Vf117d-sar vendorlator 7-up

I recently purchased this machine. Currently I am looking to purchase coin op mech. This is only item missing from machine when I purchased it. My question please is as follows. I can remove a bottle from the machine now without placing the dime into machine. Once I place the coin op mech in machine will it automatically lock the bars to prevent taking bottles. Also the small bulb that sits behind the refund sign. 1"x1" inside the coin box is not working. Does the 9 plug coin op need to be plugged inorder for the bulb to light. First machine at a total lost. Frustrated new 7-up owner. lol.
Thanks Dave.

Dave, don't get frustrated. That's a very cool looking machine. Congrats!
The mini bulb may just be burned out and can probably be replaced with a 4W nightlight bulb.
The standard Coinco mech would probably be fine.
Perhaps it is rigged to be on free play. Once you put a coin mech in it, it should lock the vending until a coin is inserted.
we eill all help you a ton here. We look out for each other.
