On this Dayton motor T6, T7, and T8 have continuity. T7 is connected to centrifugal switch and the other non-labeled wire from the centrifugal switch is connected to the start caps. T4 and T5 are tied together to L1. T8 and T1 are tied together to L2. The run caps are tied in series with the run windings(T4,T1). Where does T6 fit into the wiring?

First of all...
The "run caps" DO NOT go in series with the run winding, they are in series with the start winding and at the same time in parallel to the start caps and the start switch (which ARE in series).
Draw it like this.... THREE items ALL in SERIES... "start capacitors" to the "start switch" and then to the "start WINDINGS." Then the RUN CAPS are in PARALLEL with the "start caps" to the "start switch" part of the start circuit.
Following your description...
"On this Dayton motor T6, T7, and T8 have continuity" And T8 goes to L2.
OK...L2 to T8 which connects to T7 and T6.
"T7 is connected to centrifugal switch and the other non-labeled wire from the centrifugal switch is connected to the start caps."
OK...we now go thought the start caps to what I will call... POINT "X," (the other side of the start caps). Point X then HAS to be connected to the START WINDING. The start winding then FINISHES at T5, which is connect to L1.
"On this Dayton motor T6, T7, and T8 have continuity." T6 then connects to one end of the RUN CAPACITORS and from the other side of the run capacitors we connect to POINT "X."
That completes the motor you described to make it work, but I think you will find it will not work since you say "On this Dayton motor T6, T7, and T8 have continuity," and probably have not physically checked to see what those three leads are connected to internally in the motor. I suspect you will find a few ohms of resistance between T8 and T6 & T7. Till you give a more thorough explanation of how everything is connected I will leave you with what you described.

If you can tell me what you left out...
What T5 is connected to and now many ohms it has?
Does T1 and T4 have continuity to anything else and if so, how many ohms?
How many ohms between T6, T7 and T8?
I can give a much better description of how your motor is connected.

The resistance from t7 to t6 is 1 ohm.
From t6 to t8 is 2.3 ohm.
From t7 to t8 is 2.3 ohm.
As I suspected... T8 is directly connected to the start WINDINGS.
Now that T8 is one side of the start winding, that leaves us with T6 & T7 connected to the other end of the start winding.
The resistance from t7 to t6 is 1 ohm. The 1 ohm is more than likely just the resistance of the ohmeter's leads and can be ignored since T6 is directly connected to T7.
Let's look at the complete start winding CIRCUIT beginning at T8 and ending on T5.
We now know that T8 is the start WINDINGS and that the those windings FINISH at T6 & T7.
As you explained... "T7 is connected to centrifugal switch and the other non-labeled wire from the centrifugal switch is connected to the start caps." This has to END at T5 to complete the T7 circuit.
Which leaves us with your original question "Where does T6 fit into the wiring? "
T6 is where the RUN CAPS are connected to the START windings.
So T6 connects to the run caps, goes through them and then finishes up being connected to T5.
I hope that expalins it for you.

On a cap start run motor, are the run caps utilized by both the start windings and run windings?
The more theoretical guys would have the correct answer ... but I would have to say, yes.
The run caps may be in series with the start windings but they are still in parallel with the RUN's too. Even placing them outside of the motor and across the LINE of the motor windings would also lower the P. F. (as I had proven in another post). It just may not lower the P. F. as much. I do not know.
