S5-Q135.)     What would most likely be the problem if an Electronic governor failed to operate properly?

                          a.) *Misadjusted Magnetic Pick-up
                          Correct.  If the sensor is not properly positioned, it will not detect the motion of the gear teeth.
                          b.) Faulty CPU
                          CPUs rarely fail.  But when they do, all functions cease.  It would be quite evident.
                          c.) Inability of the CPU to detect changes in resistance of the Magnetic Pick-up
                          The magnetic pick-up is not a resistive device.
                          d.) Voltage spikes through the Magnetic Pick-up feed wire
                          If it is properly shielded (as required), no voltage spike should occur.

            S6-Q136.)     Referring to the transfer switch in the above figure, which control relay(s) operates with
                          acceptable utility voltage?


                          a.) LO
                          Incorrect.
                          b.) *SE
                          Correct if EA, EB, and EC were energized, system would be operational from utility power
                          source which would operate relay switches SE.
                          c.) TS
                          Incorrect.
                          d.) LO and SE
                          Incorrect.
