Bally S5500 code ch-p

[jmillican]

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
