I'm rebuilding a Comet ex a deceased VOC member and found potted into the Miller cover a regulator, 3 wire output (Brown, red, orange). There are stainless hex bolts (5BA?) on the shorter sides and the base of the regulator is a stainless plate with six, 6 star (6 way) socket screws attached to a plate which disappears into the potting compound. Difficult to photograph.
Assuming that it's actually 6 volts, from the 6v bulbs in the headlamp, how do I determine what polarity the battery should be (-ve or +ve earth)?
see pics
bike doesn't yet run but hopefully will soon
don't want to destroy the regulator by driving it in reverse voltage
If it was made by a particular supplier, can they help? (the ex-owner kept no records and had the bike for many years)
