JeepMonkey:
Congrats on getting your first pinball machine. Unless this machine is a favorite I would use it as a learning tool and to get the "first machine itch" out of your system.
Did you make sure that there were no fuse holders that were missing fuses all together?

If that happens and you keep the game on all that long it will do a lot more damage someplace.

I would like to start this post by saying, for the record, that I did check the fuses, and I checked that they were properly rated. But I suppose I didn't check them close enough. What I thought was a 1-Amp slow-blow under the playfield was in fact a 10-Amp slow-blow fuse. I didn't noticed until I pulled out the fuse a second time (after two dead coils) and looked at in in bright daylight. The first time I looked at the fuse was in my garage, and most likely late at night and not so well lit. The "0" was very hard to read, and practically invisible in medium-low light.
So I just wanted to say thanks again for the advice... it is definitely very important. Now on to practice some solder skills to fix those blown transistors...

Then what might be causing smoke to be coming from the coils? It went something like this:
Got machine and turned it on. General shape explained in posts above. Reconnected lead to kick-out coil. Fired up machine and smoke coming from last coil in line (only one wire to both lugs). Disconnected this lead, fired it up. Next coil in line starts smoking. Power down machine, double check fuse, smack forehead. Bang forehead against wall a couple of times, then post here.
I haven't replaced to coil or turned on machine since. But besides fixing the blown transistors and trace on the solenoid driver, what could be causing the coils to go?

Just note that this is a very bad way to check fuse ratings because you are assuming that previous owners were responsible enough to use the correct fuses. Always go by the original manual and repair manuals.

I was checking them against the manual. I checked the playfield fuse and thought there was a 1-Amp slow-blow fuse installed, which is what the manual calls for. It was in reality a 10-Amp slow-blow fuse, but I couldn't see the "0" until the second time I checked it, in clear daylight.
