Symptoms: Pinball machine wouldn’t reset.
A machine not resetting is the most common problem with an electromechanical pinball machine. In a way, it’s like a self-test, because a lot of things have to be working for the machine to reset. The reset sequence is like a series of dominoes, one item affects the next item and so on. If one item fails to reset, then the sequence is either halted, or more likely, gets stuck in a continuous reset cycle.
This Fast Draw had been not working for nearly 12 years. And typically with an EM machine that hasn’t been used for years, it usually needs some contact cleaning, contact adjustment, and the steppers rebuilt. This particular machine also had a broken wire associated with the reset relay.
