A start capacitor is wired in series with the motor's start winding via a centrifugal start switch. The switch disconnects the capacitor and start winding once the motor has reached a pre-determined minimum speed. The motor then continues to run on its main field winding.
A different design uses a "start-and-run" capacitor which remains in circuit whilst the motor is running.
Connect your start capacitor in series with the start winding.Connect the run capacitor in the common terminal and Line 1 of the power supply.
To wire a compressor capacitor and a fan capacitor, first ensure that the power supply is turned off for safety. Connect the compressor capacitor by connecting its common terminal to the compressor, the herm terminal to the power supply, and the start terminal to the start winding of the compressor. For the fan capacitor, connect its common terminal to the fan motor, the fan terminal to the power supply, and the start terminal to the start winding of the fan motor. Always refer to the wiring diagram specific to your unit to ensure correct connections.

You can not by-pass the capacitor in an electric motor. Most are capacitor-start motors which require the capacitor to be operational in order to start. If the capacitor is not working then it will need to be replaced.
No. You won't be able to start the motor without the capacitor.
To determine positive and negative connections on a motor start capacitor, first check the capacitor for markings; many have a "+" sign indicating the positive terminal and a "-" for the negative. If no markings are present, refer to the motor's wiring diagram or specifications. Additionally, use a multimeter to test continuity, ensuring the capacitor is discharged before making any connections. It's essential to connect the capacitor properly to avoid damage to the motor or capacitor.
This is for a single voltage motor. If you consider the forward rotation as counter clockwise (CCW) when looking at the motor from the end opposite the drive end, then the connections will be, L1 - terminals 1 and 8, L2 - terminals 4 and 5. To reverse the rotation (CW), then the connections will be, L1 - terminals 1 and 5, L2 - 4 and 8.
A capacitor start motor is a split phase motor that uses a capacitor in series with the start winding to cause a greater phase shift, resulting in greater starting torque. It uses a centrifugal switch to switch out the start winding and capacitor once the motor is up to speed. I assume this switch is what you're referring to as a "relay".

To wire a Dayton 1 horsepower electric motor with a capacitor, first ensure the power is off and the motor is disconnected from the electrical supply. Identify the capacitor terminals and the motor's wiring diagram, typically found on the motor's nameplate. Connect the capacitor's positive terminal to the motor's start winding and the negative terminal to the common terminal; then connect the run winding to the common terminal as well. Finally, connect the power supply leads to the appropriate terminals, ensuring all connections are secure and insulated before turning the power back on.
I have never come across a three phase capacitor start motor. Any three phase motors I have worked on are induction start.
A pool motor capacitor helps start and run the pool motor by storing and releasing electrical energy. It provides the necessary power boost to start the motor and helps maintain a consistent speed during operation. Without the capacitor, the pool motor may struggle to start or run efficiently.
