Conduct Electrical Checks

What happens here

With the control box open (and ensuring power is safely disconnected if making direct contact with wires), use your multimeter, specifically its clamp meter function as shown in the video, to check for electrical continuity and current. First, verify voltage at the main power lines entering the control box to ensure there's power from the source. Then, check the output from the timer to see if it's sending power. Finally, use the clamp meter to measure the amperage drawn by the pump motor while it's attempting to run (if applicable and safe). The video shows the electrician checking these points and noting the motor readings.

Goal: Verify that power is correctly supplied to the pool pump motor and assess current draw.
