Flipper coils not firing

[darren_ross]

Okay so I've just had cpu and driver board back from being repaired. Stuck them back in and the game poweref up fine. Start a game and two ball poppers are constantly firing and i have nothing on the flippers. Reseating everything and still the same. Fuses are all fine.

do you have a working boardset to swap out from another machine?,that would be the obvious thing to try first

Sounds like you have no 12v Opto supply. Check in switch test. You may have missed one of the connectors bottom left of the driver board or pulled one of its wires out.

Yes i can swap this over. That was my next port of call.

I kept checking that area as i had missed one previously but couldn't see anything and i checked against another machine. Will look for a wire that may of come out on connector

I think it's a pin as I'm pretty thorough after having those wedged behind last time . I'll get to the bottom of it tonight. Was a long weekend.

Nothing out here.
When the machine first boots up the ball poppers eject.
Start game and they continuous pop and nothing on flippers

Check the two 12v test points- one should be close to 12, the other one can be 13-15, are they both ok?

Where are the test points Dan?

Okay I've sorted the thing. Completely removed the board and stuck it in another machine to test it and it was fine. Put the board back in and found a connector in the wrong way round. The green white at top of board. It's had a different type of connector put on it and fits both ways!
Cheers guys
