Q:

How does a soft starter work?

A:

Full Answer

A soft starter gradually applies voltage and controls the supply going to the motor. There are two types of soft starters:

  • Open loop: also known as a time voltage ramp system, allows voltage to increase regardless of motor speed until the full supply levels are reached
  • Closed loop: starting voltage is modified according to motor speed or amount of current

By continually controlling voltage output, the soft starter improves the service life of any machine in which the starter is installed.

    How does a remote starter work?

    A:

    Car remote start systems use a coded pulse of radio signals to initiate a car's ignition sequence remotely when the remote starter's controller is activated.

  • Q:

    How do I know if my starter is bad?

    A:

    The first thing that indicates a possible bad starter is a car that does not start. If the car does not crank when the key is turned but makes a clicking sound, the lights need to be checked for dimness. If the lights are not dim, the starter is the likely problem. Another symptom is a slow crank that fails to start the engine.
