Nine Bars - Solenoid Brake Trip
Battery Fault
Check that the batteries are fully charged, the
correct voltage and in good condition. Take a
voltage reading from pin 1 and pin 2 of the charger
port of the VR2 controller, see (figure 3.5.2) If the
meter reads more than 30 volts, then check the
charger. Otherwise, replace your controller.
Ten Bars - High Battery Voltage
An excessive voltage has been applied to the
control system. This is usually caused by a
poor battery connection. Check the battery
connections.

The parking brakes have a bad connection.
Check the parking break and motor connections.
Make sure the control system connections are
secure. Measure the two small contacts on the
four-pin motor connector (fig 3.5.1). If both motor
connectors read approximately 60 ohms, then
replace the controller. Otherwise replace the
motor that does not read approximately 60
ohms.
3.5.1
Controller Fault -
A control system trip is indicated. Make sure that all connections are secure. Check that the
batteries are fully charged and in good condition, and check all joystick connections and cables. If this does not
correct the problem, disconnect the power to the controller for 2 minutes, replug in to reboot the module. If the
condition still exits, then replace the controller.
