Topic tags/keywords: voltage change craftsman motor 230-120vac table saw motor question

I bought a 40+ year old Craftsman 10” table saw with a 1HP motor. Previous owner had it wired for 230VAC. My shop only has 120VAC. I need to change some leads on the motor, but I cannot find any instructions to tell me what to do and Sears technical dept only looks at what is in the manual – this info ain’t there.

The motor has 3 terminals: T1, T3, T4. T1 has nothing connected to it; T3 has a BLUE and a YELLOW wire(s) connected to it; and T4 has a BLUE wire connected to it. There is another wire (BLACK) that is not connected to anything. I have to replace all external wiring as the insulation is cracked and falling off, so I want to get everything back in the right place and not fry the motor.

Can anyone tell me the right connections for 120VAC operation?

Thanks, Joe. I found the table saw manual on this site, but never thought to look for the motor manual there.
Now I just need to do a color substitution for what I have vs. what the manual says.
GREAT help. Really appreciated.
