Hamilton RNS-M-XE Jackpotting, i'm at a loss.

Hi everyone, I've had a heck of a time with our changer and looking if anyone has any insight. Initially noticed that it wouldn't take a dollar, we assumed we had a bad validator and sent it to the guy we have that works on them. Got it back put it in and ran a few dollars through and thought it was fine. A couple hours later I go check on it and its kicked a bunch of quarters out and not taking bills. No error code showing. Then we sent our hopper, controller, and validator(again) to our guy. He of course can't get the problem to happen again. Said he ran three thousand quarters through it. Get it back, same problem, works for an hour or two then it will take a dollar in kick it out, then not try and pull a dollar but still stay in service and no error code, then if I leave the power on it will jackpot all its quarters within the next hour. Checked all my connections and they seemed fine, then decided to just replace the harness, figured it had to be the problem. Nope, same result, work for an hour or two then refuse a dollar, then in a little while jackpot. I had a spare power supply so I tried switching that, same result. Had a spare hopper, same result. Validator, same freaking result. Its hard wired so I plugged it into a different power source, same result. Am I cursed? Any help or advice would be very appreciated.
Thanks

It's to bad you didn't come here first before you spent all the money on getting your changer parts serviced. I've seen this problem a few times, it is a rare problem. The problem is in the controller, when your controller gets warmed up the controller will run the hopper very slowly and dispense coins. An easy way to tell if the Hopper is slowly dispensing coins is the motor it will be very hot because only getting low voltage.

Sorry I realized now that I forgot to say that I also swapped the controller out With one out of another machine and had a similar result. I’ve had this thing apart so much and tried swapping everything except the stacker because that’s the only thing I don’t have an extra of.

You can take the Stacker off and plug in the Stacker bypass plug, it's cable tried to the harness that goes to the stacker, it's got a Purple wire on it. Put a box in the bottom of the changer for the bills to drop into and run it for a day or so to see if that isn't the problem. I'm almost 99.9% sure it's the controller.

Yeah I did the bypass and it didn’t matter. But you saying that once the controller heats up it leaks power to the hopper. That explains why every time I’ve messed with it I’ve gotten it to work for a little while then craps out, and why power cycling doesn’t help.
