Charger Receptacle Tests
TEST PROCEDURE 23 – Voltage at Charger Receptacle Red Wire Socket
See General Warning on page 1-1.
(This procedure will determine if the 10-guage red wire used to charge the batteries has continuity.)
1.
With batteries connected and a multimeter set to 200 volts DC, place the black (–) probe on the negative post of
battery no. 8 and place the red (+) probe on the charger receptacle socket connected to the red 10-gauge wire
(3). The reading should be 48-50 volts (full battery voltage).
2.
If the reading is zero volts, check the continuity of the 10-gauge red wire from the positive post of battery no. 1
to the receptacle socket.
TEST PROCEDURE 24 – Motor Speed Sensor
See General Warning on page 1-1.
Motor Speed Sensor Test with the IQDM Handset
CAUTION
• Perform the following procedure only on a level surface. To avoid injury or property damage, ensure
that the path of the vehicle is clear before pushing vehicle.
1.
Turn the key switch to the OFF position and place the Forward/Reverse switch in the NEUTRAL position.
2.
Connect the IQDM to the vehicle.
See Plugging the Handset into the Vehicle, Section 23, Page 23-1.
3.
Access the Monitor menu and select SPEED PULSES by using the SCROLL DISPLAY buttons. The IQDM
should indicate OFF when the vehicle is at rest.
4.
While monitoring the IQDM display screen, slowly push the vehicle a short distance (about 3 feet (1 meter)). The
IQDM should indicate ON for speed sensor pulses while the wheels are in motion.
5.
If the IQDM does not indicate ON while the wheels are in motion, proceed to the following procedure, .
Motor Speed Sensor Test without the IQDM Handset
1.
Turn the key switch to the OFF position and place the Forward/Reverse switch in the NEUTRAL position.
2.
With batteries connected, disconnect the three-pin connector at the motor speed sensor.
