My First Pin - Flight 2000 (Pics)
Neverending Project:
There is only one unique wire to each coil - it is the last coil in the chain. See my highly-technical, extraordinarily artistic 30-second picture attached.
I believe the coil is smoking when I power the game on. I haven't turned it on since, but I will definitely check all the drive transistors.
My hunch is that there was originally at least one bad transistor, and now there are are two shorted coils also. I have verified with a multimeter that the two smoking coils are now bad, and have disconnected them. Before I power the game back up, I want to check the drive transistors to make sure none of the other coils will be fried as well. Oh, and get the proper fuse in there...

Hi "Neverending Project",
what about your Flight 2000 ... does it work now? Hopefully it does.
I just startet a project to program that Flight for "Future Pinball", fascinated from the multiball lock-system. But as I never saw a Flight 2000 in real life I have some questions as to the rules of the game. Also I would need the original sounds of the different targets and rollovers as also the voice.
Do you think you are able to help me?

Hello martinB. Sorry I didn't get your post until now... I have not made any more progress on this pin. I have a terrible habit of starting new projects before I finish the ones I am working on. The good news is that I did finish my last project (which interrupted this one)! The bad news is that I have also started other projects in between... :-\
I plan on getting back to this restoration, and when I do I will be happy to help if you still need it.

Well, this is absolutely true. The positive side to having a bunch of unfinished projects is that you get to hop from one unfinished project to the next - you know, to prevent getting too frustrated bored with one project. So I helped my Dad fix his pinball game last night, and got the urge to work on mine again, so I did.
I replaced a couple of shorted (burned) coils that I fried sometime when I first got this game. And since I have last posted in this thread (over a year ago!) I have rebuilt the rectifier board and SDU board, including the HV and 5V circuits. So I know these areas are good.
Now when I power on the game at least one coil fires immediately (the outhole coil) and blows the 1Amp fuse under the playfield. I can't tell (yet) if more than this coil fires when I power it on. Here's what I have checked:
Coil resistance - ~13Ohms (Good)
Coil Diode - Pulled one lug and tests Good
SDU transistor - Good
SDU diode - Good
SDU resistor - Good
So here is my question. Clay lists the following tips on his site, but they seem to contradict each other:
--- Quote ---Remember there are two fuses that handle power for the coils. The 1 amp underplayfield slow blow fuse will usually only blow if a coil is energized and staying energized. Yet the power supply F4 fast blow fuse usually blows if there is a "hard short" (a dead-short across a diode, or coil that is shorted out (less than 2 ohms), or coil power is shorting directly against a metal ground).
--- End quote ---
And a little bit further down he says:
--- Quote ---The under the playfield solenoid fuse is usually located on the right hand side by the flippers. Usually it's a 1 amp slo-blo fuse. If this fuse keeps blowing, you have a solenoid problem on the playfield somewhere. This can be caused by a shorted coil, a bad coil diode, or a broken (and shorted) coil wire. A shorted and locked on driver transistor is probably NOT your problem.
--- End quote ---
So first he says that a shorted coil or diode will blow F4 and it is caused by an SDU transistor, then he says that a shorted coil or diode will cause the playfield fuse to blow.
I am trying to figure out the best way to isolate my problem, but this confuses me. Any suggestions? I may just disocnnect each of the ground wires from the coils and reconnect them one at a time until I see a problem, but that is a lot of work. Is there a better method?
Neverending Project:
Sounds like a better method than my desolder-a-thon. I'll give 'er a try.
