Battery Connection Test
1. Check that the female VR2 Bus plug on
the chair has voltage. Set the meter to DC volts
and measure pins 4 (using the red lead of the
meter) and 1 (using the black lead of the meter)
as shown in (fig A1.1.1)
If the voltage meter reads full voltage, then
replace the joystick module
1.1.1
1.1.2
2. If the voltage meter reads zero voltage
measure the corresponding pins on the VR2
controller as shown in (figure 1.1.2).
If the voltage reads full voltage at the motor
controller, then replace the remote cable.
Troubleshooting: No Power (cont.)
1.1.3
3. If the voltage meter reads zero at the motor
controller, then measure the battery harness
connector as shown in (fi gure 1.1.3). If the voltage
meter reads full voltage at the battery harness,
then replace the Motor Controller.
