Generator/Regulator Output Test

  1. Test system using a generator tester with carbon pile. Hook up tester according to manufacturer's instructions. Start engine and operate at 3000 RPM until radiator fan comes on, then let engine idle. Increase engine speed to 2000 RPM and hold. Observe voltmeter. If voltage is more than 15.1 volts, replace voltage regulator.
  2. If voltage is 15.1 volts or less, return engine to idle. Ensure all accessories are off. Connect inductive pick-up over generator terminal "B" (battery terminal wire). See Figure. Ensure arrow on inductive pick-up points away from generator.
  3. Increase engine speed to 2000 RPM and hold. Observe voltmeter. If voltage is 13.5 volts or more, go to next step. If voltage is less than 13.5 volts, test and repair generator components as necessary. Repeat voltage test.
  4. While observing ammeter, apply load with generator tester carbon pile until battery voltage drops to 12-13.5 volts. If less than 75 amps has been applied, go to next step. If 75 amps or more has been applied, charging system is functioning properly.
    CAUTION: Voltage will increase rapidly during full field test. DO NOT allow voltage to exceed 18 volts. Damage to electrical system may result.
  5. With engine speed still at 2000 RPM, full field generator. Insert test probe into full field access hole, located on back of generator. See Figure. If 75 amps or more exist, replace voltage regulator. If less than 75 amps exist, test and repair generator components. See BENCH TESTING .
