long time listener first time caller.....

My super sweet Big Guns table has been a warrior. A champion if you will. Until just before thanksgiving! Turned her on, and got ball waiting. ball waiting. ball waiting. uggggghhhhhhh. so i pulled the glass and drained the balls one by one down the middle. they loaded in to the trough and still; BALL WAITING! Went in to test mode/ switch edges and tested the switches. boom. Left trough switch not working. went down and scooped 2 from the game exchange for like $4 each. Time to solder! took my parts home, turned off and unplugged the machine, took a picture, de-soldered the old switch, soldered in the new switch, compared pic to verify establishment and connection accuracy.... had a beer...... plugged in and turned on machine! and.... BALL WAITING! All the other trough switches work! I'm bummed. any ideas?

Thanks for the replies!

So, I did test the switch after install in test mode switch edges- no go. I’ll trace again even harder all the wires from switch back the top but everything appears to be solid. All the other switches in the row work...
unlucky #13 I guess?
Really would love to get this going again, my kids are begging to play.

Attached a couple pics for reference and can provide more if that’s helpful or needed! The switch in question is the white one in the pic and #13 in the diagram.

Thanks again!!!

To be honest I did not compare! I was under the impression that an exact replacement would need to be re installed mirroring the previous installation.

I’ll check the layout in an hour or so!

Ok just verified that the new switch is soldered to the same locations as the old switch. The diode is soldered to the no port and the solid yellow wires are soldered to the com port on the old switch and the new switch respectively...

Still not working in test mode and still ball waiting displayed..

Wondering what to do next. Trying to not get discouraged as I’m new to pinball repair but yea.. Thanks for everyone’s help thus far and I truly look forward to more replies.

Maybe together we can learn me some repairing skills

Man I am such a noob, could ya more explain the jumper scenario, please? I took a wire and bypassed the diode, switch still doesn’t appear I’m switch test... I took a wire and put the switch terminals together and it doesn’t appear in switch test. I ran a new wire from the previous switch and that didn’t work either. What baffles me is the switch before and after #13 work great. Wondering if it’s the diode but when I bypas it, that doesn’t help either. Ugh. Going to de solder this one and try that other one I got at the same time..... could it be a ground issue? How do I check that?

I’m trying guys
Thanks! Seriously

De soldered #13, soldered in another new switch, still no go. Does not appear in switch test, and both before and after switches still do. I guess I’ll try and source this diode, as to solder in a new one and see if that fixes it.

De soldered Diode and posted pics. Diode sheath looks as if it’s seen some heat, and the diode itself had a white dust on it. Cleaned the dust off as to make the letters and numbers legible. Looks like |N400| ?

Well I followed the white/green with my finger and eye balls and guess what. Broken wire. Going to solder it now and see if that fixes it!!!

WORKS!!!!!!!!!!!!!!!

So pumped!

Thanks guys xoxoxo

Maybe you guys can help me fix a problem that has existed for a while now.. doesn’t prevent game play but sure is frustrating on many levels and for several reasons...

Whenever I turn the game on it says adjust switches 52-55. The don’t work on switch edge test.. i pics of all the points of termination across that path. Maybe you guys see something I don’t?????

Looks like pics work from the left flipper to the backboard connector, in order as listed in the wiring diagram..

Thanks in advance!!

I don’t see it on my playfield schematic.... my uneducated amateur thought is that it might be in the backboard?

Im sure someone with more insight will chime in!

I’m still diagnosing my “adjust switch” issue for 52-56......

Ohhhh the skill shot!!!
