4.24 Checking engine stop solenoid

IMPORTANT
• Never apply the current for pulling coil more
than 2 seconds when inspecting.
1. Remove the engine stop solenoid from the engine.
2. Connect the jumper leads from the pulling coil P
terminal to the switch (4), and from switch (4) to the
battery positive terminal.
3. Connect the jumper leads from the holding coil H
terminal to the switch (3), and from switch (3) to the
battery positive terminal.
4. Connect the jumper leads from the engine stop
solenoid body to the battery negative terminal.
5. When switch (4) is turn on, the plunger pull into the
solenoid body and then turn off the switch (4), the
plunger comes out.
6. Turn on the switch (3) then turn on the switch (4),
the plunger pull into the solenoid body and it keep
in holding position after turn off the switch (4).
