Hi Pinside folks

Gottlieb Jet Spin EM

I turn the power on, the score motor runs and the coin unit energizes repeatedly.

The AX relay is energized, I manually stop it, game is lit up but will not start.

Where do I start?

Thanks, Ron

I went through the start up sequence, the O relay (game over) had one contact I adjusted.
Now the game starts and resets as it should, however...

The ball does not kick out, I manually put the ball in play, I can play player 1 OK.
After drain, the ball does not kick out or advance to player 2.
Player 1 and 4 show on backglass.

After much frustration, I took it 80 miles to a reputable EM pinball guy.

He found loose switch stacks, steppers that needed attention, relays adjusted, over 4 hours of work.

I did learn a few things!

Now it works fine!
