Checking Pool Pump Electric Timer Circuit Wiring
[ad#block]Electrical Question: I have a Pool pump that is not working. I took voltage readings at the breaker and both hot legs read 124 volts.Then I took readings at the timer where one leg 124 volts other leg 35 volts. I suspect water or moisture in the conduit from the breaker panel to pool timer. It is an underground conduit.

This electrical question came from: Walt, a Handyman from Phoenix, Arizona.

Electrical Tips to Help You Wire it Right

The Safest Way to Test Electrical Devices and Identify Electric Wires!

The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.

The Quickest Way to Check for Faulty Electrical Wiring!

The Plug-In Outlet Tester
This is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect Very handy and easy to use.

Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!

The Wire Stripper and Wire Cutter
My absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires.
This handy tool has multiple uses:
The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets..

The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use.

    My pool pump does not start. I checked the power and have it going into the pump. Is there a relay I need to check? Thanks and please send a picture of what I would look for.

  2. Dave Rongey says:

    Hi George,
    If the pool pump has power to the motor and the motor is not working then a capacitor may need to be replaced or the pump motor may be bad and need to be replaced. Turn the power to the pump off, wait a few minutes, then turn the power back on and see if the motor is trying to start, if it is but it does not come up to full speed then it is most likely the start capacitor that need to be replaced. Most electric motors are protected by a thermal cut out switch which protects the motor from over heating, and in such cases like this. The pump should be controlled by a time clock to schedule the operation of the pump.
    I hope this helps.
