Hi guys. Over the years I have read a lot about yigs going bad specifically their coils seem to go bad. Is there anything that can be done pre-emptively to secure their longevity? And what exactly happens? Do the coils open due to excessive current (like a fuse?) I know there is an issue where the sphere sometimes moves and gets located incorrectly IIRC. I don’t know what causes that, perhaps excessive force? But I am interested in the coil issue. I have no yig issues at the moment, which seems like a good time to try to prevent it?
