if u could get martyj or beaky to study the schematics online, u might have a chance as both are very knowledgable.
My Star Wars Trilogy is on a storage rack here otherwise I would pull it out n get beaky to help you.
I am sure it will be simple if u study the schematics. Have u also asked on Pinside incase someone on there has heard of the issue with the same magnet. ?
