Yes, if there is continuity through a fuse it is good.

Does the game boot fine and try to start a game? If you kick the ball out by hand can you play everything else in the game? Did the game use to work for you and stopped or did you inherit this issue with the game?

I just want to make sure the problem is really localized to just this coil.

Also, using the service switches in the coin door put it in coil test mode. If all of the other coils fire then more needs to be traced. Starting with the wires in the plugs coming loose as the easiest issue to coil or the driving transistor.

OK, well this is not good. If it was a working game that developed an issue we could narrow it down. But getting a non-working project is a different animal and a bigger project than just a simple check this or that. And you have a good change of making things worse. The fact that you found and underrate fuse means a previous owner did not care to do something right.

The white button you pulled out might be an Interlock switch. This shuts down certain high power lines when the coin door is open. The switch looks like a coin switch. Many are found cut or disconnected. I don't know why.

First, I hope you checked the CPU for any previous battery leakage and replace. The set the game to free play. While debugging a game you don't want to run out of credits the think the game id not coining up.

I'm not big on the Gottlieb System 3 games so I would start here http://www.pinrepair.com/sys3/ . But from the start before even turning the game on again I would go through and check every fuse. Continuity and Value. EVERY fuse. Bottom of cabinet, under playfield, on the boards . . . Make sure the holders grip the fuses nice and tight.

There might be a good guide to working your way through the system checking voltages at test points. First, get a manual. I don't have one for this game so I can't look up specifics for you.
