I'm running myself ragged trying to figure this out. I can get the mech to vend and return regardless of how I configure the coin options. If I set switch 6 to escrow to vend, then vending works but I can not hit the coin return and get an escrow return. If I set switch 6 to escrow to select then I can get an escrow return with the coin return but when I satisfy the price the block-out LED stays lit and it won't vend. I've tried all combinations of high/low quarter, bill acceptor and it will either not accept the price and return or not allow a coin return but vend.
Any ideas??
Thanks!
