SECTION 2 - BATTERY CONDITION METER DIAGNOSTICS
Battery Condition Meter LEDs Ripple Left to Right/Steady Display
Symptoms:
The LEDs ripple from left to right, then alternate with a steady display.
When the joystick is moved, the speed setting indicator flashes.
Diagnosis:
The Dynamic joystick (1) has a short between pins 2 and 3 on the off-board charger/programming socket (connector 1a).
This safety feature will keep the power chair from operating when an off-board charger is connected by shorting out
these two pins.
Solution:
Use the following procedure to find the source of the fault:
1. Ensure there is nothing plugged into the off-board charger programming socket (connector 1a).
2. Turn the controller power off, then back on.
— If the battery condition meter LEDs still ripple left to right then alternate with a steady display, then go to the next
step.
3. Unplug the run plug (10) from connector 2b. See diagram 2.
4. Measure resistance across pin 1 and pin 4 of the run plug (10), then across pin 3 and pin 4. See figure 12.
— If the multimeter indicates less than 1 ohm for both tests, then replace the Dynamic joystick (1) and retest the system.
— If the multimeter indicates an open on either test, then replace the run plug (10) and retest the system.
PROHIBITED! Never use an extension cord to plug in your battery charger. Plug the charger
directly into a properly wired standard electrical outlet.
PROHIBITED! Removal of the grounding prong can create an electrical hazard. If necessary,
properly install an approved 3-pronged adapter to an electrical outlet having 2-pronged plug
access.
Left Red Battery Condition Meter LED
Flashing
Symptoms:
The Left Red Battery Condition Meter LED is flashing.
Diagnosis:
The battery voltage to the Dynamic power module (2) is
low. This is most likely due to batteries that are not getting
charged properly or at all.
Solution:
Use the following procedure to find the source of the fault:
1. Measure voltage across pin 1 (B+) and pin 2 (B-) on connector 1a. See figure 2.
— If the multimeter indicates less than 18VDC (but not 0VDC), then go to step 8.
— If the multimeter indicates 0VDC, then replace the Dynamic joystick (1) and retest the system.
— If the multimeter indicates greater than 18VDC, then go to the next step.
2. Plug connector 11b into connector 1a (see diagram 2) and then plug connector 12b into a standard electrical outlet.
