First check the bridge rectifier (BR2) I think it's an orange wire - looking for about 28 VDC.
If that's good then check a coil under the playfield - again looking for 28 VDC.
If that's good then check that the coil will fire. Use a jumper wire and ground the other wire on the coil (just touch it quickly to ground)
If the coil fires then the problem is on the driver board.
