Sparkync,
I usually test for ampere draw at the wires at the well cap. Most of the 2-wire, 3/4 HP submersible pumps around here draw about 9 to11 Amps at 220 to 240V.
There is usually a tag or decal on or near the well cap with pump motor specs. Sometimes it’s at the circuit panel or at the controller if there is one.
Some brands of two-wire pumps also use a controller. If it has one I would check out the capacitor in it. Sometimes they go bad.
If you have the correct voltage at the well head then the pump is going to have to be pulled.
Are you going to pull the pump yourself?
If it’s less than 100 feet and connected with black plastic CPVC pipe, it shouldn’t be to hard to raise it. If it’s deeper or hard piped, you will need some help to raise and dissemble the pipe sections and then for reassembly
