Is it the one shown here and labeled as #10?

If so, then it should be FC-30-1300 as shown here:

I will make a guess that this correlates to the "Open Flipper Coil" which is at E-34 in the schematic and is also labeled FC-30-1300.

I have been doing a lot of looking at the Bally parts catalog and the schematics for my Bally EMs, and one thing I have noticed is that there is inconsistent naming of various parts. This makes it difficult sometimes to figure things out. If they used the same nomenclature in the parts catalog and in the schematic it would make things easier.

The only thing I know to do is call Pinball Resource and given them the part number and see if they have it.

I needed a spring for a knocker solenoid also and PBR didn't have it. I have a Bally Bon Voyage and a Bally Monte Carlo which have the same knocker solenoid, but when I got the Monte Carlo the spring was missing. But I figure that maybe the spring can be found somewhere, or a close enough match. Somewhere like here which I picked at random. http://www.leespring.com I know they also have cases of different size springs at Ace Hardware and such. One of these days I am going to pull the spring from the working knocker and take it to see if I can find a replacement. Been too busy lately to deal with it. I should be a matter of matching the diameter, length, etc.
