Trouble Probable cause
Starter does not start.Magnet switch does not operate.
(no clicks are heard.)Magnet switch poor contact or discontinuity
of pull-in coil circuit
Improper sliding of magnet switch plunger
Magnet switch operates.
(clicks are issued.)Poor contact of magnet switch’s main con-
tact point
Layer short of armature
Contaminants on armature commutator

Insufficient brush spring pressure
Starter starts but does not crank engine.Failure of pinion gear to engage ring gearWorn pinion teeth
Improper sliding of overrunning clutch
Improper adjustment of stud bolt
Clutch slippage Faulty clutch roller spring
Starter starts but engine cranks too slowly.Poor contact of magnet switch’s main con-
tact point
Layer short of armature
Discontinuity, burning or wear of armature
commutator
Poor grounding of yoke field coil
Insufficient brush length
Insufficient brush spring pressure
Abnormal brush wear
Starter overruns.Magnet switch coil is a layer short.
