starter terminal B (4).
3. Remove the starter from the engine.
4. Disconnect the connecting lead (3) from the starter terminal
C
(2).
5. Connect a jumper lead from the starter terminal S (1) to the
battery positive terminal post.
6. Connect a jumper lead momentarily between the starter terminal
C (2) and the battery negative terminal post.
7. If the pinion gear does not pop out, check the magnetic switch.

[5] ENGINE STOP SOLENOID
Functional Check
1. Remove the engine stop solenoid (2) from the injection pump.
2. Connect the leads as shown in the figure.
- Connect the jumper leads from terminal P through the switch
(4) to the battery positive terminal
- Connect the jumper leads from terminal H through the switch
(3) to the battery positive terminal
- Connect the jumper leads from the negative terminal to the
engine stop solenoid body
3. When switch (4) is turn ON , the plunger is pulled into the solenoid
body and then turn OFF the switch (4), the plunger comes out.
4. Turn on the switch (3) then turn ON the switch (4), the plunger is
pulled into the solenoid body and it is kept in HOLDING position
