I have a Williams Dipsy doodle and when I start the game the relays will pull in and not stay energized for the duration needed( say when the ball is in the outhole so it can be kicked out). Looked at all the switches and all seem to function. Score motor switch stacks all open and closed as they should. Machine was a re-import from Germany so it had the 50hz motor and transformer. I’ve replaced the motor with the correct one so it is running the correct rpm’s. Any ideas? Thanks in advance.
