2. Measure the resistance with an ohmmeter across
the B terminal and the G terminal, across the B
terminal and the ST terminal, and across the B
terminal and the ACC terminal.
3. If 0 ohm is not indicated, these contacts of the main
switch are damaged.

4.3 Starter
4.3.1 Checking motor
CAUTION
• Secure the starter to prevent it from jumping up
and down while testing the motor.
(1) C terminal (2) Connecting lead
1. Disconnect the battery negative cable from the
battery.
2. Disconnect the battery positive cable and the leads
from the starter.
3. Remove the starter from the engine.
4. Disconnect the connecting lead (2) from the starter
C terminal (1).
5. Connect a jumper lead from the connecting lead (2)
to the battery positive terminal post.
6. Connect a jumper lead momentarily between the
starter motor housing and the battery negative
terminal post.
7. If the motor does not operate, check the motor.
4.3.2 Testing starter magnet switch (pull-in,
holding coils)
IMPORTANT
• Testing time must be 3 to 5 sec.
(A) To negative terminal
(B) To positive terminal (C) C terminal
(S) S terminal
1. Remove the motor from the starter housing.
2. Prepare a 6 V battery for the test.
3. Connect jumper leads from the battery negative
terminal to the housing and the starter C terminal.
The plunger should be attracted and the pinion gear
should pop out when a jumper lead is connected
from the battery positive terminal to the S terminal.
4. Disconnect the jumper lead to the starter C
terminal. Then the pinion gear should remain
popped out.
4.4 Glow plug
4.4.1 Checking glow plug lead terminal
voltage
1. Disconnect the wiring lead (2) from the glow plug
(1) after turning the main switch OFF .
(1) Glow plug (2) Wiring lead (Positive)
2. Turn the main switch key to the PREHEAT position,
and measure the voltage between the lead terminal
and the chassis.
