They are taking about putting a E2000 MPU into a machine that has the E1000 MPU now.. I did not think that's possible? All tho I have seen early E2000 machines still using the earlier E1000 MPU..

sorry - didn't read the entire tread - but info I provided may be of help for those with a lot of e1000 mpu boards.

So I moved the switch plate over a little and I tried to run the tests. All I heard was a clicking noise every time I pressed the test button. I could not figure it out. I decided to unplug and try again in the morning. I tried again and same issues. I went to work and thought about what I had changed yesterday. today I came home moved the switch over a small amount , then I  hit the test button and it worked. then I closed the door the light went off . put nickel in and pulled handle and the error 50 went away. Finally its all working perfect. For a 30+ year baby it a nice to see working like it should. Thanks to all for assistance and push me the right direction to figure these little issues out. I look forward to my next project that I can start on. I attached the finished product.

Your MPU board is the older series 1000 board, they later made a series 2000 MPU board. If you ever need to you can replace your MPU with one of the series 2000 boards, they are compatible and often easier to find.

This is not true.. I'm not an expert but I know that you can't just swap a 1000 MPU with a 2000 MPU. I don't know the whole reasons why, but there are a few slight differences. One has to do with the hopper and the relay boards found in the E1000 next to the beau plug.
I had one machine that was an E1000 series and wouldn't payout on a higher jackpot. It had been switched to a later model E2000 MPU.. Once a E1000 MPU was installed it paid out on the larger jackpot.

ok, thanks for the correction, I thought from reading thru the Bally manual that they are interchangeable.


Nice looking & colorful machine.

Glad to see it working..  It could have been that the hinge switch was stuck from sitting or just sticky from sitting. Sometimes the best thing to do is not to over think the problems. Nice job.

If your happy with our help, please donate a small amount to NLG to help keep this sight operating.

Thank, Gary

Today i tried changing the small light bulbs on the front glass. i forgot to turn power off. After i checked the fuses i saw one was blown . i replaced it with one from my other machine, I tried to play and i am getting error 71. i took the wheels off and then tried to pull handle after i put back on and it moved like half a turn. i have a 5 coin machine and coin up 1 3 5 started to flash. i tried to reset and nothing. i was able to use test 8 and play a few times but it sometime just starts flashing. i did disconnect all the wheel reader harness. i am not sure if it oxidized or not. i am going to have a friend clean out the wheel this weekend.
does 7.1 indicate wheel 1 issues or door opened?

Here is the error code list

You can fool the machine into thinking door is closed by simply moving the bottom wire of your hinge switch to the unused side of the switch.   That way you can watch it all operate with door open.
