Change machine help

[Allwash]

So I’ve got an old change machine that’s not been in use for years and I want to try and get it going again. From my knowledge it was shut down when the place stopped accepting credit cards and coins in the bays but that was before I was here. It’s a standard change makers brand and the model is sc22-rL with a sc-max conversion kit in it. It’s currently stuck on hoppers a,b sold out and I’ve tried all I can think of, I’ve filled it passed the metal sensors in the hoppers, I sanded the sensors aswell, I tried jumping the sensor wires to bypass it, I cleaned the grounds and cleaned the photoeyes ,when I press dump on the controller it works normally like it should and shuts off when out of coins so I’m not sure where else to go so any help is nice

I would probably call Standard tech support and ask them what the problem could be.
If you don't have the manual here it is http://www.standardchange.us/manuals_pdf/8M00601-SC-MAX Conversion Kit Install_RevA.pdf
and another manual https://standardchange.com/wp-content/uploads/2021/12/8M00622-SC-CONV-KIT-INSTALL-INSTRUCTS-Ver3.pdf
