    S250 brakes lock up

    Hi Josh, I think an important thing to do, which is what many on here first suggested to me, is to check what codes the machine is throwing out when you experience the lock out. Now, I assume the lockout your experience is the abrupt locking of the parking brake, bringing the machine to a...

    Bobcat 863 lap bar spring installation

    Oh, and I forgot to add for anyone else doing this, that after you have installed the pin and retaining clip for the yoke, you have to loosen the allen bolt and return the spring tension to the same amount as the other side. For a reference, I just checked the distance the bolt protrudes through...

    Bobcat 863 lap bar spring installation

    Okay, I got the spring and sensor back in place tonight. I tried first to use some metal wire, but I found it kept spreading too much and so the spring wouldn't fit. Now the wire I used was some old general purpose spool I had from Home Depot, so maybe not proper mechanic's wire, and that's why...

    Bobcat 863 lap bar spring installation

    Thanks for the tip, Crewchief. I tried a variety of installation methods, always just barely missing it. I read somewhere else someone trying to drift the yoke for the spring in position and then push the pin in, but I'm worried about breaking the plastic switch behind it, should something...

    Bobcat 863 lap bar spring installation

    Hello everyone, I'm trying to reinstall the spring for the seat lap bar. I had to take out the seat bar switch to test it, and at the time it seemed I had to remove the spring, as well (though I'm not sure if there was a way around that). Anyway, it seems like it should be simple enough to do...

    Bobcat 863 G Intermittent Seat Light and lockout

    Okay, I pulled out the rubber seal/boots on the back of terminal connector J2, and with it plugged into the controller and the key on, I probed the orange wire, which should be the power supply (return switched power from the ignition) into the controller. I am getting 12+ volts going into the...

    Bobcat 863 G Intermittent Seat Light and lockout

    Okay, at the engine oil sensor, I'm getting the same readings, about 3.5 volts. I didn't bother checking the other sensor, as I can't lift the cab inside my garage, and I didn't want to deal with oil pressure sensors shutting me down. Anyway, so I'm getting less than half the necessary voltage...

    Bobcat 863 G Intermittent Seat Light and lockout

    Okay, thanks for the information. I was wondering if there's 8 volts at the other sensors that that means the controller's okay. So, that's good to know. I'll check that next. Still not sure what to make of the ~4 volts on two of the seat switch wires, if you're supposed to treat both as INPUT...

    Bobcat 863 G Intermittent Seat Light and lockout

    Willie, do you mean there's a bypass kit for the seat lap bar sensor, or do you mean for the sensor that goes underneath the seat? As far as I know, I only have the sensor for the seat bar. Joe

    Bobcat 863 G Intermittent Seat Light and lockout

    Crewchief, I did a bit of reading on Hall effect sensors, and I determined that at the seatbar switch, the wires 3900, 3920, and 3910 represent the Input voltage, Output voltage Signal, and ground respectively. I tested these wires at the seat switch connector to a chassis ground. Ground wire...

    Bobcat 863 G Intermittent Seat Light and lockout

    HeyMccall, Thanks for the picture. No, my machine doesn't seem to have the seat switch. Maybe mine's a later model (1999, though), or perhaps original owner removed, I don't know. Either way, thanks for the picture to confirm. Crewchief, regarding the sensors, is it possible I am missing...

    Bobcat 863 G Intermittent Seat Light and lockout

    Crewchief, at this point, do you think there is anything left to check? I thought I remember reading someone said that one bad sensor can throw the others off, but not sure if that's the case here. If the magnet is working on the seat switch, and it's in alignment, that switch should be fine...

    Bobcat 863 G Intermittent Seat Light and lockout

    An update on the machine. Even though the traction lock solenoid got very very hot yesterday, hot enough to melt the plastic wire sleeve a bit, the fuse did not blow, which was surprising. I took the relay out and tested it, and it seemed to be open and okay, so maybe freed itself (or problem...

    Bobcat 863 G Intermittent Seat Light and lockout

    Thanks, Willie, for the detailed break down of how the traction solenoid works. I appreciate the information a lot. Aside from the main controller itself, could there be any related issue that would cause both the pull coil relay to keep getting signal when it shouldn't and also the controller...

    Bobcat 863 G Intermittent Seat Light and lockout

    Hi Willie, There's no seat sensor, just the seat bar switch, sorry if I was unclear. As far as codes, I was getting "NONE" every time the seat bar light would not come on, which was intermittent. A few times, though, I would get the traction lock beeping and flashing light, and the code was...
