credit board issues

this is a bit of a weired one. Thought it was a duff credit board but have put a Brand new one.

issue is the system keep auto crediting great i hear some say not great when your system keeps making credit noises when playing any game.

when i put the credit board wiring on the board it will be fine for a min then starts dumping credits in to the machine.

any ideas

COIN1/2 shorted to ground somewhere perhaps..? Since the problem does not seem to be related to the credit board, check wiring and the harness..

the odd thing is nothing has changed on the board will do some loom chasing see where it goes. it just started one day after swapping a new cart in to cab.

what i do is retrace what i did,if it was working fine before changing the game,change it back see what happens?if no go then possibly coin 1 wire could be shorting to ground,if it a jamma harness,it could be on the adapter.
