Auxiliary equipment isolation test
This test will need to be performed if the battery pack output voltage is not remaining consistent and no errors were found during
the previous power supply, solar panel charging system or AC charging circuit troubleshooting tests.
Step-by-step instructions
Disconnect the solar panel charger or AC charger.
Disconnect the battery pack cable from the XRC
G4
board and substitute a known good battery, if not already done.
Disconnect any auxiliary equipment that draws power from the XRC
G4
or battery pack. This is not limited to, but should
include, removing the J20 auxiliary power output connector if used.
Connect the current measurement troubleshooting cable (Part No. 2017350-xxx, see Figure 82), to a known good battery
and re-connect to XRC
G4
board.
Using DMM, connect to the troubleshooting cable and measure the average current. If equal to or greater than 80 mA at
12 Vdc, disconnect the battery pack and reconnect one auxiliary item. Continue to next step.
If the average current is less than specification, replace the main electronic board following the instructions in Section 4,
Maintenance
.
Re-connect the battery pack and measure the average current. If the average current is less than or equal to the
equipment specification, disconnect the battery pack, and reconnect the next auxiliary item. Continue to next step.
Repeat step 6 until all auxiliary items have been tested and/or the equipment causing the power drain has been located.
If the power drain has not been located, return to Figure 80:
