Help!
I'm working on a bb1 that I purchased parts complete and I cannot clear the bill val com error, So far I ordered and replaced the bill validator complete. (wba-13 and communication board) from Spin. Then I replaced the cpu and backplane, the bill val wiring from the bill val to the connector on the machine and still nothing.
I have the backplane jumpers set on 2-3 as per the manual. The bill val does not even cycle on startup, when I open the top one of the scanner lights is on but that's it.
When I got the machine it had a uba-24 in it and had the same problem.
Any ideas what I could be missing?
