Choice vend HELP! Hi there new guy here just got my first Coke machine yesterday

[Mental Health]

  Like the title says got my first one yesterday off of Craig's list for $100.  All day I have been reading all the posts on this site and just wanted to say I have found a ton of useful info.  The machine I picked up is an early 1970's Choice Vend CVC142, it cools great but someone has done some hack wiring in it so only one button works and I think the relay for that button is stuck as well.  I am sure after tonight I will have a better understanding of what is wrong with it and if I have any questions I know exactly where I am going to go to get them answered  Will post up some picks as soon as I can and thanks for having such a helpful site!!!!

Thanks  I am working on this rig right now and I have a few questions concerning the relays...

I wired up the free play button but everytime I push it I do not have a chance to make a selection it just despenses from the fourth (last) cans.  I took the relay housing apart to watch the operation and there are six relays in there.  Four of the relays are for the vend motors which I am about to test (one works for sure LOL) and there is a hold relay which seems to be working correctly.  The question I have is that there is a sixth relay in there lablesd as an XR relay in the schematic, does anyone know what this relay is for and should it be energized as soon as you plug in the machine as mine is doing?

THANKS!!!!!

Here is a pic of the relay assy the RX relay is the second from the right in this pic... should it stay energized as soon as I plug in the coke box?  It only un energizes momentarily after it despenses a can.

Here is a picture of my awesome coke machine!!! I have wanted one of these for over ten years and decided now is the time I ain't gettin no younger

Wow I feel like I am talking to myself here LOL but just wanted to update that all of the buttons are in working order as are the relays, I really am starting to think there is something funky with the wiring to the motors or possibly the wiring to the buttons.

Can I possibly get a complete new wiring harness for this monster?

Yea sir all motors are operational I have been working on this thing for the last few hours and am not coming up with a whole lot.... It just wnts to vent frm the forth stack of can and no others.  I did manually jump the relay to the fist stack of cans and on dropped but the forth stack was running the whole time... Very confused any help will br MUCH appreciated.

I don't know that model but seems like machines of that era get cranky if low on product. Have you tried filling all of the stacks? Any "low product sensors" that might be missing or damaged. Sorry can't be of more help.

Yep you must have a minimum amount of cans in the machine before it will let a column dispense.
