Troubleshooting is done on a faulty battery tray. The steps to determine if a battery tray is faulty and how to
troubleshoot it are as follows:
When a battery tray is received from unit maintenance, inspect it for damage. Repair any damage
before proceeding with testing. See section IV if repairs are necessary.
Verify the symptom. Perform the operational check found in paragraph 15-11. This will direct you to
the correct troubleshooting flowchart or identify the fault.
Troubleshoot the battery tray using the flowchart. It will identify the defective module or component.
Replace the defective module or component. Follow the procedures in section IV.
Verify the repair. Repeat the operational check in paragraph 15-11 that failed. If it passes, then
continue with the rest of the operational check. When the operational check is passed, the battery tray
can be returned for use.
The flowcharts provide views of the battery tray test points. These test points are used to fault isolate to a
defective component. See figure 15-2 for the overall layout.
