[QUOTE="Perplexed, post: 3871657, member: 7157"] I recently acquired an Emerson 1/30 hp electric motor that came with four wires coming out of the housing, with the exposed ends of each pair twisted together. The seller didn’t know anything about it other than to say it worked when power was applied. I labeled the four wires 1-4; 1 and 2 were joined, and 3 and 4 were joined. 2 & 4 are thicker than 1 & 3. I tested for resistance between them all, after undoing the twisted pairs into four separate wires, with the following results: 1 - 2 = nothing 1 - 3 = 28.0 ohms 1 - 4 = nothing 2 - 3 = nothing 2 - 4 = 16.5 ohms 3 - 4 = 44.3 ohms I also tested the motor with the two twisted pairs 1-2 and 3-4 by applying 110VAC, and the motor ran smoothly for the few seconds I tried it. I’ve tried researching this motor online with no luck, so I’m hoping you electrical wizards can help out. I’m given to understand that if I switch the four wires 1-4 and 2-3, the motor will run in the opposite direction, but I haven’t tried this yet.
