Thanks Brewski!
Looks like they confused the truck by leaving carts (automotive glass distributor) on the forks which left it elevated above the 24" switch while charging etc.
Had to enter the diagnostics to get the lift and lower running again and nest the mast. Once it saw the mast prox switch and regained its reference, it started working normally again.
Still looking for a book for future reference. Email in my profile :)
