Hi guys:
still working on the re work on my fire queen. this is where I'm at.
trip coin switch in coin door and adds 1 credit, press start button everything resets, score reels all to zero, ball comes out on to runway.
back glass shows 1 player( this is a two player game) ball count shows no. 1. ball plays....goes into drain hole and comes out to runway again but goes to player two. that ball plays and we go to player one again at ball count is now at 2.( have set up on 3 ball at moment) and this continues till ball 3 and game end on player one ball 3.
hoping someone can tell me what switch/relays determine 1 player or 2 players. I've read endless topics on the forum but not having much luck.
have schematic and getting better at reading them, but a lot of it just not clicking just yet in the brain...lol
also if I put 2 credits up and play a two player game the player unit will not advance. stays on 1st ball and 1st player.
any help will be greatly appreciated.

thanks for quick input currieddogg, fire queen has no coin unit that i can find. player unit up to specs, just went and read peruman restore on soccer game and looked like my problem a little, and howardR told him to check his motor 2c switch and I said let me check mine also........ low and behold.......2C not making good contact. she is back to working now.. thanks..now on to next problem.
