To test a single-phase motor, first remove the cover of the motor’s wire, and disconnect the wires. Test the lead using the volt-ohm tester followed by a capacitor. Protect yourself from electric shocks by wearing safety gear. Ensure you have a pair of gloves and safety glasses because the voltage o


While there are several tests for the starter on a vehicle, bench testing provides a definitive answer to a car that does not crank. However, before removing the starter from the vehicle, EasyAutoDiagnostics.com recommends eliminating other possible reasons for the car not cranking.


Single phase motors can be reversed by either swapping the starting winding or the running winding around but never both. When both windings are swapped around, the motor still runs in the same direction as it did before.


To replace a starter motor, locate the old starter in the vehicle, and disconnect the wires at the top of it. Unbolt the starter with a socket wrench, pull the old starter away, and place the new starter in the same position, reconnecting it to the wires and bolts.


The starter motor of a car works by engaging with a gear found on the flywheel of the engine to start the combustion process. A starter motor and a starter solenoid comprise the starting system of a car.


Three-phase motors are rotating electric machines powered from a three-phase source of alternating current. The motors have two main components: the stator and the rotor. A rotating magnetic field produced in the stator induces electromagnetic flux in the rotor. In turn, current in the rotor flows i


An electric starter motor works by generating a heavy electric current at high speeds to turn and start an engine. The starter motor is equipped with a large electric switch that turns on and then off automatically in a short period of time. The electric switch is made to withstand high currents fro


Visually inspect the motor for damage, and if there is a manual thermal switch, reset it. Check for voltage at the motor terminals, and troubleshoot the circuits leading to the motor. Inspect the centrifugal switch for damage, and test it with an ohmmeter.


Wiring a three-phase motor begins with turning off the circuit that supplies power to the motor. Open the motor wiring box, and check for a nameplate with the wiring information. Connect all of the wiring with the right size, and number that coordinate with the conductors you want to use. You can ei


A three-phase motor should be wired with the positive and negative ends connecting to the corresponding power sources. The motor wires generally do not have symbols or colors that indicate the positivity or negativity of the wires, so the motor should be tested in a controlled environment before it
