I am about to replace my old motor with a V-Green 1.65 HP Square Flange 48Y Variable Speed Motor, but found that there is no ground (green) wire attached to the old motor. There are only two wires, connected to L1 and L2. Outside of the tube for the wires that goes to the timer, there is another wire that is winding around the tube. It looks that one side goes into the ground, the other end goes to the timer box, but not connected to anything. So, I guess this wire is not used at all. I searched the posts here and it looks that it is not uncommon for very old motors to not have a ground wires, but did not find out solutions. So, must the motor be grounded? If so, how should it be appropriately grounded? Thanks very much!
