Two problems affect cable integrity, shorted lines and broken or open lines. the following porcedures will determine cable integrity, The cable should

be disconnected from both the motor and the control panel. Verify the power is off before removing the cable.

1. Set up the multimeter

a. Set the multimeter to the lowest Ohm (resistance) setting. Resistance is designated by Ohms.

b. Determine how your multimeter designates open line. This is done by observing the reading when both probes are held in the

air, not touching.

c. Determine how your multimeter designates continuity. This is done by touching the two probes. This should be either zero or

very close to zero. If not zero, this may be resistance internal to the meter and should be subtracted from all subsequent readings.

2. Disconnect the cable from the control panel and the load (pump or lights). Both ends must be dry. Verify the power is off before removing the

cable.

3. Check for shorted lines. A short is an unintentional electrical path and can be caused by faulty insulation.

a. Set the multimeter to the highest Ohm (resistance) setting.

b. Take readings by touching the probes to each pair of wires; e.g. red-black, red-yellow, black-yellow, etc.

c. Analyze the readings.

i. The readings should be the same as the open line readings you observed in step 1b.

ii. If the readings designate continuity by giving a zero reading or any reading less than open line, a short exists.

iii. If any of the readings with green (ground) indicate continuity, a leak to ground exists.

d. Determine the action to take

i. Visually inspect the cable.

ii. Any manual connection sites are candidates for inspection, e.g. junction boxes, splices.

iii. It may be impossible to determine the location of the short and a new cable may be the best solution.

4. Check for open lines. An open line is a break in a wire.

a. Set the multimeter to the lowest Ohm (resistance) setting.

b. At the control panel, with the cable disconnected from the control panel, join two wires, e.g. red and yellow, by wrapping the

ends together. If you have four wires, you may wish to connect the other two together. Note which wires are connected.

c. From the other end of the cable select one of the pairs of joined wires and take reading by touching the probes to each wire

or socket of the connector.

d. Analyze the readings.

i. The readings should indicate continuity, (either zero or close to zero). The readings should not exceed a few

Ohms.

ii. If the readings indicate either open line or a very high number, a break or partial break exists.

iii. If a break exists, one or both of the wires tested may be involved.

iv. Determine the action to take.

e. Perform these steps for each combination of wire pairs.
