When performing voltage drop testing on cranking circuit components on a 12-volt chassis,which DMM V-DC range would provide accurate results?
A) 0 to 0.100 V-DC
B) 0 to 2 V-DC
C) 0 to 10 V-DC
D) 0 to 20 V-DC

Question

Quizplus · Accepted Answer

The 0 to 2 V-DC range is most suitable for voltage drop testing in cranking circuit components because it provides the precision needed to detect small voltage drops that are significant in diagnosing starting system issues, without being too broad to lose detail or too narrow to miss larger drops.
