Bobcat Headlights giving me problems!!!!

    OK, need help on this one.

    Machine: 2001 Bobcat 863G
    Hours: around 3300hrs

    Here is my deal:

    My headlights will only turn on and off if they feel that it is a good time for them. You can press the button 1000 times, and only on the 1001st time will the lights turn on. The next time, on the 6th time, they will come on. Next time, 100 pushes.

    Here is what I have tried:
    Checked the Fuses
    Checked the Relays
    Swapped the overhead panel out with a known working panel out of another machine

    But I can tell you this. The other night, we were moving snow and I had to have the lights, so here is what I did.

    I popped out a headlight, took a wire from the 12v+ on the headlight plug of the harness, and applied 12v+ from the battery to it. The other headlight light came on, as soon as I removed the 12v+ the light shut off. So I re-applied the 12v+ to the plug and reached in and pressed the headlight button 2 times. This caused the other light to turn on and the rear lights to turn on. I pluged the light that I had pulled back in and we worked the rest of the night. When it came time to load up, I didn't want the headlights on on the trailer, so I tired to push the button to shut the lights off and they wouldn't even shut off.

    Now, before I get a bunch of you have a bad 12v+ power to the button responces, I understand that it is most likely that. I have enough knowledge to reverse the power from the battery and back feed the lights to get them on in a pinch. I understand electric. I need a little help figuring out where to even start looking in the loom to find what wire is bad.

    And, if it is a bad 12v+ to the switch, why would all the other features like the "bucket positioning" "high flow" "variable and max flow" buttons work just fine??

    Any help would be great.

    Yes, I would check the connections for either being corroded or loose first. Chances of a wire just going bad are slim, unless they are rubbing or pinched.

    I fixed it by selling the machine and buying a new cat machine.:dizzy:
