131. Gain is critical to an Electronic Speed Control system. If gain is set too low, what will likely result?

a. Speed will fluctuate wildly under no-load conditions
b. Frequency will drop too low for too long when load is applied
c. The unit will likely go into over-speed at start-up and immediately shut down
d. The unit will respond to load too quickly and go into an over-voltage shut-down

132. Magnetic Pick-ups have what type of output?

a. Resistance
b. VAC
c. Inductance
d. 4 – 20 Milliamps

133. Why is shielded wire required to carry the signal of a Magnetic Pick-up?

a. To protect the wire from engine heat
b. To protect the wire from chafing
c. To protect the signal from external noise
d. Unshielded wire is preferred due to the tight confines of the location of the pick-up

134. What is the most common failure found in mechanical governors?

a. Bearings
b. Magnetic pick-up
c. Broken wires to the actuator
d. Leaky air couplings

135. What would most likely be the problem if an Electronic governor failed to operate properly?

a. Misadjusted Magnetic Pick-up
b. Faulty CPU
c. Inability of the CPU to detect changes in resistance of the Magnetic Pick-up
d. Voltage spikes through the Magnetic Pick-up feed wire
