Yup...likely a part winding start. Easy to hook up. Both starters have the line side connected to the same breaker. Most times, they wire to the first starter then jumper over to the second. As long as the phases are the same on the top side of the starter, they will be the same on the load side. To test rotation without a meter, just disconnect the motor leads from one or the other starter and give it a quick bump. Then do the same on the second starter. A quick bump on a part winding is not a problem. Just see that they both rotate in the desired direction. Motor leads are usually labeled with the first winding 1, 2, 3. Second may be 4, 5, 6 or 7, 8, 9. If in doubt about windings, do a continuity check between wires. Winding one will read low ohms between leads. Winding two will read the same. Winding one will not read to winding two. They're separate. If you have some other motor such as multi-voltage or star/delta, they are different. Be careful.
We have many pump stations with three of four pumps. One pet peeve of mine is finding someone reversing rotation at the starter. In my opinion, that's a headache. Phase sequence should be clockwise at the starter ABC, Brown Orange Yellow, left to right or top to bottom. Then, if you want reverse rotation at the motor, reverse the leads at the motor, not at the starter. Write the colors BOY or BYO inside the cover, so you'll always know. That way, any time you disconnect motor leads, you'll always know that it's Brown, Orange, Yellow Left to right. That's my opinion. If yours is different I'll loudly explain why you're wrong.
