No, that's a flipper coil.

Yes.

ebay.com link: i I'd see if any cheaper on Ebay.

LTG : )

I mean, you could? Just don't hook up the third lug.

Yes you could. But if the right thing is available, and a person wants to know IF it will work. I'm not going to say yes and chance hooking it up wrong and causing problems.

LTG : )

On another note, you might want to add a fuse for that coil if you're making it any stronger. 23-800 is at the lower limit of what those boards can handle iirc. Small chance you'll end up popping the transistor, can't hurt to be safe

Seems like you have some sort of mechanical problem still that should be fixed rather than making the coil stronger...

The coil numbers are the gauge of the wire followed by the number of windings. So in this case it is a coil made of 23 gauge wire and 800 coils around the center. The lower the resistance of the coil, the more power it would have. So having thicker wire like 22 gauge would help and/or less turns would help. I would start with a 23-700 since those are pretty readily available. The next standard size that you might find is a 22-600. I would seriously just fix the real problem before trying that one though!
