CSI: Crime Scene Investigation
Stern, 2008Hello pinside. I turn on my machine and it blows f10 fuse instantly. I have researched the problem here and this what I did. I unplugged all the connectors from power supply board(not the molex). The fuse still blew instantly. LTG says that this a bad bridge. I traced F10 to the bottom right bridge with a heatsink. I plan ordering a new one from macros and replacing it.
If y'all have any advice or any words of wisdom that would be great.

LTG : )
Oh yeah testing...oops. I tested all of them for some odd reason 3 of the five were bad. I wonder why more fuses where not blown? This what I plan on ordering.

Quoted from LTG:Do you need the spade lug ones like in your picture, or wire lead ones ?
It seems the correct rectifier with spades, and I'm quite sure that it is not the bottom right with heatsink but the rectifier just below F9 and F10.
Quoted from LTG:You were testing them in circuit. I'd just replace the dead shorted one.
LTG : )
You are correct. Apparently testing boards at 3:00 in morning is no good. Just retested all good but one.

Not sure I'll desoder before I order.

Yep I was wrong. I'm not sure how I got so far off following a trace.
Issue resolved...I bought another board from K's arcade. I checked for any dead shorts/bad coils before installing. The original board did have other issues....centrifuge lock gate would not stay up and the GI's. would not go out at the start of mutiball. Yeah I fucked that board up....practice on old boards do it first for the love of God!!!!!
