If only one side of the fuse lights with a test lamp, the fuse is:

• good

• blown

• close to failure

• shorted to power

These components are designed to fail if a circuit has excessive current and must be replaced in this situation:

• fusible links

• relays

• connectors

• circuit breaker

A faulty circuit could have no continuity or:

• high amperage

• high resistance

• low resistance

• high voltage

This component should only have current in only one direction:

• fusible link

• fuse

• relay

• diode

A standard automotive battery will have _____ cells.

• 2

• 4

• 6

• 8

When removing an alternator, what should a technician do:

• Ensure the battery terminals are connected

• disconnect the positive battery terminal

• disconnect the negative terminal

• completely remove the battery

if voltage decreses and resistance stays the same in a circuit, what will happen to amperage?

• it will increase

• it will decrese

• it will stay the same

• it will be the same as resistance

Resistance measurements are typically used to to check vehicle __________.

• components

• brakes

• amperage

• batteries
