I HAVE AN OLDER POWERMATE COLEMAN 5KW. NO ELECTRIC OUTPUT

I HAVE AN OLDER POWERMATE COLEMAN 5KW. WAS NOT PRODUCING ANY ELECT. CKD THE ROTOR WAS OPEN, ORDERED AND INSTALLED NEW ONE. CKS BRUSHES, DIODES, AND CAPACITOR GOOD. STARTED UNIT AND MY VOLTMETER READS 135V. AT RECEP. BUT WHEN I PLUG IN A LOAD NOTHING HAPPENS. ANY IDEAS. DO I NEE3D TO FLASH AND HOW DO YOU DO THIS? WHAT SHOULD I READ ON VOLTMETER AT THE BRUSHES WITH MOTOR RUNNING?

    THE MODEL IS A PM0545212.02 ALSO, THE VOLTAGE DOES NOT DROP WHEN I PLUG IN A LOAD, JUST WONT OPERATE LOAD. ALSO TO I NEED TO FLASH THE NEW ROTOR. THE STATOR HAS 7 LEADS, 2 WHITE, 2 BLACK, 2 RED, ONE BLUE, HOW DO I CHECK THE WINDINGS IF THIS IS THE PROBLEM. SOMEONE ADDED NOTE OF 75 VOLTS DC. IS THIS THE VOLTAGE I SHOULD READ ACROSS THE BRUSH TERMINALS?

    the model is a pm0545212.02 it is 5 kw 10hp. i check the voltage at the plugs from neutral to line with volt meter check one plug while load is plugged in. check line to ground and no reading. tried various loads, lights and tools

    This is curious, you say you have 135 volts. That's what we call 'no load voltage'. What is happening is as soon as you put load on it it drops to zero. What that is, is a bad connection dropping the voltage down. Check all the connections on the recepticle and on in to the stator output. You will see it.

    Please tell me how you are testing the voltage? With a load plugged in, do you have 135 volts in the plugs? Are you checking to ground, or right between the hot and neutral, in the plug? I can tell you how to flash if we need to, give me the model number if yo know it.
    If you have 135 volts between the hot and neutral, in the plugs, that should run it. Have you tried some other power tool or just the one?

    I will send flash instructions, to flash field

    To flash field:
    Using a 6 or 12 volt battery, connect + lead from battery to top right brush. Negative to other brush. With gen running touch leads to brushes for 2-3 seconds. May need two or three attempts. Recheck voltage output. If still no output, may need to check capacitor 9 (behind end cover) for open or shorted condition.

    Did you flash the field? I did not hear back...??

Have a coleman powermate 6750 generator that has quit producing power.


If the engine is running with the alternator not outputting then you must check with the LOAD TRIP switch.
if not remove the load and check if there is output. If not there is fault in tha alternator which might need some consensus.

How to flash or remagnitize Coleman Powermate 6875 or Husky 40500


Field Flashing of Portable Generators This tip comes from the Briggs & Stratton Customer Education Department. As an alternative to flashing a rotor winding with a battery applied to the brushes, an electric drill may be used. Follow these steps to flash the generator:
  • Plug the electric drill into the generator receptacle. (Cordless drills do not work)
  • If the drill is reversible, move the direction switch to the forward position.
  • Start the generator
  • While depressing the trigger on the drill, spin the drill chuck in reverse direction. This will excite the field and the generator will now produce electricity. If spinning the chuck one direction does not work, try spinning the chuck in the other direction as you may have the reverse switch positioned backwards.
Use caution not to get your hand or other materials caught in the chuck. As soon as the field is excited, the generator will produce power and the drill will turn on.
The reason this works is because the electric motor in the drill will act as a small generator when spun backwards. The magnets in the drill's motor induce a voltage into the motor windings, which is fed back through the trigger, cord and into the generators receptacle. From there it goes into the power winding of the stator. The voltage going through the power winding creates a magnetic field, which is intensified due to the iron core of the stator laminations. The rotor intersects this magnetic field as it is spun past the power winding, thus inducing a voltage in the rotor winding. Once current flow is present in the rotor winding the rotor has been flashed.
If flashing the field does not make the generator work, you may have additional problems, besides a lack of magnetism in the rotor. Further testing will be needed. Hopefully, this will give a simple way to field flash your generator if needed - Bruce Perrault

No AC out put


After working on several of this style coleman generator,i have found that the lead wires in the windings that are soldered to where your brushes would contact tend to break.I don't know if it's a poor design or just a fluke,i would check to see if your getting continuity on the rotor and go from there.They seem to either "burn off" or just break.

I would say, yes (given everything bolts up okay), but I wouldn't connect a full 5000-watt load to it.

Coleman 5KW gen motor shuts down when A/C switch turned on


Sounds like a problem with the wiring of the outlets after the circuit breaksr. Take apart the outlet box and have a look for burned or broken wires, melted outlets, and/or small critters stuck in the wiring.
I recently had to repair a generator that had its voltage regulator taken out by a frog!

I have a coleman 5000 that runs fine but it stops producing power after it runs for a couple of minutes.


Same answer as the last time you asked, likely a flying open. If the rotor test proves that your rotor isn't opening up, test the capacitor on brushless models or the voltage regulator board on brush generators.

Generator will not produce electric power


Hi there,
Check the air cleaner to make sure that it isn't clogged with oil. If you find any significant amount of oil you may also need to clean the carb. Also check the spark plugs for fouling. Once you're convinced that the engine has no service related issues, check the governed throttle setting. To do this find the spring that pulls on the governor arm and look for either a tab to bend up or a threaded rod to tighten at the end of the spring not connected to the governor arm.

Carl

Powermate 5000


20kw means 20 KILOwatts (kilo=1000), so 20kw=20,000 watts
So the Powermate 5000 refers to wattage. 5000=5kw
