A ground wire group of three wires that comes from a bundle that includes a gaggle of wires that plug into the ECU had been wrapped with tape by the previous owner. It looked suspicious to me, so I pulled off the electrical tape and one wire had been hot enough to melt the insulation. I don't know if the routing and grounding of these wires was as originally done, but it was combined with two other wires and grounded on one of the bolts that fasten the ECU to the frame. One of those two wires was a trio of brown/black/white that came out of this harness together, the other ground was attached to the receptacle for a scan tool and the third is the dodgy one. All three, as said, were ganged together after they exited the harness. I'm wondering if anyone might know what device the suspect wire traces back to. I fear it is the Doomsday Machine and I've put everyone at risk, within a certain radius, so it's an altruistic query, but no, really it's more about help in assuaging my deer-in-the-headlights countenance as I peeled it back, even now as I write this. I studied the wiring diagram printed in the manual, it was fun to look at, at first, but my confusion scaled up exponentially.
I'm thinking another ground could be run from the source. The other wires in the harness were not affected and the other two grounds were fine. The moto operated without hiccup or malfunction despite the monster in the box. And it looks as though the damage to the ground wire was from some time ago, not ongoing.
There are two pix, one is the aftermath of my chewing through the wiring harness, like a beaver. The other is the happy domicile of the hornets before I kicked it. okay, only one pic, it won't let me upload the other postage stamp-sized image. I'll see if I can include it in a reply.
Thanks in advance, any help is greatly appreciated.
