The wires appear to be in good shape. Battery is plugged in correctly. I unplugged the deans connector and got good voltage coming out of the ignition going to the sensor. How difficult is it to replace the sensor? Is there a way to test the sensor without the ignition tester? If I'm getting 5.25 volts coming out of the ignition, then that kind of points to the sensor or wires going to the sensor Right??
