My brother-in-law has (2) S2000 slots which see very little use. Recently, we powered up the machines & got the "Call Attendant", low battery message on both machines. I pulled the boards & checked battery voltages, one was completely dead & the other showed .6 volts.
I replaced the coin batteries using the removable type holders. While I had the boards out, I removed the green batteries on both boards. One of the batteries was just beginning to show signs of corrosion but no damage to board. Proceeded to re-install the board on the 1st machine and, after clearing of number of error messages, the machine came up ready to play. Inserted a bill & got 20 credits. Pressed the credits button, then spin, & all seemed well. On the next play the machine tilted out displaying "General Reel Tilt". Reset the machine, tried again & had the same result. Can't get the machine to stop tilting out. Tried disconnecting & re-connecting the reel bundle harness a number of times with no change. Tried re-seating the main board too, no change. So, getting frustrated, I decided to try the other machine, hoping for a better result. SAME situation on that machine! Am I not doing something correctly? What do I try next?
