Conductance testers are used to test all of the following EXCEPT_________.

A) current flow
B) batteries
C) starters
D) generator output

Conductance testers are primarily used to measure the ability of a component to conduct electricity, which is directly related to its ability to store and deliver power, such as in batteries, starters, and generators. They do not directly test current flow, which is the movement of electric charge, but rather the capacity for such flow.
