Genco 1956 State Fair Rifle Gallery.

So found this example. Cabinet has been layered in house paint and bird stickers. Easy to mend.  Having some issues. Anyone has one let me know.
Thanks!

Hey ,Creighton

Nice Game !!

[Creighton]

Thanks!
It's not wanting to set to 000 on game start. Plays by itself or won't start at all. Lot of cleaning to be done still. It is like a change giver mech. Just look at it and think dang those guys were smart.

i believe Larry Wilson aka Grady, had a similar game he may be able to help you

[Larry]

I don't have that game, but they are all similar.  Before you try troubleshooting anything, take apart your steppers and clean them, including score reels.  It may not be resetting because it is gummed up.  If all is clean, and you have the same problem you may want to try giving the spring another revolution.  Assuming it is spring wound by one solenoid and reset by releasing the spring tension by another solenoid.

Manually check all your switches by making the relays open and close.  You could clean with scotchbrite or a burnishing tool to clean them.  Just make sure the switches are either closing or opening as designed.  You can adjust the switches with a contact adjustment tool. 

Schematic would be nice.  Check Pinball Resource.  They also have the contact adjusting.

Since it is a Genco you have a sellinium rectifier that may not be producing enough dc voltage.  Genco uses DC coils.  I still have mine, but it is recommended that they should be changed.

First thing is to clean.  Then adjust.  Then troubleshoot.

YEA !!! What Larry Said 

[Creighton]

Yea indeed !! Thanks Larry for taking the time to write that. Will call Steve in the am. The 1954 schematic on the web is not close to the "56" game.

Looks from what I've found this is 18 VDC out from the sellinium rectifier (I know test it but Fluke 87 batt is dead and on order). Anyone see a problem using a toothpick dipped in DeOxit DS5 to clean the finger contacts? Understand not a good idea on 50 VAC.

At $17 a small can not going to hose everything down. Just use where needed. Worked the charm on the coin mech and alum. pin connectors. Keeping it off any bakelite bits.

Pretty sure just dirty. Nickle is worn off the coin insert. Has had a lot of play but no mods other than the 15amp extension cord. That is first to go. Thinking 30amp CFI on plug for replacement?
Thanks!

I would use compressed air in as many areas as you can, then use a cheaper electronics cleaner like this one: http://shop.advanceautoparts.com/p/crc-qd-electronic-cleaner-11-oz.-05103/7070074-P?searchTerm=electronics+cleaner

See how that works, then use the DeOxit in the trouble areas, that'll save a little money.  If you can get between the contacts, some 400+ grit sandpaper usually works really well, spray a little electronics cleaner on it and give a light sanding.

They also make a small burnishing file for cleaning the contacts. I used them on my M-100 C Seeburg to clean the sets of contacts on the record carriage.
