I have a pinbot that has a low dc voltages on the power supply output pins of jacks 3j6, and 3j5. Any idea what to troubleshoot in the board, or is the problem with the main transformer?
My measured votages off the power supply board are:
J5 connector:
pin3 -99.5vdc good
pin4 +105.4 vdc slightly high (+90 to +105.0)
pin6 +2.74 vdc LOW (+4.9 to +5.2 normal)
J6 Connector:
pin2 -14.2 vdc good
pin6 +14.26 vdc good
pins 7,8,9 +3.03 LOW (normal +4.9vdc to +5.2vdc
Any ideas?
I am told the game will not work with 5v output pins that low.
