Hi,
I've been searching the forum, and see it's recommended to connect to the jones plug for the free play with a 9800A.

Just want to see how/where you connect the wires too, in a real pic? 

Thanks.

Anyone?

Are you just pushing the switch wires into the harness,and then pushing the jones connector on?

Or are you tapping in someone else?

      I think they just push the connectors into the harness, and do
away with the entire Jones plug and coin mech.

Here's my free-vend switch I used to test the gate in my machine.  If you're wanting to use a jones plug and aren't sure which wires go where, your trusty mult-meter will be your answer.  Just ohm them out man.  :biggrin:

Witchboard's photo depicts an excellent view of this concept; however, for everyday use, you can utilize an encased two-wire cord routed to a momentary switch mounted somewhere accessible for operation.

      Also, by cutting the jones plug off a useless coin mech, and extending the wires and adding a momentary switch allows testing of vend columns with the door wide open.
I use this tester on every machine I get, bypassing the coin mech saves a lot of time.

Thanks,
What I want to do tho, is keep the coin mech but hide a free vend switch too.

I don't see how to do this and keep the coin mech too. 

Utilize the wires on the underside of the Jones Plug to tap into...

Not sure what you mean by the wires on the underside of the plug?

I guess i should take a pic of mine, to show what I have. 

I think what Jim is referring to is the wires leading to the Jones plug socket.

Here is how my plug is,

The only thing I can think of is, trace the wires into the mech itself and tap into them there?

Also, I was looking at a thread, and it had a diagram of the plug.  But I noticed that it's 1 and 2 , and 7 and 8 pins were opposite of mine?   Is that OK?

Unplug the Jones Plug, then remove the glavanized box that houses the Jones Plug Socket. Once removed or just remove the screws holding it to the cabinet door, then you can access the wires from insode this box...

OK,
Got it all wired up, I push the button and it vends a pop.
I put in a nickel (It's set to .05) and it vends a pop.

But now get this,
I put in a dime, and it vends a pop and gives back 2 nickels!!

argh!!
I get so close every time I mess with it.

Any ideas?

Just tried it again with a quarter, and it now shoots back 5 nickels.

Any ideas what I did wrong?

I know it's set to .05 because it vends on 1 nickel?

Sounds like a trouble-shoot job for none other than our own JohnieG ! ! !

Hope he can help, this thing is driving me crazy.
Every time I think I have it all setup and working the way I want it.  I find something else odd, about it (lol)

Right now it's a change machine  :biggrin:

Sounds like you have to pay each patron a nickel to buy the soda! j/k
 :wow:  :tounge:

anyone have any ideas to where I should be looking?

I'm just starting this process... looks like this topic has not been active for awhile. I keep seeing messages that say things like, "pushing the button makes the machine think that  a coin was inserted..." My question is, Which coin does it think was inserted? I.e., does the jumper between 1 and 3 signify a specific coin (quarter?) and other jumpers would mean other coins (nickels, dimes), or what? I will be trying this soon... just wondering...

The coin mech does all the math when you put money in. Once the proper amount is inserted, it sends a signal to  the jones plug. One pin is neutral, and one is the hot signal. By putting in the switch, you are bypassing the coin mech..

This thread may be helpful.  There are wiring diagrams and several Q & A about the topic.

Sounds like your Coinco 9800/A series coinmech has a power supply issue that may be  causing the CPU/chip to overcount/ miscount the coins, remove the slug rejector & make sure you really & truly have the price switches set for 5-cents, first switch should be up & the rest of the other switches should all be down. then carefully trigger the nickel switches wisker-wire with your finger & see if it counts properly, then try to manually drop a dime down the dime-slot, & see if it gives back a nickel in change, then try the quarter slot, etc.

Thanks... I have played around with this a bit and think I understand how it works. Momentaritly connecting pins 1 and 3 trips the relay/solenoid, which stays tripped until you select a soda.

I have a question, though. Connecting pins 1 and 7 does not seem to have any effect. Based on some previous posts, I was hoping that connecting 1 and 7 would "lock out" any coins.

My machine's normal behavior is to accept 50 cents and then if you put in any additional coins, they just fall through to the coin return, until you select a soda. Momentarily connecting 1 and 3 makes the machine act the same way. If you put in coins after tripping the relay, they just fall through until you select a soda. So far so good.

However, based on some earlier posts, I was hoping that shorting pins 1 and 7 (persistently, not momentarily) would provide the same behavior. I thought I understood that it would "lock out" the coins and they would just fall through, the same way as described above. However, connecting pins 1 and 7 on my machine does not seem to have any effect. It still accepts 50 cents and then locks out additional coins - basically the same behavior as if pins 1 and 7 were not connected. Did I misunderstand or is my machine behaving differently for some reason?

I'm trying to do something a little different with my machine. My machine (Vendo 475) is in my business - a print shop - and I want to be able to put the machine in "pay" mode or "free" mode using a keyed switch. I was hoping that the switch would, among other things, enable the momentary pushbutton to trip the relay and get free soda, but also connect pins 1 and 7 and lockout anyone from putting money in the machine - like if they didn't realize it was in "free vend" mode. I will upload some pictures and schematics of the circuit I designed for this, but if anyone can shed some light on the issue described above re: pins 1 and 7, I'd appreciate it. Thanks!
