So I upgraded to leds
Rebuilt flippers and change rubber
Now my
Slingshot switch’s
All 3 bumper switches
And DIG switches do not work
All 8 of those share a common wire
I have checked fuses wiring but cannot find a problem
Any help would be appreciated
Follow that green/blue wire from J207.6 (the wire is securely punched down in the connector pin?) to all affected switches. Check for broken/loose wire.
Did you do any of that work with the game powered up?
Quoted from cody_chunn:Follow that green/blue wire from J207.6 (the wire is securely punched down in the connector pin?) to all affected switches. Check for broken/loose wire.

No I did not
I thinks it’s the uln2803 chip
I traced the wire back to the connector
I have low voltage out of it compared to all the others
I removed the wire from that terminal
And put it into a different switch terminal
With it in a different spot it all works fine
I then checked voltage at the uln2803 chip for that wire
It had good voltage in compared to the others all the same on each pin
But on the output pin for the switch driver was very low
Like 2 volts
Others if I remember correct were around 5v
