Normally, I can take my time figuring out an issue, but I'm currently at a show trying to troubleshoot a Hulk.
I have a Pascal CPU board in the game (just the CPU, not the all-in-one).
Every time the game turns on or goes into test mode, I see a slam message, even though the slam switches on the coin door and ball tilt are closed.
If I jumper the slam and ground pins on the CPU to bypass the slam switch, then the entire first column of switches in the switch matrix shows up as being closed (coin chutes, tilt, etc) and a message appears that the test switch is disabled.
If I disconnect the slam switch wire from the connector and then jumper the slam and ground pins on the MPU, the game seems to operate normally, and the slam message does not appear. However, I would prefer not to leave it like this since it doesn't really solve the actual issue.
All the cabinet and playfield switch diodes test good. The coin door wiring appears to be intact, and I can't seem to find any shorts between the slam switch and anything else.
Any ideas?
