After trying to make sense of the lockout box I thought my problem was it but turns out the BDI controller was wired up incorrectly. It provides a ground for the lift circuit, and contactor. I was losing lift up intermittently, and tilt down was lowering forks also.... forklift was running around operating just fine with it wired incorrectly , that will remain a mystery.
Maybe this will help someone in the future.
