AVR Voltage Adjustment

Updated 1 month ago by Juan Velez

This covers the following Champion Power Equipment models: 196cc - 439cc Engine Powered Generators.

Read instructions carefully and completely before performing service.
SAFETY PRECAUTIONS

  • To reduce the risk of injury, user must read and understand the operator’s manual before using this product.
  • DO NOT make any adjustments to the generator without first stopping the engine and disconnecting the spark plug wire.
  • Burns from hot parts — let the engine cool completely before touching hot parts.
  • Injury from moving parts
  • To reduce the possibility of fire or explosion, be careful when working around gasoline. Keep cigarettes, sparks and flames away from all fuel‐related parts.
  1. On the end of the generator locate the round, yellow cover held on by two 7 mm bolts. Remove the bolts and the yellow cover will come right off.
  2. At approximately 7 o'clock, you will see a kidney-shaped electrical component called the AVR, which is held by another set of 7 mm bolts. Remove the bolts, but do not disconnect the wiring, and turn the AVR over so you can see the backside. You should be able to see a round piece coming off the AVR--this is the capacitor. You will also see a small rectangular box with a jewelers screw--this is your voltage adjustment screw.
  3. With a flat head screwdriver, turn the jeweler's screw counter-clockwise; this will lower the voltage. As the screw is turned back, watch the volt meter to see said adjustment; the generator must be running to do this.
  4. On a 5000W + unit, adjust the screw until the meter reads 250 volts. On smaller units the voltage should read 120 volts.
  5. If the voltage does not decrease or does not hold a steady output, please contact our technicians at 1-877-338-0999 for a new AVR.
