Lift your playfield and get your multimeter out. Set it to 200V DC voltage. Take your probes, put one on the braided ground strap running through the inside cabinet of the pin. Take the other and place it on either of the coil lugs. You should be getting near 70V.

Also, set your DMM to 20 ohms resistance. Put each of your probes on the lugs, 1 probe on 1 lug each. You should be getting I believe anywhere from 2 ohms to 15 ohms. If you are getting zero, you have a broken coil wire somewhere in the coil. Sometimes you may get lucky and it is just a broken wire right at the end; other times you may have to get a new coil.

Let us know what the results of these two tests are.
