Contact Continuity Test
Depress the plunger at the bottom of the magnetic
switch. Check for continuity between the “B” and
“M” terminals using a multimeter (Figure 11-23).
The multimeter should indicate continuity.
If the multimeter does not indicate continuity,
replace the magnetic switch.

Pinion Clutch Assembly
Pinion Clutch Assembly Inspection
Manually rotate the pinion clutch assembly in the
drive direction (Figure 11-24). It should rotate
freely in the drive direction and is locked by turning
it in the opposite direction. Replace the pinion
clutch assembly if the results are different.
Figure 11-24
Slide the pinion clutch assembly on the shaft. It
should slide smoothly on the shaft (Figure 11-25).
Rust, too much grease or damage could prevent
the pinion clutch from sliding smoothly. If the pinion
clutch assembly does not slide smoothly, clean the
shaft and pinion clutch assembly or replace the
damaged component.

Ball Bearing Inspection
Rotate each ball bearing while holding the pinion
clutch assembly (Figure 11-26). Replace the ball
bearing if it does not rotate smoothly or has
excessive play.
