The alternator helps maintain the voltage of the 2014 Jeep Patriot battery. There are four main components of an alternator . The stator and rotor are belt-driven magnets encased in copper wiring. They create a magnetic field. The belt is driven by a pulley that connects to the engine. This spins the rotor and creates a magnetic field. The stator uses this to create voltage and electricity which flows to the diode. The diode assembly than converts the AC electricity to DC, which is used by the 2014 Jeep Patriot battery. Finally, the voltage regulator acts as a surge protector for the alternator. Where Can I Find Second Hand Alternators for Sale?

Jeep Patriot Bad Alternator Diagnosis

Some alternators go bad right away, and some slowly lose their ability to charge under heavy loads. The ones that fail completely are easy to diagnose. The battery drains and you are stuck with a vehicle that goes nowhere.

The challenge is diagnosing an alternator that is just not quite charging like it needs to be. You can easily diagnose it with almost any multimeter. Heres what to do.

  • Get a multimeter. They are cheap , and you can get them almost anywhere.
  • Set it to read voltage. Specifically, youll need to set it to 20V DC.
  • With your Patriot turned off, youll connect the negative side of the meter to the negative battery post or wire. Youll then touch the positive side of the voltmeter to the positive battery wire. With the engine off, you should get a reading somewhere between 12.0 volts and 12.6 volts.
  • Now that you have this baseline, its time to turn the engine on. Lets go ahead and leave the air conditioner off, as well as the headlights and any other accessories.
  • With the engine just fired up, you should get over 14.2 volts. If you got 14.2 or more volts, the alternator is charging fine. If its still showing in the 12s, its time to replace the alternator. If its producing a voltage level in the 13s, go ahead and take it into a parts store and have it tested. Its probably bad.
  • This test depends a lot on you to notice very subtle differences in lighting. It should not be used in substitute for checking the voltage as described directly above.

    How To Test The Alternator

    The easiest method to check the alternator is by measuring the voltage at the battery terminals when the engine is running.

  • Start your Patriot.
  • Connect the black cable of the multimeter to negative terminal of the battery, and the red cable to the positive terminal.
  • The voltage should be between 13.5 and 14.8 volts with the engine running.
  • Switch on the accessories in your Patriot, for example, headlights, AC fan at full speed, and interior lights.
  • The voltage should remain around 14 volts. If it drops and remain below 13.5 volts, it indicates a problem with the current supply from the alternator.
  • If the voltage drops below 12 volts with the engine running and the accessories turned on, it means the current supply from the alternator is completely cut off and all the electronics are solely powered by the battery.

    Slipping Serpentine Belt Can Cause Bad Alternator Symptoms

    The serpentine belt, also known as accessory belt or drive belt, transfers the power from the engine to other components like the alternator and the AC compressor, that are essential for normal operation of your Jeep Patriot.


    If the serpentine belt is damaged or becomes loose, or if the alternator pulley develops a defect, it can cause the belt to slip. This can cause the alternator to spin slower or inconsistently and the electricity production is degraded. When the on-board diagnostic system detects low voltage from the alternator, the battery symbol light comes on in the instrument cluster of Patriot.
