Got another crazy little problem with my EM Grand Prix.
This one is not a big deal but it still bugs me.
The very top outhole is supposed to score 5000 points and advance the bonus 2 steps.
This works perfectly as long as the advance left bonus light is lit up top by the hole.
But if advance right bonus is lit up top and the ball goes in the outhole it will always score 5500 points.
We have eliminated the score cam motor in the bottom of the cabinet and the point score contacts in the back of the head.
In the photo below you can see that under the playfield there are two relays that say left advance relay and right advance relay.
The left one works perfectly and only scores 5,000 points when activated.
The right one causes the 500 point relay that is also mounted on the underside of the playfield to energize and makes the game score 5,500 points instead of 5000.
Kind of at loss as to what is causing this odd problem.
