Section 1
Troubleshooting: No Power
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.
Note: Make sure the polarity is correct. If polarity is
reversed proceed to step 1.5
1.2 Test Joystick
1.1 Circuit Breaker Reset
A1.2.1
IfOn/offbuttonispressed andnolightor barisshown,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.
A1.1.1

1.3 Battery Test
Check that the batteries are fully charged and in good
workingcondition.Remove theseat andbattery cover.Usea
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.
A1.3.1
If the voltage meter reads below 12 volts, charge the batteries.

1.4 Battery Connection Test
Check that the female VR2 control cable has voltage. Un-
plug joystick from control cable. Set the volt meter to DC
volts and measure the voltage using the red lead in port 1
and the black lead in port 4 as shown in (figure 1.5.1.)
A1.5.1
A1.5.2
If the voltage meter reads approximately 24 volts, then
replace the joystick. If the voltage reads 12 volts or less,
measure the corresponding pins on the VR2 controller as
shown in (figure 1.5.3.) If the voltage meter reads full volt-
age, then replace the jumper cable.
If the voltage meter reads approximately 24 volts, replace
the control cable. If the voltage reads 12 volts or less then
proceed to measure the voltage from the battery harness
plugging into the controller. If the voltage measures approx-
imately 24 volts, replace the controller. If it reads 12 volts or
less proceed to the next step.
If all of the measurements read full voltage, then replace the controller.

Troubleshooting: No Power (cont.)
1.6 Check Battery Wire Harness
Check that the battery wire harness has the polarity cor-
rect. Set the meter to DC volts and measure the voltage
with the red lead in the white connector and the black lead
in the black connector as shown in (figure 1.6.1.) If both
wiring harnesses have approximately 12 volts and polarity
is correct, replace the main battery harness plugging into
the controller. If voltage is less then 10 volts proceed to
section 1.3. A1.6.1
If polarity is reversed correct battery wiring.
If the meter reads more than one ohm, change the Battery harness.
1.5 Circuit Breaker Test
To check the circuit breaker, remove the left rear shroud
by unscrewing the two Phillips head screws (figureA1.8.1).
Set the meter to ohms and measure the resistance or
check for a “tone” (continuity). If you are not getting a
“tone” or the resistance measures more then 1 ohm, re-
place the circuit breaker. If meter gives a “tone” or resis-
tance measures less then 1 ohm, proceed to next step.
A1.8.2
If the meter reads more than 1 ohm, then change the circuit breaker.

Troubleshooting: No Power (cont.)
If the previous steps did not correct the problem, check the
main harness. Disconnect the main harness from the front
and rear battery harness. Check the continuity between the
white rear connector (figure 1.9.1) and the black front con-
nector.
1.7 Main Harness
A1.9.1
A1.9.2
A1.9.3
Next check the continuity between the black rear connector
(figure 1.9.2) and the left contact on the controller plug.
Next check the continuity between the white rear connector
(figure 1.9.3) and the right contact on the controller plug.
If the meter reads more than 1 ohm in any of the above
tests replace the main harness.
