Troubleshooting: No Power
1.1 Circuit Breaker Reset
If On/off button is pressed and no light or bar is shown, check
for tripped circuit breaker (see figure A1.1.1) and make sure
all connections are clean and tight (including the batteries). If
the problem persists, then perform the following diagnostics.
1.2 Test Joystick
Check that voltage is going to the controller. Set the meter
to DC volts and take a voltage reading using the red lead
in pin 1 and the black lead in pin 2 of the charger port on
the VR2 joystick. (See figure A1.2.1) If the voltage meter
reads approximately 24 volts, try replacing the joystick. If
the meter reads 12 volts or less, proceed to the next step.
A1.1.1
Note: Make sure the polarity is correct. If polarity is
reversed proceed to step 1.5
1.3 Battery Test
Check that the batteries are fully charged and in good
working condition. Remove the seat and battery cover. Use a
volt meter to check the voltage across the battery terminals.
(See figure a1.3.1) The batteries should measure within 2
or 3 tenths of a volt of each other. If the batteries are not
within 2-3 tenths of a volt, load test the batteries and replace
if necessary.
If the batteries measure below 10 volts, replace the
batteries or remove the batteries and charge with a 12
volt charger. Batteries must be connected in parallel to
charge with a 12 volt charger. Connect the positive terminal
of the first battery to the positive terminal of the second
battery as well as connecting the negative terminal of the
first battery to the negative terminal of the second battery.
Charge batteries until the voltage in each battery measures
approximately 12 volts. Connect batteries back into chair
and complete charge with standard on-board or off board
charger.
If the voltage meter reads below 12 volts, charge the batteries.
