Thanks,

Im not sure about this type of machine, but I have done some work on Wayfarer 2s in the past. Similar to that of Wayfarer 2s, id imagine the red/brown is positive, and the blue/black is negative. Sometimes 3rd and 4th wires could be for an external device such as a ticket puncher. Out of interest what colour are the wires? Id definatly imagine if there is red/brown and blue/black the red/brown is positive, and the blue/black is negative. If you have any pics that would be farely useful!
