I can't get into test mode on my new Diner. The advance button tests good with the meter. I'm not sure what connector or pins to test (jump) on the board. Any thoughts or suggestions would be greatly appreciated. Thanks

It appears that only the high score reset button sw is listed on the sw matrix table....I'm lost.

Somewhere the advance button sw connects to the MPU, but where?

Thanks, found it now. So would jumping pins 2 and 3 be the same as pushing the advance button?

I'll never die young......Not at my age!
Hey found the problem though. The wires and connector that were supposed to go to 1j14 were plugged into j-1 of the sound board. Next question....I'm not sure if j-1 on the sound board is supposed to have anything hooked to it. On my Whirlwind it is used, and goes to 1j16 on the MPU board. The diner 1j16 MPU does not appear to be used, as there are no pins at 1j16. On the Diner schematic for the audio board, it says to interface CPU.
