Hi I have a Base hit williams pinball machine I had the whole machine working 100 percent I use the coin door for my grandkids they like to put in quarters just stop working since I went to free play so I took it off free play still nothing the coil on door does not energizes all wires seem good like I said was working before I went to free play any suggestion
 
On the credit/replay unit the zero position switches need to be checked.
This switch might be a 3 blade make/break design. Or a 4 blade 2 switch design.
Usually the upper switch circuit involves the replay button from working at zero position.
The lower switch circuit involves the coin door lock out coil. The lock out coil will only energize when this switch closes at zero position. Score motor rotation may also pulse the lock out coil. So the only time that coin mechs can accept coins is when the lock out coil is pulled in.
