Question on Wiring for 25 Cent Coin Hopper

[DB26]

Hello everyone. My machine was having an issue with the hopper always reading full and diverting the coins to the overflow / drop. I was looking at the wiring on the hopper and decided to try an experiment.


Now, I knew that the coins only divert when one of the hopper wires is grounded, telling the comparitor that it is full. I moved a few of the orange probe wires around trying to get the diverter to shut off, but didn’t get anywhere. I saw my hopper had a green ground wire connected to a nut near the probe wires. On a hunch, I removed the green wire and my diverter has now shut off.


The hopper is still functioning correctly.


My question is, was the green ground wire attached to the correct location? If yes, where else should I look as to why the diverter was energized? And if no, where would the correct location be?


The photo shows the green wire and where it connected to: the red line points to where the nut was securing the wire.

The green wire is a ground. It goes where you have the orange/green now. The orange wires all go on the probes. Your upper probe (the long one) is missing. When coins or tokens contact the upper probe indicating the hopper is full, they will divert to the overflow chute. The 2 tiny probes indicate when hopper is getting low.

Great! I’ll correct the wiring. So does this mean the orange/green wire is the one that is supposed to have the long probe?


And that would mean from top to bottom you have the orange/green, blue/orange, and purple/orange.

Yes the orange/green goes at the top. I think the other 2 are correct. The probe is basically a brass 10-32 machine screw with a star washer nut on it about 1.25" long.

Thanks RB. Here is a photo of the current configuration. I’m happy with it! And the diverter no longer engages. Perfect!
