4. Measure voltage across the battery negative (black) terminal and the battery positive (red) terminal.
•
Less than 18VDC – Load test and replace batteries as necessary.
•
Greater than 18VDC – Go to next step.
•
0VDC – Go to step 9 on page 11.
5. Measure voltage across pin 1 (+) and pin 2 (-) on the battery box charger port located on the outside of the
battery box.
Note: The battery box must be removed to perform the following testing procedures.
•
Less than 18VDC – Load test and replace batteries as necessary.
•
0VDC – Check in-line fuse for continuity.
Before attempting to measure resistance, make sure there is no power to the circuit.
If the fuse is bad (open), replace with the
exact type and rating fuse
.
If the fuse is good (short), check the battery box charger port wires for continuity.
Troubleshooting Guide for the VR2 Power System
Step 1: Battery voltage is always the first thing to check.
A. Check the battery voltage through the 3-pin battery charger port located on the front of the controller as
shown in figure 1.
Set voltmeter to the 50 VDC scale.
Place the meter leads into the two outside pins of the battery charger port as shown in figure 2.
Meter should read approximately 25 VDC.
B. If the voltage is below 25 VDC:
Recharge the batteries for 8 hours.
Check wiring for any visible damage and make sure all the cables are connected properly.
Make sure that the pins are seated in the connectors properly and the fuses are good.
C. If the voltage is 20 VDC or less:
The battery charger may not recognize a low voltage and thus will not charge the batteries.
Boost charge the batteries to bring the voltage up to a level that the charger will see, then plug the battery
charger into the charger port and charge for 8 hours.
If the batteries will not charge, replace both batteries.
