Does anyone know where to get a vend relay for this machine. I have a nice machine been sitting in my garage for past 8 years. I can get it to cycle by manually holding the relay. Tried cleaning contacts with fine sand paper but to no avail. Part number is Y-48830. Coinco coin mech also won't empty the nickles when you hold the payout switch.  Where is a good source for parts? Thanks for the help.

Sigh.... newbies,   :glare:  OK... get out the spoon.  :tounge:

You really ought to include a picture of the part in question,  maybe someone might recognize it & let a helping hand.

Insofar as your coinco coimech also include a model number as there are a multitude of different models for all of the thousands of vending machines in the past & present.

But overall, this should be an easy fix ( both problems) , we’ll just need a little more info.

       If I'm not mistaken, that vend motor replacement has been difficult if not impossible to find .                                     

He mentioned the vend relay ( credit relay) actually, not the vend-motor,  unless he misspoke?

Newbie that's me. Thanks for replies. I tried posting a lousy pic of my machine last night but was rejected cause it was too large. I will try again. I will eventually get pic of vend relay ( I have to disassemble again) and coin mech if necessary especially if you guys can help. The coin mech label doesn't have a model that I can see. Part of the tag is missing/worn. However, I have done some research since I last posted. Per sodajerks.com it looks like they have the vend relay for my machine, it is part #EP27A per their website. Same is true for the coin mech. They say it is part # EP21 and it looks just the same as the coin mech in my machine. (my research looks like coin mech part # S75-9800A)

Before I order anything I will again try to clean the relay. Found some electrical cleaner in aerosol can that they say can be used for cleaning relay. I would also like to disassemble the payout motor assembly to see if it is somehow jammed.

This machine was a rebuilt/reconditioned one. I inherited it but only now have time to get it working.
Thanks again.

I could not find a jam in the nickle column , the payout still does not work. Could not clean the contacts on the relay well enough to work. Somehow I did get the machine to vend one bottle - what happened I don't know. The coin mech is made by Coinco. The vend relay is made by Artisan and has RH 206 and Y-48830 written on it.
I think these 2 items are my main issues in getting this machine to work. Appreciate the help. Still can't post photos - too large, this time used my iphone camera??

If the coinmech is defective, then it won’t trigger the credit relay to allow a vend...

You said your coinmech wouldn’t work when you tried to operate the inventory switch to eject the nickels used for giving change, this may mean your units ( coinmech) internal 12-volt power supply is bad from either a blown fuse-link on the circut board or a bad zener diode regulator and / or its filter capacitor, this will also cause the coinmech to accept coins but not “count” them ( and therefore not giving the machine a “credit” to allow a vending cycle)

So what looks like a bad credit relay, may not be....

Check the circuit first by unplugging the coinmech and jumper  pins 1 & 3 of the female “jones” plug that the coinmech plugs into, use insulated wire & be careful because the entire vending circuit on this machine is power by line voltage (120 volts)

Thanks JohnieG. I did what you said. Results are that it looks like the vend relay energized but no bottle was vended. My guess is you just proved that my vend relay is good/ok.
Here is some more info from more messing around last night. I am able to vend bottles from each of the 6 selections if I just move that plate on the vend relay. It seems like it is only partially energized meaning that all I have to do is nudge it up a little and then it fully energizes, clicks into position, and then vends a bottle. Problem is too that it is always ready to work if I just help it (the relay) - no need to put any coin through the coin mech.
So maybe all my problem is with the coin mech? I'm ready for next assignment!       

I would gladly spend the $150 or so for a new coin mech if I could be sure that was all I needed to make this machine work. Is there a way to jumper the jones plug to test the machine? Thanks.

Well , I am getting closer. After I jumper the 1 & 3 on the jones plug , as I said it then energizes the vend relay but no vend action. However I then plug the jones back in and wa-la.... I get vend action-bottle comes down!!! So it must be my coin mech that is bad. I would guess that if I had a good coin mech everything would work ok. I think I have seen rebuilt ones for $150. Talked with Funtronics today and they do not rebuild them anymore. Any thought are appreciated guys.

I read further about free vend. So in addition to the jumper wire on the jones plug of 1 & 3 suggested by johnieG, I also jumpered 1 & 7.That gave me the vend. So that proved to me the coin mech is bad. I just ordered a newer S75-9800 coin mech that has nickle/dime payout which I understand is a little bit newer/better than my older one that is just nickle payout.   To be continued.........

Got the coin mech in the mail today and installed it. It works! There are just extra 2 electrical plugs (besides the jones plug) on this new coin mech that I don't know what they are for - maybe for a different machine. There is also an electrical plug attached to the machine under the selector panel that I don't know what its for either?
The only thing left is to figure what bulbs go into the signal lamp box for "correct change" and "select another drink" Manual says part # 1377175.

Hey, am I still a newbie? 

The two smaller plugs on the coinmech are for a dollar bill acceptor, which you don't have anyway,
I attached a pic of the correct “S6” 6watt/120volt indicator lamp that you should use in the correct change only & select another drink indicators, the xmas light is for comparison of the shape differences  between a “C7” & a “S6” bulb, dont use those cheap LED “night light” replacement bulbs, as they’re not bright enough & don’t illuminate the indicators properly in my opinion.

Insofar as the mystery plug behind the panel, you might wish to post a picture, it may be for a light up sign option (brand marquee) your machine doesn’t have, does it have a metal or a plastic sign?

Thanks johnieG. Makes sense to me regarding the dollar bill acceptor. And I will shop for light bulbs tomorrow. I have the metal sign . Maybe a light would be to, as you say to light up the drink selections/options. There appears to be opening slots at the bottom of the drink options labels where light could enter. 
Can't figure the attachment of a picture on this website yet as it says 200kb max for picture. All my pictures are bigger. The mystery plug has 3 round openings but only uses 2 ( 2 wires) so maybe it is power for a light.

Yep, that’s what the extra plug is for on your machine, the light up sign option,

Home Depot, Lowes or Manards ( or most other big box stores have them, just make sure the bulbs say they’re for 120 volts, ( some modern appliances use the same style light, but they’re only 12 volts) just double check the specs on the packaging.

In fact Im finishing up a deck for a Westy’ WC-60/MD for another customer today.

Yes, got the bulbs at Menard's as you said and they work! This old machine is beginning to look good. I am just waiting for a few decals that I ordered  to make it more authentic. I am going to have to move it from the garage to my basement.
By the way that is some good looking work on your customers machine, way above my pay grade. I guess I will be a newbie for a while. 

Be careful ! ! !  As you well know, this is one heavy machine ! ! !
Appears to be a nice original machine too!

You are not kidding, it really is heavy. Lucky there were 3 of us. It looks like there might be a possibility of making this lighter the next time around. You could remove the door except for a bundle of wires that goes from the machine to the door. Couldn't you install some sort of quick connect/disconnect  similar to what you would find on your car electrical system on this group of wires? The door might be 20% of the weight of this machine?  Anything helps.
