Exam 18: Starting and Motor Systems

A cranking current test is performed, and the amperage is found to be less than specification. Technician A says the starter is bad and it should be replaced. Technician B insists on testing the resistance of the cables, grounds, and connections. Who is correct?

Identify basic guidelines for starter motor reassembling.

Checking for excessive resistance in the starting circuit is being discussed. Technician A says connecting a voltmeter across the ground cable from the battery to the ground connection of the cable is the preferred method. Technician B says connecting an ohmmeter across the positive battery cable after it has been removed from the vehicle is the preferred method. Who is correct?

The armature has two main components: the armature ____________________ and the commutator.

The teeth on a starter drive are worn excessively. Technician A says to replace the starter drive. Technician B says to check the flywheel. Who is correct?

Identify various tests used to troubleshoot the starting system.
