I just bought a replacement fan motor brooder house exhaust

Customer Question

I just bought a replacement fan motor for my brooder house exhaust fan. The old Motor had 2 speeds and 3 wires, red, white and black. This new motor 3M505J has me totally confused. The instructions on the motor says the following:
High Speed Low Speed In the Motor there is just a plate to screw
Black T1 Black T1 Wires to:
Red T2 Red T2 T1 Has a black wire from motor
Line 2 L2 Line 1 L1 connected to it.
Line 1 L1 Line 2 L3 T2 Has a Red wire from motor
connect to it.
L1,L2 & L3 have screws for
wires to.
T3 is a stub for a slip connection.
How do I attach my red, black and white wires to this motor? The instructions don't say anything about the white wire.

Hello, use the paper clip icon at the right end of the tool bar above, or the 'attach files' link to the left of your send button to send me 4 or 5 photo's of the motor wiring and hopefully the paper wiring diagram glued to the side of the motor.

photo's need to be well lit and well focused.

We can go from there.
