap ohmmeter or continuity tester is your friend in chasing out open or shorted wires.
