Troubleshooting Guide For (Shark); Step 1: Checking Battery Voltage - Golden Technologies Compass Sport Service Manual

Troubleshooting Guide for the Shark 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.
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 as shown in figure 2. 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.
