So apparently I committed a cardinal sin when I took apart the jackpot mechanism in one of my Victory frame machines and cleaned it. I put it back together and now it gives me an error 4 fairly constantly. Anytime the machine fevers it will pay out a few jackpots and then error 4, often refusing to reset with the button. Here recently it has gotten worse to where it will error every few jackpots it pays regardless of how frequently the jackpots come or which machine I put it in (I have 3). Anyone else have this problem ever, and know how to fix it? Does anyone else have a working jackpot unit from an otherwise kaput machine that I could replace it with?
