Check Procedure 4 - TOW/RUN switch
Please refer to Chapter 1 “Protection for Electrical Safety”.
1. Use a multimeter, set it at diode testing position, connect the black (-) probe to one connecting
terminal of towing switch and put the red (+) probe on the connecting terminal on the other side.
2. When TOW/RUN switch is on position RUN, the multimeter should show a conducting state. When
TOW/RUN switch is on position TOW, the multimeter should show a disconnect state.
3. Check the continuity of the other group terminals with the above mentioned method.
4. If the continuity reading is not correct, replace the TOW/RUN switch.
Check Procedure 5—Battery voltage
Please refer to Chapter 1 “Protection for Electrical Safety”.
1. Before starting this check procedure, connect the battery properly and charge it fully. Use a 48V
battery discharger. Connect the positive electrode (+) wire to the positive binding post of Battery 1
and connect the negative electrode (-) wire to the negative binding post of Battery 6. Write down the
voltage reading of the discharger.
2. Turn on the discharger and record the voltage reading of the battery at under voltage.
3. For a fully charged battery in good condition, the reading should be lower than 41 at under voltage.
4. A reading of 41V indicates a discharged or faulty battery. Each battery should be checked in under
voltage state with a multimeter.
5. Don’t start the discharger if the voltage is lower than 41V. If the battery voltage is lower than 41V, it
indicates the battery is completely discharged or faulty.
6. Record the voltage reading of the battery pack in under voltage state allows a more accurate
diagnosis on battery condition. When the discharger is started, it will result in battery pack under
voltage, repeated operations are helpful to determine the failure of one or more batteries in the
battery pack. The voltage of the battery not measured at under load may not show the actual
condition of the battery. For more information on battery, refer to Chapter 11 “Battery and Charger”.
Check Procedure 6—Circuit check for key switch and accelerator pedal switch
1. Disconnect the battery cable according to the directions. Please refer to Chapter 1 “Protection for
Electrical Safety”.
2. Check the key switch.
3
．
Remove the middle instrument panel. Refer to "Key switch removal" in Chapter 9.

．
Use a multimeter set at 200
Ω
; connect the red (+) probe to the key switch terminal connected with a
red wire. Connect the black (-) probe to the other terminal of the key switch.
