Okay, so I got my BoP working tonight. While I was cleaning up, my friend played one game, completely successful. Then I touched the coin door, the game gave me one random credit, and then the playfield shut off and now when I turn it on nothing below the display turns on at all.

I know I've seen this problem with these WPC coin door causing all manner of havok, but I'm at a loss for the solution.

And I was so close...

Yeah, all the fuses are fine.

Thanks for the lead Prmailers, it'll give me something to work with.

The slam switch is fine and I can't see anything wrong with the wiring. I'll have to spend more time on it and really get down to brass tacks. I'm about ready to throw this machine into traffic

Okay, the handle is wrapped up to a point, and when the short occured, I didn't have the bar in its rightful place. If that caused the problem, what would be the solution or where along should I be checking?

More intel: Now that there is no power below the displays, the LED2 on the main board is no coming on. The game boots but won't go into test mode, as none of the functions on the coin door seem to be getting power.

The batteries haven't been leaking, but I am having trouble with the game keeping the settings. I didn't think the problems were part of the same issue, so I was focusing on getting the game to actually play before messing with the batteries.

I have checked them though, and replaced them. The bottom contacts on two of the battery ports are missing some of the metal.

Thank you. I'll try that tonight when I get off work.

Yeah, that's it. TP3 isn't getting any juice.

It doesn't look like I'm getting anything to the Q2 transistor. It's attached to a heat sink but generates no heat when the game is turned on.

Eh, at this point I'd walk to jameco through zombie apocalypse to pick up the part.

Okay, now we are waiting for the part order. I'll have the finals (hopefully) in a few days to a week.

Okay, I've got her booting and testing. She's saying there's a pinball missing when you try to start a game and the game resets factory settings everytime you turn in off.

Getting so close...

Oh snap! I just got a game in! Once I get that CMOS battery thing resolved, I should have her better than when I bought her.

Thank you guys for all your help. This machine has always been my worst nightmare.

Any more tips on the factory reset issue would be greatly appreciated.

Okay got it! Here's what happend, in case anyone comes across the need for it:

I was getting a "factory reset" message every time I turned on the machine. I tested the batteries individually and they were all fine.

Then I tested pins 26,26, and 28 on the chip at U8. They are the three on the upper right of the chip. They tested at no voltage.

I tested the diode at D2 and only got power going one way. Replacing this diode fixed the problem.
