Question 69Electricity & Electronics - QMED

The correct answer is C) raise the no-load speed setting of the governor. When the governor control switch is moved to the 'raise' position, it will increase the no-load speed setting of the governor. This means the alternator will run at a higher speed when the engine is not under load, which in turn will increase the voltage output of the alternator. The other options are incorrect because: A) Raising the governor control switch would not affect the percentage of speed droop, which is a measure of the alternator's voltage regulation. B) Lowering the no-load speed setting is the opposite of what occurs when the switch is moved to 'raise'. D) Lowering the percentage of speed droop is also not the effect of raising the governor control switch.
