How do i excite the generator on a miller airpac


Disconnect the rotor field wires at the AVR or on the exciter/brushes. Note they are polaroty sensitive. Connect a 12V battery to F+ and F- (note polarity) and momentarilly power from the battery for a few seconds. DO NOT forget to disconnect the rotor/exciter field wires first or the voltage regulator will be damaged.

Why doesnt my Homelite HG3500 generator not produce power when running?


Try flashing the rotor it has lost it's resideual magnetism through sitting.

Coleman powermate generator runs with no power


If we assume for the moment, that the internals of the generator are all ok. This problem is usually caused by not running the unit on load for a long time, a year for instance. During this time the residual magnetism in the field coils will slowly decay. When the unit is running the field coils control the power generated by the main windings. The higher the excitation voltage in the field coils, the higher the voltage generated by the main windings. The field coils are controlled by their magnets which, once a voltage has been generated, they will then self excite themselves.
However, if all of the magnetism has decayed then the field coils cannot generated because they have no excitation to start them off.
What you need to do is to find the field coil windings and while the unit is running with a load plugged in to it, you need to flash a voltage across the field coils.this will excite the field coils, part of that is used to do whats called self-excitation, honest...it is.
If you do this then a 12 volt car battery is a sensible thing to use for a power supply. But, as soon as the field coils start to self-excite then that voltage will increase far beyond 12 vo9lts. That is why you need a good size load connected, As the unit starts to generate then that load will alert you to remove the temporary supply, if you leave it connected the battery acid would rapidly boil and it can split the battery cases. That is why it's called 'flashing' it up. Once generating it wants leaving for a good hour,
If that does not produce results then the fault is deeper and requires testing by a qualified engineer.

My generator is only putting out 2.5 volts it is a powermate 5000 what is the most likely cause


Most likely the excitation DC circuit is broken or exciting rectifier (AVR if present) is damaged. If the field has been demagnetized it can be recharged by a 12 V battery, connected for a short time to +, - of the excitation winding, with engine running.

My generator turns on but, supply's no power?


You must check:
  1. Are your breakers ON?
  2. Measure the voltage on generator terminals.
  3. If the voltage is less than 20 V AC, you should check the excitation field, rings and brushes, AVR - rectifier, cables and fuses.
  4. If every thing is OK you may need to recharge the DC field with a short connection of "+" and "-" of a 12 V battery to respective field terminals when the engine is running.
  5. If the AC voltage raises for a second and drops when you disconnect the battery - the excitation circuit is bad.

Porter Cable Generator does not produce electricity


Here are a a few possibilities to look at:

1) Bad connection at the outlets themselves (loose wire) regarding neutral, hot wires.

2) Bad Excitation Capacitor. The Exc. Cap. is responsible for energizing the field wiring of the alternator. If the field is not energized, there will not be a magnetic field developed, therefore, no electrical output.

3) Open Field / Stator winding. If Field winding is open, no magnetic field will be developed. If Stator winding is open, no voltage will be induced.

4) Generator speed is too slow. If the RPMs of the engine are too slow, the output of the alternator will fail as well. Note that from normal speed, voltage output will occur but at reducing frequency until ouput ceases altogether, usually at about 47Hz. If your alternator is a 2 pole, engine speed should be 3600 rpm nominal. If alternator is a 4 pole (most aren't), engine speed would need to be about 1800 rpm nominal.

5) Generator speed too fast. If RPMs are too fast, output may fail as well. See above.

6) Excitation Fuse has blown. There is sometimes a fuse in the excitation circuit. To check this, you will likely need to pull the end housing off the alternator. Pay attention to bearings / bushings.

Generator starts but does not generate power


  1. Check for any blown fuse and replace. It can be traced directly from the output lines.
  2. Check field excitation. The field excitation is supplied by the battery to the excitation coil through a pair of carbon brushes. If the brushes are worn out, no excitation field is supplied and no output is generated. Replace carbon brush if found worn-out.
  3. Use an analog multitester to check the continuity of the carbon brush and the field coil.

Does anyone know how to repair Genset generators? I have tested the windings, the diodes and capasitor all seem ok. threis not an AVR. when i excite the capasitor the voltage comes up but won't stay, but...


You need to check the exciter circuit for the gen field. If there isn't a voltage regulator, there is going to be a circuit feeding the field. It could even be a 'permanent magnet' rotor inducing the voltage for the stator.

Do you excite generator while it is running ?


Yes! The generater must be running. Only apply voltage for one or two seconds when exciting then check for ac voltage with a meter. You can try again if no voltage. Note: if exciting the field does not work your problem may be something else.
