one of the four switches
The first step in a diagnostic strategy should always be: - Answer Verify the customer concern
A diagnostic strategy is - Answer Based on logic and a repeatable series of steps
To diagnose a circuit problem when you don't have a symptom chart you should: - Answer
Have the wiring diagram for the circuit
A true of a delta-wound stator - Answer There is no neutral junction
Alternating current in a generator is rectified by: - Answer Diodes
Automotive generators with three stator windings generally use how many diodes? - Answer 6
diodes
What is the field winding of an automotive type generator part of? - Answer It is part of the

What do voltage regulators regulate? - Answer They regulate the voltage that an automotive
generator produces
Generator output is directly related to: - Answer Field strength and rotor speed
Most voltage regulators operate in the range of: - Answer 13.0 to 15.5v
To properly check for parasitic drain - Answer Ammeter in series
Internal voltage regulator are: - Answer Unserviceable and must be replaced if defective
, A generator drive belt in poor condition and not tensioned properly - Answer Undercharged
battery and squealing noise after the engine started
As battery voltage drops during cranking, current flow: - Answer Increases
Relays can be tested for: - Answer Proper resistance across the solenoid coil and a voltage
drop not exceeding 0.2 volts across the contacte

A starter relay is used to: - Answer Complete the circuit between the battery and starter
solenoid
Starter solenoid performs two jobs for the starter motor - Answer Engage the drive
mechanism and close a switch between the battery and motor terminals
As the starter motor armature spins, its speed is controlled or limited by: - Answer The CEMF
and mechanical loads
Describe the internal resistance in a starter motor - Answer The resistance is very low
