4. Measure the resistance of the coil in the solenoid
using an ohmmeter. Connect one meter lead to
the case ground and one lead to the tab terminal.
If the resistance is 5.2/6.3 ohms, the coil is OK.
ELECTRIC STARTER
If the resistance is low or 0 chms, the coil is
shorted. Replace solenoid.
if the resistance is infinity ohms, the coil is open.
Replace solenoid.

Figure 8-17. Bendix Drive Electric Starter.
BENDIX DRIVE ELECTRIC STARTER
The M18 & M20 engines will use either a Bendix drive
starter as shown in Figure 8-17 or a solenoid shift
type starter described on pages 8.16 through 8.21.
Operation - (Bendix Drive Type Starter)
When power is applied to the starter, the armature ro-
tates. As the armature rotates, the drive pinion moves
out on the splined drive shaft into mesh with the fly-
wheel ring gear. When the pinion reaches the end of
the drive shatt, it rotates the flywheel cranking the
engine.
When the engine starts, the flywheel rotates faster
than the armature and drive pinion. This moves the
drive pinion out of mesh with the ring gear and into the
retracted position. When power is removed from the
starter, the armature stops rotating and the pinion is
held in the retracted position by the anti-drift spring.
NOTE: Do not crank the engine continuously for more
than 10 seconds at a time. If the engine does
not start, allow a 60 second cool-down period
between starting attempts. Failure to follow
these guidelines can bum out the starter
motor.
