Prevent damage to the (PG VR2) power module. Be careful when touching the leads on the
power module. Do not allow the meter leads to touch each other, which will cause a short.
6. Reconnect the power harness to the power module. Disconnect the bus cable from the power module.
Measure voltage across pin 1 (+) and pin 4 (-) on the bus cable.
•
Greater than 24VDC - Replace the power module.
•
0VDC – Go to the next step.
7. Reconnect the bus cable to the power module. Disconnect the bus cable from the joystick.
Measure voltage across pin 1 (+) and pin 4 (-) on the joystick.
•
Greater than 24VDC - Replace the bus cable extension.
•
0VDC – Replace the control unit.
Before attempting to measure resistance, make sure there is no power to the circuit.
8. Disconnect the 2 white circuit breaker wires from the batteries. One labeled (+) positive terminal on one
battery and the other labeled (-) negative terminal on the opposite battery.
9. Measure Resistance across the terminals on the circuit breaker.
•
Less than 10 ohms – Go to the next step.
•
Open – Replace the circuit breaker.
10. Check continuity across the circuit breaker wires. Remove the positive (red) terminal and the negative
(black) terminal wires from the batteries and check continuity across each wire. Replace wires as necessary.
SCENARIO 3: Batteries Will Not Charge (Battery Box Charging Test)
NOTE: Battery chargers will not charge the batteries unless the battery voltage is 18VDC or above and there is
a closed circuit between the batteries. The circuit breaker completes that circuit.
Make sure that the circuit
breaker is reset.
If necessary, use a set of known good batteries.
1. Check the voltage across pin 1 (+) and pin 2 (-) on the charger XLR connector.
Note: The charger must be plugged in and turned to the on position.
•
Greater than 24VDC – Go to the next step.
•
Less than 24VDC – Try another wall outlet or known good charger.
Do not touch either of the multimeter probes on the third pin or the XLR connector cover.
You may damage the charger.
2. Remove the seat and the battery box cover by removing the 9 screws on the underside of the battery box.
Note: The battery box must be installed to perform the following testing procedures.
3. Make sure that the batteries are connected according to the battery connection diagram on the inside of the
battery cover and/or on page 21. Check the batteries and cables for corroded or loose terminals. Clean and
tighten if necessary.
