I have installed this board last night and kept getting GFCI Self Test Fails... then with self test off, I got GFCI fail when plugging in car. Today I have checked the wiring and connections (reseeded and re did the ties). I still have the same error. Any suggestions on how to get past my GFCI issues?

The GFCI coil is likely plugged into the AMP position and the AMP coil plugged into the GFCi position. The JuiceBox engineers used the same connector for both so it is easy to plug into the wrong connector.
This guide was perfect! It accurately described the steps needed to replace the original Juicebox v2 board.
Thank you!

The same plugs, etc., and the same board as the 32/40A to
Thank and advance
