With all the electronics working, I went ahead and moved to the bottom of the playfield. There is quite a bit of rust and dirty switches on the bottom half of the playfield. The top half of the playfield looks quite a bit better. I am working from the bottom of the playfield on up.
I am just cleaning switches and not fine tuning them quite yet. I am taking apart each coil and mech and cleaning and adjusting. I replaced each coil sleeve and cleaned the plunger with a wire brush on my Dremel. I got through the sling shots and the ball kicker. I am going to wait on the flippers until the end and see if they will need rebuilt or not. Some of the parts including coils look newer.
