QUESTIONS AND VERIFIED ANSWERS
◉ Which of the following changes takes place to the electrical properties
of a starter circuit as the flow of amperage increases? Answer: Increase
in resistance thru the circuit
◉ Tech a says that if available voltage to a starter drops below 10.5
volts, the starter requires replacement. Tech B says that low available
voltage requires better replacement. Who is correct? Answer: Neither A
or B
◉ Tech A says that starter chatter can be caused by low battery voltage.
Tech B says that the use of an intermittent-duty relay in the starter
control circuit can cause a chattering condition. Who is correct? Answer:
Tech A
◉ Tech A says that the solenoid on the starter motor switches on and off
the high current flow required by the starter motor. Tech B says that the
solenoid on the starter motor engages the starter drive with the pinion
gear. Who is correct? Answer: Both A & B
◉ What is the most likely cause for a failure of an engine to crank, but
the starting motor turns? Answer: Defective starter drive mechanism
, ◉ Consider a starter has a "chattering" solenoid when attempting to
crank the engine. If sufficient battery current is available to the solenoid,
which of the following is most likely defective? Answer: Hold-in
winding
◉ What test instrument is best used to check for resistance in a starter
circuit when cranking? Answer: Voltmeter
◉ Tech A says that some starter motors are equipped with an over crank
protection (OCP) thermostat, which opens the control circuit when the
starter is overheated. Tech B says that the thermostat monitors the
temperature of the motor and the chassis electrical control module
inhibits the operation of the starter relay when the motor is overheated.
Who is correct? Answer: Tech A
◉ Tech A says that cranking an engine with low battery voltage causes
one of the most damaging conditions for a starter. Tech B says that low-
voltage burn-out occurs when excess amperage flows thru the starter,
causing the motor to burn out prematurely. Who is correct? Answer:
Both A & B
◉ Which of the following reasons best explains why gear reduction
starters draw less current than direct-drive starters? Answer: Gear
reduction starters rotate faster
◉ A starting motor shouldn't be operated for longer than: Answer: 30
seconds
