Trying to get an ID on a machine first time restore

[Redwizard000]

Hi guys,

I am trying to get an ID on this machine I just picked up. It is a Nishijin, but I am not sure which. I want to find the proper manual and maintenance guides for it.

Best that I can tell, it needs new glass and some wiring work.

Thanks for any help!

You have a model B. It looks to be missing the lower ramp feed cover. That is needed to prevent ball jams. Also missing some dust covers...not needed so much.

The wiring is not needed.

Happy to see you rescue it!

you have a model "B" stuyle of machine

looks like your missing all 3 or the covers.. the track cover missing will give you problems.. the other two covers are probably not really needed

as for the wiring your missing the whole fuse block.. not a real big deal but it will make geting the lights to work a bit harder..

good luck to ya

and of course

Thanks guys. I got the machine from someone who had it in their garage for the last 20 years or so. I thought it would be a fun restoration project. The company I work for has free play pachinko machines in some of their stores, but they are all the new style machines with video screens and motors and such. I like the vintage machines best though.

I fired a few balls into it and they seem like they went through OK, though they are the wrong size (just some 10mm ball bearings I had lying around). I have some real balls coming in soon. Two of the balls I fired didn't make it all the way up and they got stuck in the outer half circle. I couldn't figure out how to get them out.

The fuse block doesn't seem like it will be that hard to either replace or work around. How hard is the track cover to source and replace?

Thanks again.

post a few pics of the stuck balls.. im sure we can help... (if you can post them to this (pachitalk) site they will be hear forever to help others like yourself..

take a look at these for track covers

http://www.pachitalk.com/forums/show...ht=track+cover

or make something like these i made for other machines

your fuse blocked probably looked like the center one below

Oh that is so perfect. I have a 3D printer, I am going to try later to print one.

And I figured out the stuck balls. Once I figured out how to get the glass front door to open I saw that what had happened is that there is an old rubber piece that broke in half and it was covering the chute. Someone tried and failed to fix it with a bit of blue electricians tape. I put a little dab of hot glue on the rubber and glued it to the bottom of the ring and so far it is sticking. Might need some better glue in the future, but for now it solves the problem. I would guess that the rubber part is to keep the balls from bouncing too hard against the underside of the ring as they come out the bottom.

As far as the electrical stuff, I think I might have to pull it all out and rebuild it. The wires are in really bad shape and the rubber rings holding the bulbs in are coming apart. It looks pretty simple.

Hello RW and welcome to the group

Might want this then.

Hey someone sabotaged this machine...

They cut a hole in the "loser ball" tube and a hole in the ball reject tray and glued a piece of wood in the loser ball tube so that instead of falling into a plastic bin in the back the loser balls go into the reject tray.

I fixed it though

Semi cyclic modification.

Some folks like that feature... (me!)

Purists do not like that feature. Oh well...

If you are handy with soldering, you can make the fuse block with some bread board. In fact, if you plan to power it with a wall wart, you can solder the appropriate receptacle to plug the wall wart directly into the fabricated fuse block.

I am replacing all the old 1970s lamps and wires with LEDs and I am building a driver on a little circuit board that I am going to power with a 9v battery. I am going to mount the board and battery inside the back of the machine somewhere.

Those little leaf switches are causing me some minor headaches, I am taking them apart, cleaning them and soldering new wires to them.

[hkp]

The leaf switches can be a real pain. If you keep getting intermittent contact with them, use some very fine sandpaper to clean the contacts. DeOxit works well to keep them from oxidizing again.

[Redwizard000]

One thing I am trying to figure out with regards to the electronics is most "B" models that I have seen have two lights and two leaf switches. One for the low ball light and one for the payout.

Mine has three. One is the low ball light. The other two lights are wired in series to what I think is the payout switch. I guess both lights are supposed to come on when the payout happens. But the 3rd leaf switch isn't wired to anything, the wires were cut at some point. There are no more lights and no more lights holes that I can see.

It looks like the arm that flips up to refill the jackpot balls is supposed to trip that leaf switch.

Anyone know what it is for and what it is supposed to be wired to? I assume there is a light missing somewhere.

Thanks

The arm in the ball reservoir moves up when there are no balls to weigh it down (low ball). The switch in the picture has the top leaf bent upward. The person that had the machine before you may have used it so that the low ball light would be on under normal play, and then go off when the machine was low on balls. That switch is supposed to close to light the 'low ball' indicator. My 'B' doesn't have a 'low ball' indicating 'flag', but another lamp that lights red where the 'flag' is found on most machines. The payout lamps are indeed connected so that hey both light up on payout. I didn't see 3 leaf switches in your picture, only 2. Where is the 3rd switch?

[Redwizard000]

First switch is at the top center above the jackpot circle, next to the payout load ramp (the ball low switch), and I did fix the leaf in the wrong position issue.

Second switch is on the left side of the machine. It is connected to the white counterweight with the pachinko ball built into it, I guess that is the payout light switch.

The third switch is on the right hand side about halfway down the machine. It is hard to see in the picture, it is covered by the plastic "loser ball" tube. It is inside a little cubbyhole. If you look at the "loser ball" tube you will see a long red-orange wire dangling there. Follow that wire up to the switch. The switch is connected to the white arm that refills the balls in the jackpot circle.

[hkp]

I just took another look at the picture. As viewing the picture, the switch on the right corresponds to the payout switch on my 'B'.The one a the top I the 'low ball' switch, the one on the left s connected to the payout lamps, but I'm not seeing what would trigger it.

The 'loser tube' is the ball dump tube, when you empty the machine for maintenance. Looks like there's a spot for a light in the center feature from the back, not sure an LED would spread light well enough to light it though. Where does the other wire from the 3rd switch go? Looks like there's one unconnected wire place in that junction.

[hkp]

On my 'B', that switch on the right is the payout light switch. It is normally open, and when the payout arm that releases the balls in the jackpot circle goes up, that switch closes and illuminates the payout lamps. I don't have the switch on the left side that is present on your machine Mine only as 2 switches.

The other wire goes into that little junction with the rest of the wires.

I am thinking that there is supposed to be a lamp in that hole in the jackpot circle and that leaf activates it.
