I believe those 1985 1200 Wings had an issue with the charging system which required a costly repair to get at the problem. With those few miles I doubt it has been repaired. Not sure if Honda had a recall on the issue. You could contact member chickenman_26 as he has worked on a lot of Wings. Good luck and let us know how you come out. Actually looks nice from the pic.
The engine needs to be removed to change the stator.
The electrical system needs regular cleaning & tightening:preventive maintenance.
The owners didn't know that all the multitude of connections from the 'harness to frame' ground straps need to be metal to metal rather than the frame ground wires connecting to painted connections on the frame.
I also see that a large number of owners would overload the bike's system with electrical accessories plus not clean the connections,especially the reg/rect. harness.
I had a customer back in the 90's(Dr. Jacobs)who had an 85' GL1200 Interstate and I cleaned all the connections as noted plus made sure he always had full regular maintenance which included removing covers and making sure all connections stayed clean and tight.
He never had a stator or Reg/rect. burn out in the 10 years I serviced his bike and he had a few electrical accessories too.
That bike has been garaged(just like my former customer's 85' GL1200I in Ma.)which is great:less corrosion.
