Test Procedures
3. Turn the key switch to the OFF position and place the Forward/Reverse switch in the NEUTRAL position.
4. Test the key switch.
4.1. Remove the instrument panel. See Key Switch Removal on page 17-1.
4.2. Using a multimeter set to 200 ohms, place the red (+) probe on the key switch terminal with the blue wire.
Place the black (–) probe on the other key switch terminal.
4.3. With the key switch in the OFF position, the multimeter should indicate that continuity is not present.
4.4. With the key switch in the ON position, the multimeter should indicate that continuity is present.
4.5. If any other reading is obtained, replace the key switch. See Key Switch Removal on page 17-1.
4.6. If the key switch operates as described in the previous steps, install the instrument panel in the reverse
order of removal and proceed to the following step.
5. Test the MCOR limit switch. See following NOTE.
NOTE: Make sure that the key switch is operating correctly and that the key switch and instrument panel are properly
installed before proceeding.
5.1. With batteries connected and using a multimeter set to 200 volts DC, place the black (–) probe on the
battery no. 4 (4 x 12-Volt battery set) or battery no. 6 (6 x 8-Volt battery set) negative post and place
the red (+) probe (with insulation-piercing probe) on the green wire close to the two-pin connector on
the MCOR. See following WARNING.
WARNING
• The Forward/Reverse switch must be in the neutral position to avoid personal injury due to contact
with rotating wheels.
5.2. With Tow/Run switch in the RUN position, key switch in the ON position, and Forward/Reverse rocker switch
in the NEUTRAL position, the voltage reading should be zero volts. When the accelerator pedal is pressed,
the voltage reading should be approximately 48 volts (full battery voltage).
5.3. If the voltage reading is 48 volts when the accelerator pedal is not pressed, replace the MCOR. See
MCOR Removal on page 17-8.
5.4. If the voltage reading is zero volts when the accelerator pedal is pressed, check the limit switch circuit using
the following test procedures.
5.4.1. Using a multimeter set to 200 volts DC, place black (–) probe on battery no. 4 (4 x 12-Volt battery
set) or battery no. 6 (6 x 8-Volt battery set) negative post and the place red (+) probe (with
insulation-piercing probe) on the blue wire where it connects to the MCOR. With the key switch ON,
the reading should be approximately 48 volts (full battery voltage).
5.4.2. If the reading is zero volts, check the continuity of the blue wire that goes from the key switch to
the MCOR.
5.4.3. If the reading is approximately 48 volts, proceed to the following step.
5.4.4. Using a multimeter set to 200 volts DC, place the black (–) probe on the battery no. 4 (4 x 12-Volt
battery set) or battery no. 6 (6 x 8-Volt battery set) negative post and place the red (+) probe (with
insulation-piercing probe) on the green wire where it connects to the MCOR. With the Tow/Run
switch in the RUN position, the key switch ON, the Forward/Reverse rocker switch in NEUTRAL and
the accelerator pedal pressed, the reading should be approximately 48 volts (full battery voltage).
5.4.5. If the reading is zero volts, test the continuity of the MCOR limit switch and the green wire. If the limit
switch does not pass the continuity test, replace the MCOR. See MCOR Removal on page 17-8.
