the medalist has diodes, so you'll need to be a little more careful when using continuity to not probe a place that will be blocked by one.
does your game have the fuse on the front of the reel assembly?
the reel wiper diagram and schematic is on
http://bingo.cdyn.com/slots/the plug charts are on the schematic.
a quick meter check is set up a single cherry win and look for continuity from wire 90 on the reel plug to wire 14-8 on the reel 1 contact plate
. See the w-1041-2649-2653.jpg file on the above web site.if your meter has a diode check mode and you have a cherry on reel 1, put the black lead on wire 90 and the red lead on wire 13 on the plug pins. You should get around 0.7V.
you could also jumper 90 to 14-8 on the reel 1 wiper contact plate. Then the game should detect a cherry win regardless of the reel wiper position.
if you need more info on what the wire id's mean or more details on how to do the above, yell.
