Magnet Switch Test
1. Disconnect the battery negative cable from the battery.
2. Disconnect the battery positive cable and the leads from the
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.

(2) Terminal C
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
