That is a diode across the coil terminals for a more modern DC voltage pinball game. On older AC voltage games like yours the diode should be cut out.

To help visualize here are the post schematics and relay setup from a Straight Flush Williams pin. It should be very similar.

Clip that diode off of the new coil and see if the problem goes away.

Your scoring problem is probably going to be in the switches on the drums.
Here is how the switches work.
