Fitment Guide

  • RV motorhomes
  • Recreational vehicles and camper systems
  • Mobile service vehicles
  • Emergency/backup power units
  • Industrial generator applications


An alternator stator is the stationary (non-rotating) part inside an alternator or generator that produces electrical power. It works together with the rotating part (the rotor) to generate electricity.

 
  • Produces electricity
    • The stator contains copper windings that generate AC electrical current when the rotor's magnetic field spins inside it.
  • Supplies power to electrical systems
    • Provides electricity for vehicle, generator, or equipment systems such as lights, controls, sensors, and accessories.
  • Charges batteries
    • In vehicle alternators, the stator produces the electrical output that is converted and regulated to recharge the battery.
  • Provides stable generator output
    • In systems like Cummins Onan generators, the stator is a key component that creates the power delivered to appliances, tools, and electrical equipment.
  • Supports continuous operation
    • A properly functioning stator allows the alternator or generator to produce reliable power during extended use.

Signs of Faulty

 
  • Low or no electrical output
    • The alternator/generator runs, but voltage output is weak or completely missing.
  • Battery not charging (vehicle applications)
    • The battery becomes discharged because the alternator is not producing enough power.
  • Unstable voltage output
    • Electrical power fluctuates, lights may dim, or equipment may shut down unexpectedly.
  • Generator produces no power
    • On a Cummins Onan generator, the engine may run normally but connected devices receive no electricity.
  • Burning smell
    • Overheated or damaged stator windings can produce a burnt electrical smell.
  • Overheating
    • The stator may become excessively hot due to shorted windings or insulation failure.
  • Discolored or damaged windings
    • Burn marks, melted insulation, or darkened copper coils are signs of overheating.
  • Circuit breakers trip
    • A damaged stator can cause electrical shorts or abnormal current flow.
  • Strange electrical readings
    • Voltage or resistance tests may show the stator windings are outside specifications.
