so i have a single coin machine that as soon as the first reel locks the hopper starts spinning and as soon as the second reel locks the hopper stops. the model plat has been removed so i have no idea what it is. i think its someones failed attempt at building a money honey. all the contacts look good all the wipers make good contact i think the pay cards are wired wrong for the reels but i don't have a schematic.
-
Do you have any knowledge of electrical troubleshooting? If not then I think you should leave it to someone who has it. It is not easy to troubleshoot and fix these machines.
There are a number of conditions to the hopper to be able to start, for example, the Wheels has stopped.

Yes i do have knowledge of electrical troubleshooting. In fact this is by no means my first em. I know normally the reels have to be stopped for the hopper to be able to start, but on this machine that is not the case. Thanks for the schematic but i have already gone through all the relays. I think my problem is the reel mech and hopper dont match or whoever re wired the pay contract cards has something crossed.
-
If you think the hopper or the real machine do not match the cabinet start with the hopper pull it out unhook the plug in the machine it plugs into undo the plug off the back of the hopper compare wire- colors
I have had Hoppers run with the first real index I cannot remember what it was amechanic was telling me he had the same problem last time I was at his house I do not remember what the problem was maybe he can step in if he still remembers I believe it was a shorted wire
And really in my personal opinion I can teach almost anyone how to troubleshoot these old machines even without knowledge they are that simple
-
I have worked on a lot of these things since starting with slots a few years ago, and for the most part they are easy fixes but latly the machines people bring me are butchered. Atleast now i have a set of test cables so i can get the mechs out of the machine for testing. I will check for obvious shorts again.
-
I would look at the A and the C switch closely
And then look for a shorted wire
-
I just noticed a switch mounted to the side of the coin mech. It doesn't look like anything can hit it and it doesn't seem to do anything.
Edit a and c switches were first thing i checked the tested ok with multimeter but i will look again.
-
The coin reject Armature activates that switch only seen on really early machines I have several of them here in my collection
-
Another way to tell is an early machine is the thought you only have two wires to your coin switch all the machines after 66 had three wires on the clean switch people figured out how to cheat and that's why they put the third wire just about all updates from that early machine on wiring is because people would figure out a cheat and the engineers had to rewire the machine around how they were cheating
-
I see how that would hit it now. The armature is missing on this machine.
-
If you go to my Facebook page I just uploaded a link for the schematic for that early 742a it's a little different than what you'll find in the manual much more basic and it includes that switch

Post a picture of your machine.. It sounds like you have a JPO or Jack Pot Only machine.. These were in the early Bally 800 series from what I've seen.. They would stir the hopper during the reels spin from time to time.. These are usually a Bar / 7 style machine paying larger jackpots..

do you want a picture of something specific?
-
No just wanted a front shot of the machine. You have some sort of Fruit machine and not a JPO. I would start looking for a wire grounding out under your reels. When you cycle your machine, the linkages under the reels come very close to the beau plugs wiring. Make sure nothing is grounding out when you play. I had a machine that the hopper ran 18 coin while the res spun. It turned out in my machine that there was a wire pinche'd and causing a short to ground at my hoppers plug. Once fixed my machines run fine.
-
The reels in it are not original to the machine they are crappy paper money honey clone strips someone put in it. i will check the wires under the reels again. Im about to call this one beyond economic repair and just strip it for parts.
-
If they are original paper money honey strips painted by hand to not stripping oh my God do not strip it it might be an early money honey let's get some pictures up here let me look at it please do not strip
-
No clearly inkjet printed strips.

"What we got here" looks to be a 742 compared to the photo attached.
I like this situation, not your ordinary problem. Wiring could be the problem.
How does a random stop on the first reel supply power to the hopper?
Why does a random stop on the second reel cut power to the first reel?
First check to see if the Latch Link. At the very bottom of the Reel Mechanism, is not pushing a wire on the Beau-Plug or any other wire.
If that is clear and good.
Then start from both ends of this situation and work into the first reel.
Find the wire that supplies power to the 3rd wiper board. Most of the time its solid gray and it maybe connected in two places on that board.
To find this wire NORMALLY, set up a three orange payout. There should be continuity across the boards and to the power supply wire.
There also should be continuity at beau plug. To test this, clip a meter to the pins that beep, then mover the reels one at a time.
The beep should stop every time.
Un solder the power on the 3rd wiper board wire and tape the end.
Try running the machine. Normally this would halt any signal to the payout relay.
Or from the payout relay, place a piece of paper between the contacts that supplies the power to the hopper motor. See photo.
This also will cut power to the motor.
Both of these test should narrow the search to the reels in a unmodified machine.
Note, I would do this on my machines, but please work at your own comfort level.

Good information i will try it maybe tomorrow im a little burn out on ems for now.
Attached is a picture of the other projects i have been occupied with.
-
Does this happen every spin? Do coins come out of hopper, or is override solenoid off when that happens?
Sounds like a mixer circuit built in, probably not a problem.
Try pushing your variator bar back to see if that duplicates the symptom.
