Pin 5 and 6 both stay solid low when i turn the game on and stays that way. I set logic probe on a leg..turn game on and instantly is low...not even a glimmer of a change.
I also switched the game to test mode with the logic probe on the pin and nothing changed. I also started a game, and same results.
I did this for 5 and 6 individually.
Then for shits and giggles i put logic probe on back side of edge connector to black wire...it beeped low...i press the pedal...it stays low...i put logic probe on tab with black wire on pot...stays low.
Then i put logic probe on back side of edge connector to red wire and it stays high....i press pedal, and stays high, i put logic probe on pot tab which red wire soldered to and stays high when i press pedal.
Shouldnt probe change from high to low or visa versa at edge connector or pot when i press pedal?
(I did do these edge connector and pot tests with the game coined up to qualify)
So i have a high (red wire) and a low (black wire) signal going to F of edge connector.
The probe detect state changes by reading voltage, kinda. Anything below 2.5 or so will be considered low by the logic probe. Anything above 2.5 will be considered hi by the logic probe. Depending on how you have that pot set it may never climb above 2.5 VDC which is why the probe stays low even when you operate the pedal.
Now, onto the heart of the matter.
GASEL should change state when the game is started or put into test mode. Since its not lets look at where GASEL comes from...
GASEL looks like it comes from pin 7 of 8E. Check it there to see what its doing when the game is in test mode.
