HELP: Modifying vending machine to be Free?

Hi, community, thanks for inviting me to the Forum.

I am an electronics technician, and a couple friends of mine asked me for some help with vending machine. The story is this is a Frat house, they bought an old Coca Cola vending machine that they keep in the frat house, that's been sitting there for a while, and they want it to work without having to pay and fill it up with beer cans.

I went to diagnose the unit, seems to be working fine, except that the mechanism to count & hold coins is missing, coin just drop from top to bottom.

As per the schematic looks like the thing I am missing is called a credit relay which is probably part of or the entire coin mechanism

I have attached some pictures.

I am wondering if anybody knows how the credit relay works? can i just add a jumper somewhere so that the machine is always reading "infinite credits?"

Everything else seems to be working fine, swtiches and relays, buttons and LED's.

I'm attaching some pictures

There's 1 open 9 pin connector, thats where the coin mechanism goes. I feel I could put a jumper there, if I understand how the coin credit relay works

Any help much appreciated, I'm going to attach more pictures.

Comment and I'll pm them to

Comment and I'll pm them to you or your email. I feel that all coin mechanism must be pretty similar, perhaps. The solution might be easy. Something like jumping voltage pin 5 to pin 3, for example.

Thanks.

How to Set Soda Vending Machine to Free Vend

If your soda machine is not to old (10 to 40 years old).
Here is a link to a post on our forum with detailed instructions and diagrams on how to set your soda vending machine to free vend:
https://www.vend-resource.com/forum-topic/how-do-i-set-soda-machine-free...

Note:
If it is real new, it uses a cumputer control and you need to use the machines programming manual to set a selling price of zero ( free vend ).
If it is really old you will need to goto one of the antique vending machine restoration forums and they might be able help.
Let me know if this helped,
