Diagnosing Stern Spike 2 Node Board Problems With Jaws Pinball

In this video I dive into diagnosing an error condition with a 48v node board for Stern’s Spike 2 pinball system. In this case, I have a Jaws Pro where most of the switches went out and a lot of coils stopped working. The machine says “Node 9 not found” so we’re going to take a look at what the problem is.

It must have come this way from the factory.

Note I say “infrared” but I obviously mean “ultraviolet.”

Bally Embryon Pinball – First look and initial repairs

I’m very excited I was able to pick up one of my grail games – an early 80s Bally Embryon. Here is some of my progress.

In the next video, I begin to go over what’s wrong with the game and work on it. First order of business is dealing with flippers – on these Bally games, there are some issues with EOS switches.

Next we move onto dealing with drop targets.
