The test is to determine if there is an additional problem other than the pickup falling off. If it runs then the only problem you have to solve is how to reattach the pickup. It is so easy today to go online to find parts that we do not sometimes look at the easiest solution which in this case might be just making a spacer out of insulated material. It could be as simple as a piece of cardboard or as hard as sending it off for repair.
