Check for a poor cable connection in the cable between the XRC
Verify that all field wiring screw terminals are tight.
Correct and retest, as necessary.
Verify that there are no other devices that may drop an excessive voltage across them in the power supply circuit (to the
G4
XRC ).
Correct and retest, as necessary.
Disconnect the charging source cable at the XRC
Replace the battery with a known good battery, using the procedure in section 4.6, Replacing the XRCG4 battery pack.
Reconnect the charging source cable to the XRC
Measure the voltage at the charging source cable. Measure the voltage at battery pack. Compare voltages. If the
charging source voltage is less than (+) 0.4 Vdc higher than the battery voltage, return to Figure 80: Power
troubleshooting flowchart and continue.
Solar panel charging system test
If the system setup includes a solar panel charger connected to the XRC
G4
the XRC unit, test the solar panel. The following instructions contain the steps required to do so.
Step-by-step instructions
Check the solar panel angle and direction. In the northern hemisphere, the panel should face due south and in the
southern hemisphere, it should face due north.
Correct and retest, as necessary.
Check the solar panel for any physical damage or obstructions to sunlight. Sunlight obstruction prevents the solar panel
from receiving enough sunlight to charge the installed battery pack.
Clean, correct and retest, as necessary.
The solar panel should be positioned so that it receives the most sunlight. Do not place it in a shaded area.
Correct and retest, as necessary.
Check the solar panel wiring to be certain it is correctly connected to the associated XRC
Correct and retest, as necessary.
Measure the solar panel voltage at the connector using a DMM connecting the (+) and (-) leads to the (+) and (-) solar
panel wires. Loaded voltage should be greater than or equal to the specification listed in Table 17.
If the solar panel is not above minimum, replace the solar panel. Return to step 1.
Disconnect the solar panel from the XRC
Set the DMM range to read over 20 Vdc.
