I just replaced my bill validator the previous ba30 didnt work at all. Now the problem Im having is no matter if I insert $1 bill or 4 quarters the machine acts as if the power was removed. The light on the validator goes off, I can see the ku-4156 relay move but only way to make the validator come back on is unplug and plug back in to the wall. So is the new ba30, trc 6800, ku-4156 relay bad, or something else.
