SECTION 1 - NO POWER
Symptoms:
The battery condition meter LEDs do not light up when the
on/off key is depressed.
Diagnosis:
There is a power interrupt in the system.
Solution:
Use the following procedure to find the source of the interruption:
1. Measure voltage across pin 1 (B+) and pin 2 (B-) of the
off-board charger programming socket (connector 1a).
See figure 2.
— If the multimeter indicates 0VDC
, then go to the next step.
— If the multimeter indicates greater than 18VDC, then
replace the Dynamic joystick (1) and retest the system.
— If the multimeter indicates less than 18VDC (but not
0VDC),
then recharge the batteries and retest the system.
2. Unplug connector 4b from connector 1b.
See diagram 2
.
3. Measure voltage across pin 2 and pin 3 on connector 4b.
See figure 3.
— If the multimeter indicates 0VDC
, then go to the next step.
— If the multimeter indicates greater than 0VDC, then
replace the Dynamic joystick (1) and retest the system.
4. Unplug connector 3b from connector 4a.
See diagram 2
.
5. Measure voltage across pin 2 and pin 3 on connector 3b.
See figure 4.
— If the multimeter indicates 0VDC
, then go to the next step.
— If the multimeter indicates greater than 0VDC, then
replace the Dynamic bus cable (4) and retest the system.
6. Remove the seat. Refer to the power base owner’s manual.
7. Remove the rear shroud. See figure 5.
