Message: <blockquote data-quote="thetool" data-source="post: 17247" data-attributes="member: 1534">If you can drive it with the left handle it is an SJC machine, but you can't, so it's not, so alrighty then........=).A yellow button on the handle indicates that it is the latest gear so that's not a problem.On the handle, if you pull the rubber boot up, you can see an assembly with a plunger.  That is the potentiometer, or "sensor" as Bobcat calls it.  The bottom is through-bolted to the fixed part of the handle, and the top or plunger side it boted to the pivoting handle.  moving the handle runs the plunger in and out of the body, which generates the signal for the servos, or "actuators" on the control valve, all run the the controller on the machine.If the bolts or pivots on the handle are loose or out of alingnment, you will get your code, because when in neutral, the handle sensor may not be in what it thinks the neutral should be, and it has to be there on power up for safety.  It's programmed like that so your boom or bucket don't  move when you start the engine.I don't know what they did when you say they recently replaced the handle.  If they replaced the whole handle, it should be okay.  If they only replaced the handle sensor, it's easy to screw up the alignement.  The holes for the pivots get egged out.  Stuff like that.  Or they could have replaced it with a faulty part.  How long ago did they fix it?  You could have a parts warranty issue.  They could have misdiagnosed it and replace the handle when you really have a controller problem.Additionally, even with these problems, it sounds like you got a good deal on the machine, and I see why you got it.</blockquote>
