5.3.4 Solar panel charging system test

If the system setup includes a solar panel charger connected to the 6270 Optional
Equipment Unit (OEU) and is not supplying the required voltage and current to the
G4 EX unit, the user may need to test the solar panel.
The following instructions contain the steps required to test the solar panel.

through an AC charger, move to step 5; otherwise, continue to step 4.
Use a DMM that connects the (+) and (-) leads to the (+) and (-) solar panel
wires. Loaded voltage should be greater than or equal to the specifications
listed in Table 5–2. If the voltage is within range, the battery was bad.
If the loaded voltage is not above the minimum, perform the Solar Panel
Troubleshooting Test found within this chapter.
