Gottlieb bronco EM

Postby nuttycivicsi » Tue Oct 16, 2018 7:23 pm

I have a bronco pinball
It’s in super great shape works almost perfect
Except I can not get it to add players by pushing the start button it just keeps resetting first player
I have checked everything I can think of

First, ensure that no points are scored on the 1st player at game start before attempting to add more players.
This could occur if some playfield contacts are gapped too close for instance, where a slight vibration could add points...

Then, check the following relay contacts in the cabinet for proper make/break and gapping (with the machine unplugged).
Make sure their contact stacks are tight before attempting any adjustments:
- 1st Ball relay
- Reset Control (AX) interlock relay
- confirm the Coin Unit can ratchet to position 4, and only at that position the switch at the back opens.

Good luck!
