Yeah got to be something wrong with the motor. No load amps for submersibles are not published anywhere that I know of. You may can find out from the manufacturer. But no load amps on a 1HP should be about 3.5 to 4 amps. If 8.2 was no load motor amps, that would mean the pump could only add 1.6 amps, as service factor amps are only 9.8 for a 1HP motor/pump. So 8.2 for the motor alone is not right.

Run a motor without the pump (no load), a 3 wire is 8.0 amps and 2 wire is 8.2 amps on 1hp.

There is nothing wrong with the motor/motors. Our 1hp 3 wire test motor with stripped teeth that we use to test control boxes with tested at 8.25amps. It was either 8.4 or 8.6 on the 2 wire motor so guessed 8.6amps. I can retest the amps on the 2 wire when I make it back to the shop, if it makes you feel better.

I took a picture this time on our test motor.

Here is a picture of the 2 wire 1hp motor by itself

I don't know why your 1HP motors will only drop to 8 amps without a pump on them when my 1.5 HP drops from 11.4 to 6 amps and my 2HP drops from 12.8 to 6.6 with a pump attached. Maybe you could call Franklin and see if they will tell you what the no load amps for these motors should be. But 8 amps is too much for no load amperage on a pump that will draw 9.8 when the pump is attached.

I tried it on a brand spanking new motor as well. I did notice on the new motors and the 2015 Aim Manual, Franklin updated the 2wire to 10.4

I tested a 2 wire 1.5hp 25gpm Grundfos (Pictures 3-4) not a new motor test or pumps since I don't sell this brand.

I never use a 2 wire motor so I don't have any to test. But from your amp meter pics it looks like it dropped from 11.4 to 7.7 amps. That is pretty good but not nearly as much drop as I got with the 3 wire motor on that same 25 GPM type pump. The 3 wire 1.5HP I tested dropped to 6 amps. I didn't realize 2 wire motors used more amps than the 3 wire.

 

[PumpMd]

It was 11.4 to 8.59 amps. The 7.7 is what the brand new 1hp did by itself and on the 16S10-10.

On the 1.5hp, it was a 25S15-9

It's harder for me to find a 3wire, since I think we haven't used them from mid to late 70's. I will have to build one.

 

[Valveman]

I would not have thought a 2 wire motor would make that much difference. That was a 25S20-11 in the 2HP that dropped to 6.6 amps, and a 16S15-14 in a 1.5HP that dropped to 6 amps, but they are 3 wire with a control box. I can see where the run capacitor would help with power factor correction, but the 1HP and smaller do not have run caps.

This is what we use on top of the pump to go in the test pit. It was probably built in the 70's. I did check to make sure the valve was still shutting off 100%.
