Rebuilt a pool motor for a friend from bits and pieces (the windings were sound, front bearing so rusted in I had to smash the front plate and grinder the shaft in half to save the circlip for the bearing). Found a used plate and rotor shaft, replaced bearings, its all running.
But I have a nagging worry -- the notes I took when disassembling vanished and it's one of the new (crap quality) Quality pool pumps, so just uses one of those chocolate block terminals for the wires, no proper marked terminal with lugs.
It runs anti-clockwise -- is that right?
There are three wires - Red, Black, Blue. Between Blue and Black it's 8.6 ohms, between Red and Black 4.5 ohms, and Blue and Red is 12.7 ohms.
So that would suggest Blue-Black is main motor winding, Red-Black is starter winding.
Live would go into Blue, Neutral out of Black, and through the start/run cap from Red to Nuetral. That right?
