Magnet Switch Test
1. Disconnect the battery negative cable from the battery.
2. Disconnect the battery positive cable and the leads from the
starter
M
terminal.
3. Remove the starter from the engine.
4. Disconnect the connecting lead (1) from the starter
C
terminal
(2).
5. Connect a jumper lead from the starter
S
terminal (3) to the
battery positive terminal post.
6. Connect a jumper lead momentarily between the starter
C
terminal (2) and the battery negative terminal post.
7. If the pinion gear does not pop out, check the magnetic switch.
NOTE
• This test should be carried out for a short time, about 3 to
5 seconds.

Starter Relay
1. Open the panel board and remove the starter relay.
2. Apply battery voltage between terminal
2
and
4
, and check for
continuity between terminal
1
and
3
.
3. If ohm is not indicated, renew the starter relay.

(6) Glow Control System
Glow Plug Lead Terminal Voltage
1. Disconnect the wiring lead (1) from the glow plug (2) after
turning the main switch off.
2. Turn the main switch key to the "
PREHEAT
" position, and
measure the voltage between the lead terminal and the chassis.
3. Turn the main switch key to the "
START
" position, and measure
the voltage between the lead terminal and the chassis.
4. If the voltage at either position differs from the battery voltage,
the wiring harness or main switch is faulty.
