ON power up the blue thumper bumper locks on. I have taken the coil and the controlling relay out of the circuit and they both test to the stated ohms on the wiring diagram. I have cleaned and inspected the associated switches. Any help? Thank you in advance. Richard

It locks on instantly when you turn the machine on, not when you start a game?

I overlooked this post from 4 months ago. To answer your question, yes, locks on at power up. But since then went through machine stem to stern, cleaned everything, suspect it was dirty Jones plug messing up a connection, or a dirty switch. 50 years later all it needed was a good cleaning, all relays worked. Thanks for taking the time to respond!
