I have a question regarding setup of the throttle position sensor (part #3131591) which is used on virtually every Polaris CFI sled. When setting the voltages should I expect the voltage to remain fairly stable when tightening the screws? I have one which will jump by .02 volts with no perceptible movement of the actual sensor. Baseline setup is .70 plus or minus .01 volts so according to that it jumps out of that range. I don't think this is normal but wanted a second opinion from those who have actually setup the unit. Anyone else ever run into this problem? Sensors are $240 here so I am hesitant to buy one just on spec.
