SOLUTIONS GRADED PLUS
◉ What is the required over current protection distance for AC
generator conductors?
Answer: A and B (7" or 40" if properly sheathed)
◉ What is the most likely problem if the oil pressure gauge needle
moves to the right when the sensor wire is grounded?
Answer: A bad sensing unit
◉ Where should you connect the volt meter leads to test voltage
drop to the cranking motor?

while cranking)
◉ What is the minimum conductor size for a lightning protection
system according to ABYC?
Answer: 4 AWG
, ◉ What is a probable cause for malfunctioning electronic
components during engine cranking?

circuit with four bundled conductors?
Answer: 10 AWG
◉ How much current should flow through the DC grounding
conductor in a 25 amp DC motor circuit?
Answer: 0 amps
◉ What should a technician do when abandoning old wiring?
Answer: Fold back, insulate and label the ends of the old wire
