TROUBLESHOOTING AND ELECTRICAL
SYSTEM: PEDAL-START GAS VEHICLE
TEST PROCEDURE 6 – Key Switch (Engine Kill Circuit)
See General Warnings on page 1-1.
NOTE:
This is a continuity test.
1.
If necessary, see Testing Basics on page 18-15.
2.
Disconnect battery and spark plug wire(s).
See Disconnecting the Battery-Gasoline Vehicles on page 1-5.
3.
Remove the instrument panel.
See Instrument Panel Removal on page 4-10.
4.
Disconnect wires from the (+M) and (–M) terminals of the key switch
.
5.
Place the red (+) probe on the (+M) terminal and the black (–) probe on the (–M) terminal. With the key switch
OFF, the reading should be continuity. With the key switch ON, the reading should be no continuity. If either
reading is incorrect, replace the key switch.
6.
Connect wires to the key switch. Make sure wires are connected correctly and are tight. If they are not, rewire
or tighten as necessary.
7.
Install dash panel in reverse order of removal.

Key Switch Test – Engine Kill Circuit
TEST PROCEDURE 7 – Accelerator Pedal Limit Switch – Pedal-Start Vehicles Only
See General Warnings on page 1-1.
NOTE:
This is a continuity test.
The accelerator pedal limit switch is the top switch located in the electrical component box. There is a green wire and
a pink wire connected to this limit switch.
1.
If necessary, see Testing Basics on page 18-15.
2.
Disconnect battery and spark plug wire(s).
See Disconnecting the Battery-Gasoline Vehicles on page 1-5.
3.
Check for proper wiring and tight connections
4.
Set the multimeter to 200 ohms. Place the red (+) probe on the common (COM) terminal (green wire) of the limit
switch and place the black (–) probe on the normally closed (NC) terminal (pink wire) of the limit switch.
5.
Make sure the battery is disconnected. With the key switch in the OFF position, the Forward/Reverse handle in
NEUTRAL, and the accelerator pedal in the UP position, the reading should be no continuity. With the accelerator
pedal pressed, the reading should be continuity. If readings are incorrect, replace the switch.
