I have a SB9 with a 1/3HP motor (an older Delta/Rockwell/Marathon motor).
My starter cap recently died, and I thought while I wait for the replacement to show up, I'd decipher my wiring and try to see how difficult it would be to swap in a newer Dayton motor.
Let's start with the easy part: my Furnas switch.
Now here's how it's currently wired:
To me, CW and CCW are not intuitive, as the motor plate describes (CW) as how my motor is wired when the switch is in reverse. So the older standard must define CW/CCW as looking from the NON-shaft end of the motor?
If that is true, great. then I understand the wiring as diagramed above. I assume then that the "black" and "blue" wires coming out of the motor are the run winding, and between terminals 2 and 3 is the start winding. (but this is where I could use some confirmation...)
Next I'll draw up my Dayton motor - that has everything going to a terminal block under the motor cover plate. Even if my cap arrives before I get this figured out, I'd STILL like to better understand this, so I can swap out for a 1/2 HP motor down the road.
Thanks in advance!
