Test Procedure 41 - Z13 (Red Wire) and Z14 (Green Wire) Continuity
1. Turn the key switch to OFF and place the forward and reverse switch in NEUTRAL. Disconnect the bat-
teries and disconnect the Z plug from to the controller.
2. Disconnect the 3-wire plug at the motor speed sensor.
3. Place the black (-) probe of a multimeter, set to ohms (
Ω
), in the female terminal of the red wire in the 3-
wire plug at the motor speed sensor, and place the red (+) probe in the Z13 (red wire) connector posi-
tion in the Z plug (Figure 21-77, Page 21-49). The reading should be continuity. If the reading is incor-
rect, repair or replace the red wire.
4. Place the black (-) probe of a multimeter, set to ohms (
Ω
), in the female terminal of the green wire in the
3-wire plug at the motor speed sensor, and place the red (+) probe in the Z14 (green wire) connector
position in the Z plug (Figure 21-78). The reading should be continuity. If the reading is incorrect, repair
or replace the green wire.
5. Make sure that the red (Z13) and green (Z14) wires are in the correct positions in the Z plug and in the
3-wire plug. Make sure that the terminal ends are securely fastened in the plug housings.
Test Procedure 42 - Motor Sensor 3-Wire Plug Connection
1. Turn the key switch to OFF and place the forward and reverse switch in NEUTRAL. Disconnect the bat-
teries. Leave the Z plug connected to the controller.
2. Place the black (-) probe of a multimeter, set to ohms (
Ω
), in the female terminal of the black wire in the
3-wire plug at the motor speed sensor, and place the red (+) probe on the B- terminal on the controller.
The reading should be continuity. If the reading is incorrect, repair or replace the black wire.
3. Check for correct pin terminal position in the plug, and make sure the pins are securely pressed into
the plug housing.
4. Inspect for dirt, moisture, or corrosion at the 3-wire plug housing and terminal pins.
5. Make sure that the pins make secure connections in the pin receptacles.
6. Connect the two halves of the plug and make sure that the outer ring of the female plug housing snaps
securely over the notches on the male plug housing.
• IT IS POSSIBLE THAT THE VOLTAGE SIGNAL FROM THE CONTROLLER IS TOO LOW FOR
THE SPEED SENSOR TO READ. IF CONTINUITY CHECKS SHOW THE WIRES TO BE GOOD, IT
MAY BE NECESSARY TO REPLACE THE SPEED SENSOR IN ORDER TO GET MOTOR BRAK-
ING FUNCTIONS OPERATING PROPERLY.
