defective Which technician is correct ?
3. A V - 6 is being checked for starter amperage
draw . The initial surge current was about 210
amperes and about 160 amperes during
cranking . Technician A says the starter is
defective and should be replaced because the
current flow exceeds 200 amperes . Technician
B says this is normal current draw for a starter
motor on a V - 6 engine . Which technician is
correct ?

during cranking
B)the starter produces a high - pitched whine
after the engine starts
C)the starter drive does not rotate at all
D) the solenoid does not engage the starter
drive unit
9. A technician connects one lead of a digital
voltmeter to the positive ( + ) terminal of the
battery and the other meter lead to the battery
terminal ( B ) of the starter solenoid and then
cranks the engine . During cranking , the
voltmeter displays a read ing of 878 millivolts .
