Case IH JX1070C

Hey guys, I have a JX1070C with MAJOR wiring problems. I had a shop install the roll bar warning lights and in the process the somehow either melted or got the wrong wires or something like that and not the tractor will not move. It also keeps blowing the 15 amp fuse in position 16, which is Trailer Brakes and Hydraulic Regulations. The ECM is throwing a 49 code, which is Wheel speed sensor short to +5V or +12V. I need some ideas where to look/where to go next. The connectors almst all look good.

Sorry not up on that tractor but... reading your post. First trip is back to the shop that installed the roll bar warning lights.

That is basically a new tractor. Way newer than anything I have. If the tractor went in their shop in good running condition it should leave there the same, plus the service you paid for.

That is the problem. I am working for the other division of the same outfit that installed the lights and roll bar. our set-up shop put the lights on when the tractor came in on trade.

Ouch no fun. I am asuuming you"re an independent shop.

I looked around a couple different sites and cannot locate a schematic for your tractor. I think the 1070 is a 2003 and newer.
Heres what I would do without schematics:
1. Trace all the wires that they installed for the lights and see if they disturbed any of the factory wiring, either by cutting, chaffing, stretching etc.
2. Determine where they tapped in for power, maybe they spliced in a line somewhere that is tied to the fuse you mention in position 16, and now the circuit is overloaded.
3. Code 49 WSS short. Can"t tell you exactly on your tractor, you should be able to pin out that circuit to see if you have an open circuit or short to ground.

I have used this basic strategy more than once. Sometimes it takes a while to trace a circuit. A service manual would really help.

If I had to guess, it really sounds like when they put in the lights they may have tapped into another circuit overloading it, and possibly cut into or somehow messed up the WSS circuit.

I built an entire engine harness for my tractor after the previous owner caught it on fire. I was fortunate as the local NH dealer let me look through everything on the computer.

I know not much, but maybe that will help you where to look. Still a little amazed that tractors now have wheel speed sensors.

Make sure to post back on what you find. You have me interested now.
