Troubleshooting Guide for the LiNX Power System
Step 1: Battery voltage is always the first thing to check.
A. Check the battery voltage at the XLR battery charger port located on the side of the controller See figure 8.
Set voltmeter to the 50 VDC scale.
Place the meter leads into the two outside pins of the battery charger port.
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.
D. If the voltage is dropping too quickly, perform a load test on the batteries using a load tester. If you do not
have access to a load tester, you can load test by performing the follow steps.
Place the meter leads into the outside pins of the battery charger port.
Sit in the power chair and drive it.
After an initial drop, the voltage should hold steady at approximately 24VDC or higher when driving with a
load on the chair.
If the voltage continues to drop while driving, replace BOTH batteries.
