Had a few minutes again today. Start relay continues to lock on immediately when you trip the power switch on the side of the head. I turned the machine off and put about 10 credits on the replay window. Turned the machine on. Start relay locked on as usual. Hit the red button to try to play off a credit. All the credits clicked off like you were hitting the credit clear on the bottom of the machine. Bottom credit clear seems to not be stuck on. Still trying to figure out why the start relay immediately locks on when the machine is turned on.
Shutter is not closing and balls not lifting. But, if you tug or push on the playfield by grasping one of the playfield holes at the bottom the shutter will close when you push the red button.
I rechecked most of the steppers and I think I have them free, fairly clean and stepping up or down, resetting when activated by hand.
I think this game is only a few bugs to sort out away from playing. I have had the lines moving , balls lighting and scoring and the game paying out at various points over the process of working on it.
If I can correct the start relay problem , get the shutter and ball lift to operate properly, it will play....
