1974 Bally's Big Time nickel slot machine (1015)

[slangyeti90]

Hi folks, I am looking to sell my dad's slot machine for him that he acquired through trading labor. When we received it the 110v plug was trashed so I made a quick fix and thru some wire nuts on a new power cord. Works great except I cannot figure out how to get the machine to fully function. I am not sure if this is a quarter or nickel machine either. I checked the fuses and they are in working order, but I did not replace them.

I am attempting to find some information on this machine to see what it is worth. On the inside on the hopper it states that it is for $0.25 but on the front it shows 5c. The model number on the inside shows 1015 as well. If anyone has any information about it I would greatly appreciate it. He traded some labor for $500 so I am not sure what we are working with. I have only been able to find the $0.25 version online without the upper half of the machine. I am also look to find someone who has the knowledge to help me fix it as I am a mechanical engineer and feel that once someone can view the photos and video of the issue it would be simple to diagnose.
New to the forum, thanks for your time!

slangyeti90,
Your problem relating to the photo noted below could be various things as a coin entered should "trigger" the coil to allow the handle pull to start the game and not doing so could be a broken wire, cold solder joint, a beau plug pin not making contact, a leaf switch on the side of the reel mechanism, a proper reset issue on the hopper, Etc.
Contact me by my direct email and I can send you a diagnostic guide and further information in that way!
Also, where are you located and FYI NEW LIFE GAMES may be a better site to seek more information as they deal more with the later electronic slots while primarily here the older vintage mechanical slots are discussed!
