LS180 problem. Gradually gotten worse

LS180 problem Problems

I have a problem with my New Holland LS180 that has gradually gotten worse. It started with the seat belt light flashing and progressed to stay on. I unbuckled my seat belt and re-fastened it and it worked for a while. Today, after I had run it for about ten minutes, the light came on, so I turned it off and tried to start it again, but it wouldn’t come on.

After fiddling with it for a minute, it started but as soon as I moved the pen, the seat belt light came on and blocked the pen. This happened a few more times before I gave up. I had a replacement hydraulic pressure switch, so I replaced the one on the machine. That did not solve the problem. When this problem started I checked the seat belt and seat switches and they were fine. Is there anything else I need to check?

LS180 problem. Gradually gotten worse

I had a similar problem on an older New Holland LS 180 Skidsteer. The problem was that the belt coupler was worn out. This allowed the seat belt tab to not always activate the switch on the belt coupler. I replaced the coupler and everything was fine. Check the coupler by disconnecting it. Now sit on the seat as usual. While sitting on the seat, thread a wire through the harness to the seat switch. Now turn on the machine and see if the arm works. If it does then you know you need to replace the belt coupler.

Even though you may think you are not moving when you use the pedals, you are actually shifting your weight slightly on the seat. If you have a suspended seat, raise the seat and pull the wires that go into the wire connector for the seat switch. If one of them comes off, which is where they usually fail, then you’ve found your problem.

There is also the possibility that the seat switch itself is too sensitive to weight movement. Before doing the following, lower the boom and turn off the engine. safety first. To check the seat switch disconnect the seat switch connector, bridge the two terms of the seat switch harness connector. When you do this, the instrument panel will light up. Lower the seat, sit in it, and fasten your seat belt. Now try raising your arm. If it works, the problem is the seat switch. You can also check the seat belt by jumping between the two terminals of the seat belt harness connector. By doing this you should be able to locate your problem. This is safety equipment for your protection and all bypassed switches MUST be reconnected.

I think I have found the problem. While I was testing the seat switch again, I noticed that it opened when I moved in the seat. Thinking the switch was intermittent, I removed it from the seat and tested it through several cycles. The switch never failed to complete the circuit. I reinstalled the switch in the seat and it couldn’t keep the circuit closed when I moved slightly on the seat. Turns out, even though the seat was adjusted for my weight, it wasn’t firm enough to keep the switch on. I have raised the knob to make it firmer and the switch now appears to be working properly.
