Step 21: AC/Wall Mode Testing
AC wall mode is tested by plugging an extension cord into the wall and then connecting the unit through the RV outlet plug. The AC power light on the DPDT switch should come on. Switch the unit into AC mode. Switch the charge controller cutoff switch to on.
If the charge controller switch is set to on, you will see the voltage of the battery on the screen.
If the voltage of the battery is low, the orange light should be illuminated which will indicate that high current charging of the battery is occurring. You should see the battery voltage rise. At a voltage that is determined by the circuit in the charge controller, the wall brick should switch to trickle charge mode, the orange LED light should turn off, and the green LED light should turn on. At this point the battery is fully charged.
If you leave the unit plugged in, the wall brick charger should continue to trickle charge the battery.
