Lots of good advice,so I called Parker ENG this am,due to the close proximity of the
coin mech to the transformer dollar
coin is read as a quarter.I adjusted channel one counterclock wise slighty and it accepeted dollar
coins,but rejected about half the quarters. I then adjusted channel 3 clockwise ,which is the dollar slot,and it began accepting quarters.Problem solved! My Thanks to Doug at Parker Engineering and forum members for their input.
