ok will check as well a further bit of info. was told it was rained on while it was parked in the worst place of the warehouse. Overhead leak pouring right on to the lift so now I am concerned about what was damaged by the water. Yet I used contact cleaner and compressed air to dry it all out. Only thing it was a full two days that this was left with the battery connected. When I was made aware of it is when I removed the power and attempted to dry out the controls. We let the lift dry for 5 days and then applied the power to the lift and got the error -50.
