Title: bench testing bally reels for noise. Post by: rjpohl on June 10, 2011, 12:21:51 PM anyone have a procedure for bench testing the s6000 reels? I have several to test before selling and thought bench testing would be a faster and better way to evaluate.

The reel drivers are on MPU boards. I really don't know how you can just apply power to the reel molex power pins without an MPU. ADD>>>Found it but it's not easy....might be easier to physically to swap entire reels in a working machine>>> If you take a 4 bit shift register, clock one bit around in it, connect the 3rd bit to the input,and attatch 3 bits with a 1-3 ampere darlington transistor to the 3 coils, and the common to something like 5 or 12 volt supply, shift the register with something like 5 hz(or use a pushbutton), you have a nice tester. Swap two coil wires to reverse direction. Oh and put 1 amp diodes across the coils to keep your transistors from breaking down. Title: Re: bench testing bally reels for noise. Post by: a69mopar on June 11, 2011, 12:29:34 AM put them in a running machine, turn on the machine, if they don't initialize, then hold the change/service button , press the reset button (with door open of course), continue to hole for a few seconds until the reels begin to initialize. you can then use the pseudo coin to test them.
Thanks, Wayne Title: Re: bench testing bally reels for noise. Post by: rjpohl on June 11, 2011, 07:25:33 PM Thanks Wayne, that sure seems easy enough.
