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

Disconnect any auxiliary equipment that draws power from the XRC

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

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: Power troubleshooting flow chart.
