How to flash the field on Honda Generators.
After a stator rewind, it is usually necessary to flash the generator's field. This establishes the residual magnetism in the rotor. Shown
here is the method we recommend to do this. There are other methods that work, but we have chosen this because it has the lowest risk of
damaging the generator.
Caution: Use caution when flashing the field. Dangerous voltages are present that can shock or kill. Make all connections prior to
starting the generator and stop the generator before unhooking the connections. Electrical work should only be done by a qualified individual.
Always refer to a genuine Honda service manual for assistance.
- Disconnect the Automatic Voltage Regulator from the generator. This ensures that it won't be damaged during the flashing process.
- Unhook the main wiring harness from the generator head terminal strip. This ensures that the control panel won't be damaged during the flashing process.
- Connect the 9-volt battery to the brush terminals as shown above. Make sure the positive from the battery goes to the positive
terminal on the brush holder and the negative from the battery to the negative on the brush holder.
- Make sure the low idle switch is turned off. Start the engine and let it run for five to ten seconds. A volt meter can be used on winding one or winding two to prove the field was
flashed properly. The voltage displayed will vary by model, but will be approximately 65 volts.
- Turn off engine and unhook battery.
- Reinstall voltage regulator and main wiring harness.
- Start generator and check for proper voltage.
