Hot Line Woes,
So I picked up my first single player Williams EM of this era and it has some problems that have me scratching my head. I know the schematic is on IMDB I have looked at it for probably three hours I really need to get it printed off I can’t read these on the computer but anyway here is the problem.
1. Press Start
2. Score Motor Runs
3. Relay Bank Resets
4. Play Field Matrix Says “H” like it should for about two seconds then more relays trip on the bank
5. Relay Bank Resets
6. It repeats 4 and 5 about ten times
7. Play Field Matrix Advances to “O”
8. Scores 300 points
9. And about 50% of the time it goes to ball 2.
10. Sometime pressing start will, reset the player unit, sometimes it doesn’t
11. Sometimes the games start correctly but 90% of the time it does the above mentioned.
I have been through all the switches, everything appears to be in good shape nothing stuck nothing shorted.
