Quoted from Pacer:This is often caused by the wire for the goalie "hit" switch not being properly seated within its guide as it goes down the back of the goalie. This allows the wire to become separated from the post that it rides down. The wire then trips the opto that indicates the end of the side-to-side goalie movement stroke and causes the motor to reverse prematurely. There are little raised dots that define the wire path in the moving post. Make sure your wire is seated in that vertical track.
Can I see if it is aligned correctly without disassembling anything? If so it looks to be aligned correctly. Waiting on parts to arrive before I start the complete shop out...
