After a couple of days of chasing a mystery electrical problem on our 2013 570 (fuel pump wouldn’t run) I found the culprit – the big wiring harness behind the driver’s seat had been chafing on the front engine mount. You can see the paint worn off the mount square tubing corner in photo 1.
My symptoms were loss of the fuel pump (and code 1347 5 "fuel pump driver circuit open/grounded") but it depends on how the wires are oriented when the bundle is made. I had one broken wire (the fuel pump relay ground wire from fuse box B4 to ECU Pin 219) and two others that were bared and ready to go.
The branch on the top left of the second photo is all the wires going to the ECU so all kinds of evil things could happen on the trail. As it was we had to tow it 15 km along a creek bed and cutlines with our 800 and it shortened a long weekend of riding.
It’s easy to put a couple more zip ties to the frame to keep this bundle well away from the vibrating engine mount. I’m going to go through and tightly secure all other pieces while I have the skid off.
