“power In” plug and measure the DC voltage from the solar panel it
typically should be about 19 to 22 VDC. This reading must be taken
when the skies are clear and the sun is up directly on the panel.
NOTE: This reading does not guarantee the solar panel is outputting
the correct current to keep the battery charged, but it is a good
rst check.

light does not come ON when connected to the charger / charge
controller then it is bad, replace with USAutomatic part # 520007.
