Contact Continuity Test
Depress the plunger at the bottom of the solenoid
switch. Check for continuity between the “B” and
“M” terminals using a multimeter (Figure 10-25).
The multimeter should indicate continuity.
If the multimeter does not indicate continuity,
replace the solenoid switch.

Pinion Clutch Assembly
Pinion Clutch Assembly Inspection
Manually rotate the pinion clutch assembly in the
drive direction. It should rotate freely in the drive
direction and is locked by turning it in the opposite
direction (Figure 10-26). Replace the pinion clutch
assembly if the results are different.
Figure 10-26
Slide the pinion clutch assembly on the shaft
(Figure 10-27). It should slide smoothly on the
shaft. 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.
