If you live in an area where there is a risk of power outages, you may already be aware of the specialty dealer in the generator you need to call. However, as you might realize, there is more to buying a generator than just the hardware itself because a generator needs to be maintained in order to ensure that it is ready when the power goes out.

This post will go over some of the basics of how to flash a generator field and how you can keep your generator in good shape.

A generator can be a lifesaver in an emergency, but only if it’s in good working order. Here’s how to flash a generator so that you’ll be prepared for when the next power outage happens.

How do Brushless Generators work?

A brushless generator is made up of an electric motor that turns inside the generator’s stationary magnetic field. One or more magnets are attached to the shaft of the rotating part, which then interacts with these stationary magnetic fields. The strength and polarity of the magnets determine the voltage produced by each coil, which in turn is sent through cables to the electrical appliances.

How do Brushless Generators work

The generator’s magnetic field is created by a bank of 12v/24v batteries and the direction in which the motor rotates determines the direction of current flow. The battery bank starts charging when it senses that more than half of its capacity has been used up and stops when it has reached an optimal voltage.

Flashing a brushless generator

Generators are designed to be user-friendly. If you have the necessary information it is very easy to do, but you must follow specific guidelines. A flashing session for a generator takes about 10 minutes and consists of the following steps:

  • Connect cables A, B, and C on the control box. Make sure they are connected in the right order before proceeding, as the cables are not interchangeable.
  • Turn on the generator and wait until it is in ‘standby mode.
  • Disconnect cable A from the control box for a few seconds and reconnect it again. The generator will start flashing automatically.
  • Follow the same procedure to flash a second time, with cable B instead of cable A.
  • Make sure all cables are correctly connected and turn on the generator.
  • You can now use your generator as you would normally do.”

To make a long story short, here’s how it works

  • Connect generator to BATT3 (-) and IGN (-). The control box will start flashing.
  • Disconnect BATT3 (-). The generator will run.
  • Disconnect IGN (-) and reconnect it within 5 minutes (the control box will start flashing again, then wait for it to stop before disconnecting the – terminal). The generator will not start running because there is no battery inserted.
  • After 5 minutes, reconnect IGN (-), and the generator will start running.

This is basically how the brushless generators work. The trick here is to disconnect BATT3(-) because a faulty battery can actually cause a short circuit and damage the control box if you simply remove it without making sure that all electrical connections are disconnected. This usually happens to the older generators which don’t have the built-in control box.

How to flash a generator?

When you need to start a generator, first check to see if it’s properly grounded. Next, open the fuel cap and check the fuel level. If it needs refueling, do so before continuing.

How to flash a generator

Then, locate the power switch on the generator and turn it on. Then, set the engine speed by turning the recoil starter handle until you feel resistance. Finally, hold down the choke lever and pull the starter cord until you feel resistance. Once the engine has started, release the choke lever.

You can flash a generator in the following way

  • Disconnect the negative terminal from the control box. The control box will start flashing.
  • Wait for the flashing light to stop, reconnect the negative terminal, and a flashing light will appear.
  • The generator will start running once you connect it to battery terminals A and B.

How to flash a generator with a battery?

Before attempting to flash a generator, you should always check that it is grounded properly. Next, open the fuel cap and add fuel if required. Once you have completed these tasks, find the power switch on your generator and turn it on. Set the engine speed by turning the recoil starter handle until you feel resistance and pulling in excess cord until resistance is felt.

Finally, pull on the starter cord to start the engine while holding down the choke lever. If you need to flash a generator with a battery, make sure it’s properly connected and turn the power switch on whilst pulling in excess cord until resistance is felt.

Release the choke lever when necessary. Set the machine to idle when you’ve successfully started your generator by moving the throttle control lever.

Flashing a generator with a drill

To flash a generator with a drill, you’ll need to use the following steps: Connect your battery charger or drill to one of its terminals, and do not connect it to the other terminal at this stage.

Disconnect cable A from the control box and wait until it stops flashing. Connect cable A, disconnect cable B for a few seconds, and reconnect it again. The generator will start flashing automatically.

Connect your battery charger or drill to the other terminal and wait for a few seconds. Make sure it starts flashing again, then connect both cables A and B together. Open the fuel cap and add fuel if required before you attempt to start up the generator.

How to flash a generator with an alternator?

There are 2 ways in which you can flash a generator with an alternator:

Connect the battery charger or drill to one of the terminals, then disconnect another cable that is connected to a different terminal for a few seconds. Reconnect both cables, and the generator will start flashing. This should take place automatically. Connect your battery charger or drill to another terminal and wait for a few seconds before disconnecting one of the cables and reconnecting it a few seconds later.

The next step is to set your RPM level to idle by moving the throttle control lever. Contact your local electrician if you need professional help with flashing a generator.

How do you flash a portable generator?

Portable generators can be a great tool to have in an emergency, but it’s essential to know how to use them safely. Here are the basic steps for safely flashing a portable generator:

How do you flash a portable generator

  • Make sure the generator is turned off and unplugged from any power sources.
  • Remove the cover of the generator.
  • Locate the spark plug wire and remove it from the spark plug.
  • Insert a metal object such as a screwdriver into the spark plug opening and hold it there while you turn on the generator.
  • Turn off the generator and replace the spark plug wire on the spark plug.
  • Replace the cover of the generator.
  • Re-plug the generator into

How to flash a generator field?

First, check the generator’s owner’s manual to see if there is a specific procedure for your model. If there isn’t a specific procedure, follow these general steps:

  • Make sure the generator is off and cool.
  • Remove the filler caps from the top of the generator.
  • Locate the field terminal block. It will be near where the power cord enters the generator. It will be a black box with three or four terminals on it on most models.
  • With a screwdriver or wrench, loosen the screws or bolts that hold the field wire connector in place.
  • Remove the connector from the field terminal block.
  • Attach one end of a length of heavy

How to flash a generator – FAQs

What is a brushless generator?
A brushless generator does not have carbon brushes, which can wear down and require replacement. The absence of these means that the electric motor is better protected against damage from stones or sharp objects. It also generates less heat when in use, has lower vibration levels, and reduces noise production.
What does it mean to flash a generator?
A generator is a device that converts mechanical energy to electrical energy. When you flash a generator, it means that the motor inside is running for a short time with no load on it. This allows for the quick starting of larger engines or machines without putting too much stress on the engine and its components. It also helps prevent damage due to overheating during starts when using high-volume gasoline engines with “throttle-body” carburetors
How do you Re-magnetize an electric generator?
There are a few ways to re-magnetize an electric generator. One way is to use a strong permanent magnet to create a magnetic field around the generator. Another way is to use an electromagnet. Another option is to use an alternating current (AC) source to create a rotating magnetic field around the generator. Finally, you can also use the generator’s own rotor magnets to create a rotating magnetic field.
