11) Insert the multimeter probes into the main harness connector 9a at pin 1 and pin 8 (blue wire and yellow
wire.) See figures 13 and 14. Note the resistance reading. Insert the multimeter probe into the main harness
connector at pin 1 and pin 2 (yellow wire and orange wire.) Note the resistance reading.
•
Are both readings within 500 ohms of the resistance measured in step 10? - Replace the controller.
•
Are either readings outside that range? - Go to the next step.
12) Remove the 8 screws that fasten the back tiller shroud to the front tiller shroud.
13) Disconnect the main harness (9b) from the throttle pot (14a.)
14) Insert multimeter probes into the throttle pot connector (14a) at the blue wire and the orange wire (outside
two pins.)
•
5k ohm ±10%? - Note the resistance reading and go to the next step.
•
Outside that range? - Replace the throttle pot.
15) Insert the multimeter probes into the throttle pot connector (14a) at the blue wire and the yellow
wire. Note the resistance reading. Insert the multimeter probe into the main harness connector at the yellow
wire and the orange wire. Note the resistance reading.
•
Are both readings within 500 ohms of the resistance measured in step 14? - Go to the next step.
•
Are either readings outside that range? - Replace the throttle pot.
16) Check the orange, blue, and yellow wires on the main harness for continuity.
10 ohms or less on each one? - Replace the speed pot.
Open on any wire? - Replace the main harness.
FLASH CODE #8 - MOTOR VOLTAGE FAULT (OPEN)
This Flash Code appears when there is an internal problem with the motor or its wiring.
1) Remove the seat.
2) Remove the rear shroud.
3) Make sure that the batteries are secure.
4) Lower the tiller.
5) Turn the scooter over onto its side.
6) Remove the controller cover.
7) Disconnect the front intermediate
motor harness (11c and 11d) from the
controller.
8) Measure resistance across the front
intermediate motor harness 11c and 11d.
•
50 ohms but not shorted? (NOTE:
Can be as low as 0.2 ohms.) –
replace the controller.
•
Out of that range? – Go to the next step.
9) Unplug the motor/brake assembly (12a) from the rear intermediate motor harness (10b.)
10) Make sure that the pins are seated properly on 10b. Check the continuity between 11c/11d and 10b.
•
10 ohms or less? – Go to step 17.
•
Open? – Go the next step.
11) Turn the scooter back over.
12) Remove the batteries.
13) Separate the front and rear sections of the scooter.
