When I turn the Lethal Weapon 3 machine on it goes right to the audit and adjustment screen and continuously cycles through this screen. When the test the switch I have continuity when the switch is out, but when I depress the switch, there is no continuity, so I believe the switch to be functioning. Anyone have any suggestions

Sounds opposite what it should be. Should be open when out and
continuity when pressed. If I remember correctly, it should be the
bottom 2 lugs of the switch. Yours sounds like its on the top two.

You have your coin door test switch connection and grounds swapped on your MPU board. They are located on the bottom left corner of the board. Both are 4 pin with no key, and can get swapped accidentally.

Paul thanks for your reply and you are correct. I retested this morning it is the reverse of what I stated. Another reply suggested that I had my CPU cables at CN13&14 reversed. That corrected that issue. Back to my original problem with is with the L/R Relay not working. Previously changed my PPB board, but that did not correct the L/R Problem

Jim:
Thanks so much that was my issue with the audit & adjustment problem. I do not remember working or taking cables off the CPU board. I had switched my PPB board out from another machine since I am having a L/R relay issue, so now I can go back to my problem from a few months ago and see if I can figure that out.
