Measure the solar panel voltage at the connector using a MM
Connect the (+) and (-) leads to the (+) and (-) solar panel wires. Loaded voltage should be greater than or equal to
the specification listed in Table 18:
- If the solar panel is not above minimum.
- Replace the solar panel.
- Retest.
Disconnect the solar panel from the circuit board.
Set the MM range to read over 20 Vdc.
Determine if the Open Circuit voltage is greater than or equal to the specification listed in Table 18:,
- Clip the positive lead of the MM to positive wire.
- Clip the negative lead of the MM to negative wire.
- If solar panel is not above the minimum voltage, continue to the next step.
Attach the selected resistor from Table 18: between the two solar panel wires.
Clip the positive lead of the MM to the one side of the test resistor.
