Boston, not sure what GDS means, but remember that if a lift trips the safety gear or anything mechanically for that matter, if you short out the electrical cct, it should mean you can move the hoist motor(safely of course) but it may still mean its tripped mechanically still. If you cant move the hoist motor then it will more than likely mean that the cct is not complete with limits/modules/contacts etc. I would suggest that if it wont move you still have an open cct somewhere. The lift should at least slip thru the sheave which tells you the cct is ok. You then would still need to fix the mechanical issue.
