I got a Bally S5500 slot machine and replaced the battery due to code 81, then I got a code 83-f. I moved the jumper (j10) to clear the ram and held the pseudo coin and test buttons for 5 seconds when turning machine on. Now the display reads ch-p and then 83-f. Any idea what is wrong?
thanks,
Jeff

ok I got rid of the error code but now the machine powers on and the lights turn on but the reels dont reset and it wont take any coins

Do a complete clear set jumper and hold in test and pseudo at the same time till you get a CH C then CL C then take jumper off and start game. you just did a partial clear

You are not holding the buttons in untill you get a CH C then a CL C then release the buttons. If you cant resolve email me
