Mine were in parallel now that I think about it, for whatever that is worth.

@ Jeanna:

On this page are some close-up photos of my board.  You can compare to what you have.  Let me know.

One difference is that since that was taken, I cut the lead to the diode on the end without the stripe as was suggested to me.  That really helped my output.

Thanks Bill,

That will save me hours!!

I think the fuji I bought is closest to zee's, but I still think it is different. I have been to joseph pino's site and removed much of what should go, but I have a couple extra resistors and I have a black/grey thing that I believe is a diode as well as a glass diode.

The glass diode has a yellow stripe. Is that the (-) ?

So,
2 diodes,
3 resistors,
1 darlington transistor,
1silver thing someone said was a TDK cap,
1 large transformer,
1 coil,
battery holder still in place as copper braces.

I am not sure which resistors to remove. There is a black paint over the lines underneath so I cannot read where they attach. I can read one of them which goes from a switch to the silver cap.

What was that thin black plastic thing with 2 copper leads. It seemed to be in the right place on the camera to be a switch or a cap turn on somehow... Anyway, it is gone.

xee did you end up with a bulb glowing from your fuji ckt?

I think I am close. I better study the circuit some more to understand what it is supposed to be doing.

@ Jeanna:

That thing with the copper contacts is a contact switch.  You remove it.  I only have 2 resistors, that funky metal cap and the transformer and trigger coil left on my board. Everything else is gone...well I left the diode because you hook a lead to the side with the gray stripe on it.  (not sure if anode or cathode)  I just cut the other side and bent the diode up from the board a bit.
