I am beginning to lose faith in Williams as a manufacturer. I mounted mine today and it did great but I *really* had to cram it in there. Mine's a Firepower and it had the "orange and blue" colored 34 VDC wires, but also my blue 14 VAC lines were *slightly* different colored blues from each other. In fact one of my blue 14 VAC lines is the same share of blue as the blue 34 VDC line. Kinda scared the hell out of me.

Anyway -

I really had to cram it in there and had to put the blue and red wires *behind* the board essentially between the rectifiers. Is this okay? Should I figure something else out?

Also I noticed the LED's are just a little brighter after replacing this - is this a result of the new bridges? Because if it is, wow.

Oh I tried flipping the board 180 degrees, believe me. *This* was the long way to do it. I suppose I could have put them on the right inside wall of the backbox.

I used your guide and moved the fuses over to the left as far as I could without interfering with the harness. I mean if the red and blue wires are fine between the bridges I'm good with it.

It is a wonderful board, I literally have no idea what it does except make my game safer and a little more bulletproof. I have another one to install in a Pinbot soon. Thank you for your awesome contributions to our hobby.

Bump... This is still of benefit to Williams SS owners and shouldn't dry up.

YUP! Love this board and I used it in baywatch too.

I got one going in Flash soon.

It'll free up space to try something Ken Layton suggested - splitting the 20A GI fuse circuit into a 4X5A block, for simpler lighting diagnostics.

Thanks - I'll study it.

OK... I finally got around to installing the bridge board in my Flash. I guess it's my "Ken Layton Memorial" install, as he was the one who suggested I use the board instead of just replacing the filter capacitor. Unfortunately, he's not around to share in the joy of completing the task.

Anyway, it looks right to me, but I haven't quite screwed up my courage to turn the machine on. Any comments?

go on page 2 and there aa handful of pics and it looks like you have it wired right

start here and work down.

Thanks - that was my method. How's yours doing?

Oh man, I’ve sold all the games but I had them in
Baywatch
Black Knight
F14

Love these boards!
F14 went to my friend though so I can still play it

Our local assn. had a repair party to which a guy brought an F14. "What's the problem?" we asked. He plugged it in and the siren came on and stayed on! Wow!

If I finish a project in the evening, I don't test it 'til the next morning - that way, if it doesn't work I don't lose sleep trying to figure out what's wrong. So... I powered up the Flash this morning and it looks and plays fine.

The board is well made and installs neatly; thanks Peter Koch!

Thanks, Peter. I bought the stuff to split the lighting fuses, but I'm going to wait a bit. I'm not "professional grade" at pinball repair and hold myself to one change at a time. If something goes wrong, I don't have so many places to look for the reason.

I appreciate your attention, and your nice bridge board!

p.s. Did you solder one wire across the bottom tabs of the 4 fuse holders in your Firepower photo?

OK, thanks.

I just installed this in my Space Shuttle yesterday and noticed that I'm not getting 34VDC for the solenoids; I'm getting ~30VDC on the orange wires All the other voltages are Ok. The machine works perfectly, but is this a cause for concern? Is that normal? I know Cheddar installed one of these in a Space Shuttle, maybe you could post your voltages? I will go through and post all of mine later tonight.

My space shuttle is long gone. I'd expect 30vDC is acceptable. Are you noticing a loss of coil strength?

Yes, that's fine. Schematic is hard to read on my scan but it looks like it says 'unloaded' which means the voltage will vary a little bit. IIRC the solenoids all expect 28vdc so 30 is ok (except the flippers, which have the separate 50vdc supply)

My coils seems totally fine; they seem strong. Thanks everyone. Just wanted to check since it seemed low.

I’m not sure how it’s an average voltage; I would expect to read a RMS voltage when dealing with AC since the meter is RMS, but I’ve never heard of an average voltage with DC. I’m curious as to why…

Anyhow thanks for all the info!

Still love these.

Space shuttle I did today.
