The lower bumper seems to work fine when I first turn the machine on and play a game. Then after a game or 2 it will just not respond and when hit it will set off the upper bumper and do nothing itself but seems like it wants to.
On both I have changed the sleeve in the coil, skirt, new spoon, cleaned the contacts on the switch and just cause I had them next to me when I was doing this I also replaced the resister in the proper direction.
Everything ive read says the coils just would not work and time would not degrade them. They look in good shape. But I am sure they are the originals. Some 30 plus years old?
What do I need to look for here?
Thanks in advance
This picture is before I cleaned them up and replaced these things.
