[QUOTE="Geoff1946, post: 523642, member: 28452"] Have you got a resistance meter, e.g. an AVO or even a cheapo multimeter? If you are happy to disconnect all the terminals measure the resistance between each one and every other one, if you understand me. It may then become evident how many windings there are and any hidden interconnections. DO NOT mix them up though. Make sure you can return it to present state then at least you wouldn't be going backwards! You may find they are all in pairs, or whatever results may be clues to its form. IF (BIG IF!) it's single phase there could be a centrifugal switch ? The only other approach is to take it apart and see what the inside reveals. That could be a good idea anyway to clean and lubricate it. You should also do an insulation test before any attempt to power it up. [/QUOTE]
