metal drop pipe, or an extra wire extending
into the ground water.
5. Readings and Conditions, motor installed in well:
a. 2,000,000 ohms or more - insulation
completely acceptable.
b. 500,000 to 2,000,000 ohms - insulation
in reasonably good condition. Acceptable.
Should be considered marginal for new motor.
c. 20,000 to 500,000 ohms - insulation seriously
damaged, but motor may still operate.
d. Less than 20,000 ohms - severe insulation
damage. Motor probably not operable.
WINDING RESISTANCE
Winding resistance tests indicate whether or
not windings are internally correct, shorted, or
open. Winding resistance should be considered
independently of insulation resistance readings.
1. Set ohmmeter to RX1. Short meter leads
together and adjust indicator to zero.
2. Be sure power is turned off.
3. Connect ohmmeter between two motor leads.
a. Three wire single phase: Yellow-Black
indicates main winding resistance; Yellow-Red
indicates start winding resistance.
b. Three phase: Resistance values should be
equal on all three phases: Yellow-Black;
Yellow-Red; Black-Red.
4. Correct readings should be equal to the Line-to-
Line resistance values from the specifications
section for a given motor, plus the resistance of the
drop cable from the table below.
5. Conditions:
Resistance (Ohms) Per 100 Feet of Copper Cable
(Round Trip)
AWG 14 12 10 8 6 4 2 0
Ohms .5 .3 .2 .12 .08 .05 .03 .02
a. If one ohm value is less than specified, that
winding is shorted.
b. If one ohm value is greater than specified, that
winding is open, or there is a poor connection
in that circuit.
c. On 3-wire single phase, if one ohm value is
greater than specified and one ohm value is
less than specified, the leads are mixed. See
the section entitled “Cable Identification When
Color Code Is Lost.”
TESTING LOAD CURRENT AMPS
To test load current amps a clamp-on ammeter is
required. Since the ammeter measures current flow,
the motor must be running.
1. Pull the motor lead wire, being measured, (red,
yellow or black) away from all other wires.
2. Set ammeter to the highest scale. (If starting
a motor leave on the scale until current settles
down).
3. Place tongs of meter around wire.
4. Change meter scale to one that gives the best
accuracy. This will be a reading between mid
scale and full scale.
5. Compare reading with current load amps on
motors data chart.
6. Test each motor lead.
