Leeson 2hp motor no plate rewire from 120v to 240v

Leeson motor 120V to 240V no tag Hello..I have a Leeson motor with Auto reset overload protection and Start Cap/Run Cap ( 2) and I need to rewire to 240V BUT..I am not sure how it is wired now or if it is possable..THE plate is missing..No schematic anywhere..What I do have inside the motor wire connection box are 4 wires labeled P1, P2 and T4 , T8..All inside wires are Black... At this time P1 runs to a large brown and a small purple wire..P2 runs to a small purple..T4 and T8 are together and run to a large blue wire.If there are any other wires they are not visible in the wire connector box...When I plug in the Lg Blue and Lg Brown the motor runs and sounds just fine on 120V.. The 2 small wires, Purple and Black run to a connector/plug and seem to do nothing..I am trying to install the motor on my Jet 14" band saw that has cut less than 200' of Cedar and died..All tools in my shop are 220V and all of my extension cords are 220V so I want to keep it all the same..ANY help will be greatly appreciated..I have tried to find anything on Leeson web site but no way..The only #'s on the motor are (__)16440 03 ( the (__)= not sure) ,,and also A6K34.. The capacitors are Motor Start Cap is 250VAC and the Motor Run Cap is a 12.5 UF 370VAC...THANK YOU for your time and effort..John

Good morning, problem began when timer stopped working at the pin "off" point. Figured a new timer was in order so replaced with a WG1573-5 (same as previous) Timer is T104. Now the problem, when the timer...

Did you buy new timer or new clock motor?
WG1573 is replacement 240v clock motor for T100 series timer.
T100 series is fully repairable and can be maintained to last decades. I've seen operable timer from 1950s.

You can convert T104 240Volt timer into 120V timer by changing clock motor to WG1570 to replace WG1573.

In any case, timer is wired wrong somehow since it seems to cut off one leg of the 240V circuit.
Copy following links for illustrations and troubleshoot and more information than you can use in decades:

Don't grind up your motor.
Connect direct to hot wires and run 240V.

240v circuit to 120v pool pump

Listen - you had three wires feeding your old 240 volt pump. Two were hot and one was a ground. To run your new 120 volt motor just connect one of the two hots to the motor along with the ground. Cap off the remaining hot wire so nada bad happens and you are good to go.

I have a kobalt 60 gallon 3.7hp air compressor, I was using a dryer plug prevousily but I know longer have access to one, the motor says 208-240v is there a way to turn this into 110 or should I just get...

Ya you'll need another motor or a new 240v line. If it were a voltage switchable motor it would say so on the tag. I have an air compressor with a switchable motor and it says 120V/240V on the tag, theres a wire to remove inside the pressure switch to change the voltage.

What happens to a 240v electric motor if you hook up the same phase 110v to each of the 2 lines

It will not run. With only one wire hooked to both leads there is no potential and no place for the current to flow to. electric bruno.

How to wire a intermatic timer T104 240 v to a 120v?

T104 is 240volt timer.
Timer has terminals A 1 2 3 4
T-104 clock motor must receive 240Volts to operate.
Clock motor wires are white-colored and can be seen connected to terminals 1 and 3.

There are two work-arounds for using T104 for 120V.

1) Diagram 1 showing how to change wiring:
Move 240V clock motor wires to terminal 1 and A.
Connect 240V Hot leads to terminals 1 and A. This will power the 240V clock motor
Hot wire going to 120V load connects to terminal 2. This wire will be turned on each time timer turns on, and 120Volts will power the 120V load.
To complete 120V circuit, neutral wire that comes from neutral busbar in breaker box connects to 120V load.

To control additional 120Volt circuit, run jumper wire from terminal 1 to terminal 3.
Connect Hot to second load to terminal 4.

2) Second method is to change T104 timer into T103 timer:
Replace T104 240V clock with identical 120V clock motor from Grainger
Neutral wires connect to terminal A.
Hot wire from Breaker connects to terminal 1
Hot going to Load connects to terminal 2

To control additional 120Volt circuit, run jumper wire from terminal 1 to terminal 3.
Connect Hot to second load to terminal 4.

How do I wire an intermatic t-103 timer switch

The T-103 has a 120Volt clock motor

From there, the wiring can go two directions depending on your Load voltage (load is the fan, light or motor that timer turns on-off)

Here is a link that shows exact wiring:

When wiring the T-103, steps 1-2-3 are true for 120V or 240V installation:
1) A white Neutral wire is always connected to terminal A (Neutral wire connects to Neutral busbar in breaker box)
2) A black Hot wire is always connected to terminal 1 >> this hot wire can come from 120V or 240V breaker
3) Black wire going to Load (fan, light, motor) is always connected to terminal 2
The following step is true for 120V Load
4) if Load is 120V, then white wire from Load connects to terminal A
The following steps are true for 240V Load
5) Only the neutral wire connects to terminal A as described in (1
6) The second Black hot from breaker box (240V has 2 hot wires) connects to terminal 3
7) The second White going to Load connects to terminal 4

Here are 2 more links that show how 120V and 240V circuits are wired
