I bought a new motor for my pool an AO SMITH B855 2 hp but I neglected like so many others to tag the wires. Problem...I have the green ground wire but both others are black. Diagram is L1 and L2 both have two terminals. L2 has a white wire attached to one side. I also have one terminal B that stands alone at the top of the motor and terminal A that also stands alone at the bottom of the motor. I'm sure it matters which line goes where? Help?
I am assuming you are running 110 vac. Usually there is a diagram on the plate with the motor specification. You want the low voltage for110 and high for 220 motor wiring diagram you connect the motor as shown. If it is not on that motor it maybe on the old one they are usually the same.
You will need wire nuts to tie together the wires.
Note if this is a capacitive start or switch start. Allot of pool pumps are Switch start.

The L1 and L2 are the load terminals. Connect the black wires to the L1 and L2 and the green one to the green colored screw.
