SOURCE: I have a Coleman Vantage 3500 motor runs no generator output

This sound like a loss of residual magnetism in the generator. The field will need to be "flashed".This is also known as re-exciting the field of the generator.
The Coleman manual gives these steps:
1Use a 6 Volt lantern batters (dry cell) or a 12 Volt automotive battery.
2.Disconnect all loads from generator.
3. Remove the brush cover (that's the rectangular plastic cover on the end of the generator.)
4. Plug a lamp or light into the generator before starting the engine. The light will illuminlate when ?Voltage has returned.
5. Start the engine with no load connected to the generator.
6. Attach the "-" lead of the battery to the negative brush. Very briefly touch the "+" lead of the battery to the positive brush. Remove as soon as Voltage builds up.

SOURCE: no output voltage for powermate generator

NO. the capacitor resonates with a winding it is in parallel with as part of the voltage regulation.

Recharging a brushless generator can be tricky. I have had success using two 150 watt lamps in series between the running generator and the electric utility power. Search google for this method.

Check the voltage sent to the field when running. It will probably be around 12 volts. You can try connecting a lantern battery BRIEFLY to the field to re-magnetize the field. Try bothe polarites.

Some have had a bad rectifier and one had a bad transformer that generaates the low voltage from the generated output. He had a broken wire from the winding to the wire from the transformer. He was able to reconnect the failed solder joint.

Testimonial: "Thanks for info. I had it solved. I found the 130uf 200V rated cap was bad. 12 volts to the brushed did re-energize the field, power is operating. TY"

Well, its not exactly a published procedure, but this is what I would do.

Check field for continuity between leads, as well as continuity from each lead to the core. Between leads, you should have continuity, but you shouldn't be able to measure anything (perhaps in megohm range) between leads and core.

Once you have continuity, check your diode. You should have continuity in one direction only. If not, replace diode. Don't worry about capacitor / regulator at this moment.

Check stator winding for continuity between leads, (don't forget the 12 volt winding too), as well as between each lead and the core. You should not have continuity to the core from any lead.

Make sure breakers are reset, then check continuity through them. Should have it, replace if not. Same goes for the outlet itself.

Reassemble the engine, and start it. Check for a DC voltage at the 12volt battery charger port. If you have it, then your capacitor / regulator is shot. If you don't have it, replace the diode (even if checked good) and the capacitor / regulator. If still don't have 120vac, you can try to flash the field by momentarily touching a small lamp battery (6 volt lantern) to the core, and to one of the brushes. Just for a moment. Then restart. Exact flashing instructions are usually in the user manual.

Have fun!

Generator will run but no voltage output


Check the obvious, make sure the breaker is on, as this genset requires that breaker to be closed. Check to see if you have power on the generator / not laod side of the circuit breaker. If you do then the problem is the breaker, if not you need to dig deeper, and mesure the stator resisitance, most likely is the rotor excitation capacitor is open, this was common on those units, and will prevent excitation.

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.

The generator needs to be 'flashed' to bring back the excitation for output. Is this something you can do? Let me know and I can help you...
