Thank you xee2,

That is the attachment to the (+) battery terminal.

Here is another pic with the switch circled. I think I ruined the picture of the 2 fingers on this one but if you look at this you can see on the other pic what it looks like.

The switch is in a different place from Bill's. I think the architecture of the board changed a lot when they moved to the AAA battery. It looked similar on the outside, but it is a very different switch.

HEY I got lucky.
I just opened the only camera that had a different look and it is one like Bills!! yeay! That is how I can say it changed so much. It is really different.

Back to the one I have 6 of...

Here is the pic showing the switch in place. It is part of the board on this style.

Thank you xee,

@ jeanna

In order to have the flash switch in the same place on camera body, the flash switch would seem to have to go where marked. Is it possible that the switch is shorting this thing to the metal trace surrounding it?

That appears to be the positive battery holder end where it sticks through the board.  I believe my board is exactly like Jeanna's, for whatever that's worth.  Maybe I can fire it up on Sunday sometime.  I striped almost all of the non-needed parts off, at least I hope they are not needed... ha ha.

Does it have an AA battery as opposed to a AAA bat?  If so, I'll bet it is exactly like mine.  This is good as it appears we may only be dealing with 2 styles here. (AA style and AAA style)  That is good news Jeanna.

HEY I got lucky.

    Great news. I hope you have enough information now to modify it. Good luck.

On the other boards, did you try shorting out the switch?

@Bill, this one has a AA. The size of the battery makes the whole design different (as xee pointed out) in order to accomodate the switch staying in the same ergonomic place.

Yup. I think 2 basic styles. It seems I have 3 of each (yesterday's is trash). I bought a 2pack today and went to the counter and asked if I could 'have' 4 more, but I bought the 2 pack. One was like yours and 3 were like mine.

I decided to open the one that looked a bit different and it was like yours. Then I opened the 2 pack and they are both like yours!!!! yeay I really got lucky.

Anyway, I need to turn in. I will be at this again tomorrow.

Thanks everybody for all your help. (Wilby, I will need to really study your suggestion)

@xee2,

Smiley  Great news. I hope you have enough information now to modify it. Goodluck.

I will see if I can figure out where I would go to short it out. pushing the switch in toward the board while clipping the fluro tube did not get it on nor did it light the led on the torroid jt , so, I think something is open that should not be.
