Quoted from dracelv64:I have an EATPM where the top left VUK is not firing. In coil test if I put a meter across it, the coil fires. If no meter across, it does not fire. What is this telling me? I am a little stumped.
Sounds like a bad connection. With a load it isn’t working. With no load it tests OK.
Run a jumper to good power on another coil and see if it works when tested. The ground is the switch side of the circuit on most pinball circuits. If it doesn’t work then check ground side at connector on PPB.
