Good day, I ended up with a 2017 Cub Cadet Challenger 700 as part of a farm machinery trade (buy two wagons, get a broken UTV for free). Long story short, the owner had put about 1500 hours on it running tap lines in his sugar bush, and when the rear driveline went out of it he lost interest in working on it anymore . I have it together and running, but the wiring harness to the oxygen sensor burned off in such a way that it isn't possible to tell which wire goes to the pigtail coming out of the sensor (The plug was completely burned up. The sensor had somehow come out and the harness laid across the muffler and melted the plug). The wires in the harness are green/black, white/black, light green, and grey. The wires coming out of the oxygen sensor are purple, white, black, and grey. If anyone has one and could look to see which colors match it would be greatly appreciated. The local dealer couldn't help, as the wiring diagram in the service manual does not include the oxygen sensor circuit. Many thanks in advance. Leon

First time poster - new member. Most issues between my pioneer 700 and Challenger 700 I’ve been able to fix without issue. This problem is a different story. Have a 2016 Challenger 700 that overheated due to cooling fan not coming on. Changed both temp sensors on thermostat housing as well as radiator temp sensor. (Being that unit overheated I teplaced to be safe) Put power to fan to verify operation - works great. Checked all fuses, connections ect. No issues found. Verified coolant level and air bled out - all good. Using a temp gun I Can see temps climb to 210 at thermostat housing and 195 at rad at sensor location and fan won’t turn on. Any help on where to check or any wiring schematics for this unit ?

Hello and new to this forum. My 700 series cub cadet just quit running while driving. It will turn over but nothing happens. The display doesn’t come on. I have checked fuses and they all look good. I’m not a mechanic and really don’t have the spare cash to take it to the rip off dealership that has a bad name. I had just moved into town and didn’t know this. Anyway not sure where to start after checking fuses. I did have the battery checked and it heck’s fine. Can anyone suggest a possible solution?
