Greetings,
Just picked up a BG two weeks ago. Decent condition outside of some surface rust and dead bulbs. I've performed the usual maintenance and she's humming along. The only strange thing is that the the 89 flashers up top/center are constantly on at 31.5V. I tossed in some 1251 bulbs and it's like staring into God's flashlight. Anyone have any idea what root cause would cause this type of failure mode? Bad resistor on the lower board? Shot diode on the Aux power board?
Thanks!

On page 1 someone mentioned 83" of clearance for this game. Can someone please measure their's and let me know for sure what the full height is?
I have a chance to get one of these to work on.

Sounds like you have a closed short to the bulbs. Run the diagnostics and see if you get an error message. The manual for this machine if you dont have it is here http://mirror2.ipdb.org/files/250/Williams_1987_Big_Guns_Manual.pdf. the Lamp matrix is on page 52 an tells you which wires go to those flashers, I would start there and trace the wires.

lamp test diagnostics can be found on page 27

Also I see you are getting an error popper front left. if I am not mistaken that popper is tied to the flasher, which means the short is probably there. If you look at the second page you will notice on the solenoid table the ball popper flasher. gives a list of wire colors, transistors, solenoid etc. Start your trouble shooting there

Good Luck

Can any body snap me a pic of left cannon switch wiring please.... I too am having problem with cannon lock

Also any idea where this wire is supposed to go

My big guns' right canon always misfires. It releases the ball early, triggering a false 2 ball multiball. sometimes it happens from a launch of the ball out of the shooter lane, sometimes from something else on the playfield. I originally thought it was due to a vibration causing a switch closure or similar, but cant see what triggers the canon release firing. Always the right canon misfiring, never the left. No switch errors.
Any assistance is appreciated. thanks

Reflow the solder on the switch. If that doesn't do it, replace the diode. If that doesn't, replace the switch. If that doesn't, you're stuck where I am. New switch fixed one of mine, but the other is still doing it...

What do people do for moulding on the back glass? As big guns is taller than any other back glass, the normal holding lengths don't fit? It would annoy me having gaps of the edge showing

buy three long ones (top trim) and cut the two side ones down to fit. (pretty sure that's what i did)

Can anyone tell me what the proper flipper coils are for the upper flippers ?

FL-11753/50v

Thanks Dozer. Im working on a friends Big Guns and the upper flippers seem too powerfull. Lots of crazy flying balls. It has FL23-600s in it. Anyone know if these are proper replacements ?

Sorry, not proper replacements , but acceptable replacements .

Just finished giving ours a bit of a clean up, this gets a lot of play in the arcade.

Your answers are in this brief thread. https://pinside.com/pinball/forum/topic/replacing-sorcerer-flipper-coils-serial-vs-parallel

In a nutshell, your coils are stronger then they should be. Go with the 11753's up there.

Thanks Dozer. Interesting. So, (im not in front of the pin right now) switching back to original coils, do i need to add a resistor ? Why would someone switch to the FL-23-600s ? Are the originals lacking in power ?

All I know is the originals are just right up top. When I had a big guns, I had questionable flipper coils in there and bought some new 11753's . With them and the rest of the flipper rebuild, it played great. Not sure why they put fl-23-600 series coils in there. As far as converting back goes, I do not know exactly what it takes. Sounds like a good question for vid in the flipper rebuild thread. All I know is Vid ALWAYS says to replace any series coil with a parallel coil. I would also like to know exactly what you do there for wiring, ect. I will be watching for that.

Thanks dozer. I'm going to post this question on Vid's flipper rebuild thread.

Looking forward to joining this club next week!

I have heard this machine called "The Nickleback of pinball" because people seem to hate it, but nobody can tell you why. LOL

I like it, found a very nice example, and will be bringing it home next week. Will post pics when I get it!

Mark Ritchie and Python made some great games together, enjoy BG! I too would like to have this in my collection. I wish Mark still designed games.

Well, this didn't happen for me The game would not clear the ceiling in the basement. The seller was fantastic, and I offered to keep our deal, but he was able to seel it to somone else at the show. Bummer too, as it was VERY nice.

Maybe I will have to figure out a way to make a hole in the ceiling. I love me some Big Guns!

Does anyone else's big guns do a ball search if you hold the ball on the left flipper long enough? Doesn't do it on the right flipper, and both flippers register in switch test

Hi guys... I am probably the newest member of the Big Guns club as I've only just taken ownership of mine.. great pin.. Mine does have a couple of issues and I would really appreciate anyone's help you might of had similar issues with their Big Guns... Both the kings chamber and left outer lane kicker on mine do not fire during the game or during solenoid test (I think there are a couple of other coils that also don't fire during the coil test.. there are all around the same number 16-19 I believe).

The outer left lane kicker fires when I ground the coil at the lugs and when I ground transistor q70.. I can only get the kings chamber coil to fire when I ground the coil at the lugs... Would love to chat more with other Big Gun owners and any insight into my issue would be greatly appreciated.

1) My game is up for sale, but right before listing it, the game reset after getting the free extra ball match. I started playing the extra ball and the game reset the score to 0 during game play. There was no difference or pause, and I didn't even now it had happened until glancing at my score.
2) There is a horizontal line in Player 3 & 4. See my post in SS Tech Support Forum for details. Are you familiar with the fix for this?
https://pinside.com/pinball/forum/topic/williams-led-display-issue#post-3845279
3) The last issue I doubt I will try to fix which is a slightly raised playfield mylar separation under the right ramp. It's the size of a nickel and it's the only wear on the playfield.
4) Were can I buy the playfield insert decals without having to spend $45? I hate adding another $50 to what I have in the game when I'm selling it.

I would appreciate any help!

Looks good Milltown. Like the look of your game room.

I know this is late but did you ever get around issue #2?

trueno92 this is actually the proper behavior for the game. Whatever multiplier level is set at for lighting extra ball will flash all the time.

Chitownpinball I'm not sure but i think you did. That project has been done for about a year so i'm all good.

Picked one up a month or so back.. love the big guns...

Thanks so much for the reply.

Another quick question for the BIG crew. What's supposed to happen when the drop targets fall? I'm to receive this game but the trader mentioned this issue and id like to know where I should start looking... apparently, its not doing or actovating the bonus multiplier?

For some reason my 5x multiplier light is on all the time and flashing?
Not in attract mode but as soon as you hit start 5x starts flashing ?
Maybe the diode on the light board ?
Any ideas would be fantastic.
Thank you ahead of time...

20170928_012511 (resized).jpg

This is really great!!

That's the 'light special' (or eb?) level

Have not torn into her yet ?
Perhaps the diode on the light board?

Not sure.. I just acquired guns a little over a month ago..
But as soon as you start a game 5x is flashing ..

I'm curious?? What is ?

I've never had a issue since I've purchased big guns but noticed this tonight ..
While in attract all the lights function correctly but as soon as the start button is hit 5x is flashing threw out the game..

That wasn't a question. If you get the bonus x that high it'll light extra ball. Which number flashes is adjustable in the settings
