I don't have much info on that game, tho I have a picture of a piece of a 1093 schematic that shows a reel mech A switch in the circuit to the coin switch. The A switch has yellow wire 30 on one blade and can't tell the other color ... maybe orange/green.
a few machines made for denmark had circuits for a stand. If the game wasn't on the stand and wired in, a dummy plug needed to be inserted into a socket.
usually that plug is in the cabinet behind the reels, and without it the coining circuit is dead. big_e posted a picture of one a few months ago ...
http://newlifegames.com/nlg/index.php?topic=32199.msg170949#msg170949one of the things the dummy plug does is jumper wire 30 to 90-4 on the socket, so if you have the socket and no plug, jumping those two wires together will probably make your coin switch work. Wire 90-4 goes to the coin switch. For example, see the 929 or 917-1 schematics on
https://bingo.cdyn.com/slots/ have no idea what the hopper board is for or the connector wired into the top. You'll probably have to trace wires and see what game wire colors are connected to those things.
finding a schematic would be really helpful :-)
