Bally 6000 board problem....always says 65 Meter disconnect

[mrcrazy]

im sure its the board as the problem follows the board not the game. I can put a different board in the problem game & the 65 goes away so im SURE its the board. Can anyone tell me what chip or chips would be responsible for this error? I changed a few of the larger ones out figuring they were similar to PIA chips but no change. I only have 2 bally machines to fix & down to all problematic boards & would really like to get this one going.

Please let me know if you know where I should be looking on this MPU.

thanks!

I haven't done much work on the Bally 6000 at all. But here is the meter detect circuit from the prints. U14, RP6 and RP1 are about it - if? this is for your MPU board.

If U14 is bad - I would think the other switches would be problems also. Could be a bad resistor pack ( RP6 or RP1 ) I've seen bad ones, usually a crack, but rare. You can ohm out the signals from the MPU connector to and through the resistors.

PM me if you need more direction.

THANKS so much for the reply & the response. I will give it a try today! The attachment you have looks like its for a video poker board, I assume that circuit is the same?

I will let you know the progress after I go to the shop today!

Hello,

Can you post a pic of the DS2 and DS3 micro switch ?

Other wise :
DS3 => put all the micro switches to ON then perform a ram clear.

65 Mechanical Meter Disconnect
The electromechanical meters are disconnected from the machine (Market Codes 3, 4, 12, 28, and 29).

I did & tried everything suggested to no avail.... I ended up moving on to other problem boards & one of the boards that had no display & replaced the two 6522 chips & it fired up.....

got the machine working but still have this board with the same problem. I have ONE MORE bally 600 to do, I'll probably try to fix a different board when that time comes. Right now working on some Williams 550 machines...

thanks for the help & suggestion guys, much appreciated.
