Leading cause of capacitor malfunction is not enough air in bladder tank , causing the pump to start - stop too much , overheats / blows the start capacitor in control box .
Make sure to check the air in bladder tank , .
What pressure?

bladder tank should have an internal pressure thats just below your pump start setting. if you run a 30/50 switch you want the tank pressure a bit below 30 psi

The voltages appear to be correct for single phase 240 3 wire. two hot wires and one common. either of your two hot wires to the common will give 120 and the hot to hot will give 240. I would try the pump control box first.

In post 6, Ken says he was testing the voltages to ground, or well casing. That why I suggested three phase, with one of the wires 240 volts.


But then he added that this is in bush town Aniak Alaska. So could they have different power up there vs continental US.

First off there is 3 phase pumps for residential. It's just uses a fancy VFD box to convert power to them. In fact lifetime warranty on the pumps. and available in lower horsepower setups too.

Here is what I found.
It is a 220vac 1ph pump.
There are 2 110 hot wires 1 ground and the 4th wire is a starter form the capacitor. Due to a malfunction in the control box, the starter wirer was sending
a constant 220.
I replaced the pump and control and life is good.

Did you check the air pressure in the bladder tank , with water drained and system drained ?
