Ok I've done the test "0" is flashing I push other switches and the switch number comes up on the screen, but when I press the credit button nothing shows up. I've checked for continuity thru the plug and all the way to the MPU and it checks out fine. Could it be the mpu? It's a new alltek one.
Another thing the diode on the switch, could the direction that it Is wired in affect it?
