Hi, I am happy to have just found this website. It seems like a good place to trade info. ---- 01 863 Duetz deisel 1400hrs.---- The local bobcat dealer is guessing The wiring harness is bad. I had the machine in for service. The problem was and still is the alternater fuse btwn your legs keeps popping, anytime you run the machine at any rpm besides idle. Got the machine back from bobcat with a $500 bill and they said 2 relays were bad and that was the cause. Fuse kept popping. Brought it back to bobcat. They said the wiring harness was most likely bad and that would be $1300 for the part plus 6hrs labor. They said they could work with the existing wiring and fix any open circuts they find and repair them. They also said they put electrical grease in the fittings. Used the machine today and fuse popped 2wice!! Arrggh I just talked to them and they don't see what my problem is with them and are "seeing" if they could discount the harness at all if I want it installed. Does anyone have any suggestions for me, this is be very costly and frustrating.
