Good day, gentlemen. I recently bought a Rowe 4900JR machine from a private party because they said it was broken. Well, I like challenges, and it was cheap, so here I am!

I was able to get it to work by replacing the coin mech and the wiring on the door switch.

The coin mec is a CoinCo 9340-L, and there is a BA30B bill acceptor installed in it. I have everything working except the bill acceptor. I bought a harness for the coin mech and validator, but I am unable to get the validator to work. It was quite a bit of trial and error to find the right dip switches to get the coin mec to work, and I am wondering if I still have some not set right.

I do not have a solid LED on the bill validator, but if I open the stacker, it blinks twice (which a manual I found indicates an open bill box) and the stacker tries to stack (also when I turn power on, the BA also goes through the motion of stacking), so it appears to have power. I am just not sure what to try from here.

Does anyone have any advice for me on where to start? I do have all the coin tubes full.

Thanks in advance.
