That's what's confusing to me. Since there is no relay in the control box, it must be built into the motor?

Then either way, there is momentary voltage through the capacitor leg and then when it's up to speed, there should be none and switches back over to hot to run?

Yeah, different way to design a system. Less starting torque I would think.

See http://www.allaboutcircuits.com/textbook/alternating-current/chpt-13/single-phase-induction-motors/ "Permanent-split capacitor induction motor."

One thing you may be able to try, Is to disconnect that cap after the motor starts, If it is really starting.

If that works you can add a start relay, Or just add a momentary start button that puts the cap in circuit.

I may use that second switch box as a capacitor disconnect and play with it. That's besides bypassing the control box altogether to see if I can eliminate the voltage drop. But its rain for the next few days.

Bypass the box with the capacitor altogether? You will need a capacitor if that motor is to ever run.

I really think it does need a cap.

I would not try to do that.

Find out where your voltage drop is and fix that first.

The cap needs to be there for that type of motor. As Reach4 provided a good link for. (Or close)

I thought I was a little bit smart, but I can't figure out a word of what the hell is being discussed here.

If you want some Chinese crap pump to run with a chinese crap genset, try the tuhorse pumps that at least seem to be a good build. Or get a helical grundfos and run it with solar panels. Otherwise this all fairly ridiculous

I think it's a interesting read because voltage can do some crazy stuff, not getting enough to the motor, will defiantly not make the motor run, so where is the voltage drop coming from. Carry on, I am interested in finding out what it is.
