Question about Power Generators

1 Answer

Power Subbly I can't get new batteries for this drill. I need a 6 volt 1.5 or 2 amp power supply that I can put into the handle where the batteries were and run the drill as a cord drill off the 110v ac. If I had a schematic and parts list I could make it myself on a pc board. The drill had five cells in it so its a good size cavity approx 1 3/4 inch square.

Buy a small on board battery charger/maintainer its cheaper and they provide enough current and they do make them in 6 volt models

The engine is running but does not have power.


If the generator has been sitting for a long time or was shut off with the load connected it has likely lost the residual magnetism that is required to excite the winding. This is a common problem. Always disconnect the load from the generator before stopping the engine!

The generator needs to be flashed. There are several was to achieve this, but safest would be to use an electric drill.
  • Connect an older style portable 120 volt drill to the running generator.
  • Make sure the drill is in forward not reverse
  • With the switch depressed rotate by hand the chuck of the drill in reverse
  • careful, the generator will flash, power up and rotate the drill in the forward direction..
Hope this helps?

  • Careful the generator will flash the windings and power up the drill

Makita instructions


Get the battery tested. The light draws a very small amount of power and will work if the battery is just about dead, but to operate the drill, you need a strong battery.

This generator is a 5KW model. This means it can supply up to 5000 watts of power, total. Not all devices list the watts they need to be provided - instead these devices list the power they need as volts and amps. This can make it hard to determine what the actual watt requirements are for the device.

Overly simplified, watts is equal volts times amps (watts = volts x amps). A single 120 volt light bulb that uses .833 amps consumes 100 watts. If you checked a regular 100 watt light bulb with an ammeter, you'd find it does indeed draw .833 amps.

Working the formula a different way, we can learn how many amps this 5000 watt generator can supply at 120 volts, too. If all the loads you need to connect to this generator are 120 volt types, that means the total amount of amps the generator can supply is 5000 watts / 120 volts = 41 amps purely resistive loads (like a toaster or light bulb) maximum under ideal conditions. There is never a time when ideal actually happens, and not all loads are purely resistive - many are inductive. Inductive loads are motors (like your A/C), fluorescent lamps, computer power supplies, etc. - so figure more like around 30 amps total instead.

If you try to connect devices that require more than 30 - 35 amps, the generator will probably have problems trying to supply this load for any longer that a short length of time. Additionally, motors like those in A/C compressors draw significantly more power when first starting and can cause the problem you are describing. Try running the generator with loads other then the A/C to see how well it can supply the load(s). Or try running only 1 A/C unit and other non-A/C loads.

What I'm trying to tell you is that you may need to do some active load management to be sure that you aren't trying to get more power out of the generator than it is capable of supplying. You may need additional generators or swap this one to a larger size to handle the load properly and safely.

I hope this helps & good luck!

Generator does not output any power. Engine runs fine


I have the same problem and here is my troubleshooting steps I took.

1) Verified that the unit had no output with induction meter on cables coming out of top of generator head (three black and three white). You can use a volt meter too.
2) Checked that brushes were free and long enough.
3) Checked capacitor (condenser) was 130uF
4) Checked diodes

Powermate model 544000 generator undervoltage


There are basically 2 possibilities that can cause this.

1) Enigne RPMs are too low. but, since you already played with the throttle, this probably isn't the case. RPMs should be about 3600 though.

2) The voltage regulator / capacitor has high ESR (resistance) or is bad altogether. Replace.

My craftsman generator model # 580.32672 starts but will not put out any power ive tried a few suggestions but nothing has worked


Look in the manual. There is likely something about field flashing the magnetic field. According to the Briggs and Straton web site, the easiest way to do this is to.
1) start the generator
2) plug an electric drill into the generator (without drill bit)
3) make sure drill is set to forward direction (if a reversable drill.
4) pull the trigger on the drill.
5) If the drill does not start, spin the drill's chuck clockwise (When looking down at the chuck from the drill bit end). Spin counter-clockwise if holding it like a pistol and pointing away from yourself.
6) Do this several times (hard) until the the generator will kick in and suddenly make the drill spin at full speed.
Be careful not to drop the drill or poke someone with it as you celebrate success.

Honda Em6500 generator won't generate. Did the plug a drill into it and spin the drill chuck by hand. Started working but when i started it up recently, same problem and drill trick won't work. How do I...


You need to locate the the brushes and check to be sure the brushes are good. Then use a 6 or 12 volt battery to the proper pole on the brushes just for a few seconds. NOTE this can be Dangerous as you are using electricity and you have moving parts near where you will be working. Then try to see if it works Your winding may be shorted or open.

I plug a 1/2hp drill and use it I notice if I use anything else it is low of power. I put a meter on one plug and drill on other, and it reads upper 80-95 volts with drill running


Please check the owners manual.and see if the 6250W is surge power or steady state...it is not unusual..for this to occur...possibly the generator needs to be adjusted ( sped up slightly )..do not let the 120 volts output exceed 126 volts...

Brushless powermate (Black Max) Brand New Unit but never put out power


I looked at your parts blow up and noticed that you generator has a brush pack and a voltage regulator. Here are a couple of tips that may help you determine which part is at fault. Obtain a 12 - 16 volt ac power supply of about 1 amp and same voltage DC power supply. I find these at a thrift store and are used to power phones or door bell etc usually about 2 to 3 dollars each. This size power supply is relatively harmless and will not shock you or damage your generator. Remove the brush pack and set aside. You are going to apply 12-16v AC voltage into the 115v plug of your generator. You should hear a very slight hum in the stator if the winding is not open or shorted. Assuming that the 115v winding is ok, there should be voltage at the commutator rings and the armature should actually be making a magnet force. You can turn the armature slightly and actually vary the voltage at the rings. If you are getting voltage at the rings then winding and armature are progably ok. Remove the AC power supply and replace the brush pack. Next use the 12-16v DC 1 amp power supply (paying attention to polarity) to replace the voltage regulator. Disconnect the voltage regulator from the brushes and use the DC power supply to power the armature thru the brush pack and start the engine. You should get some low voltage at the 115v outlet and more important some ac voltage at the leads that power the voltage regulator. If no output at the leads to regulator then winding is open or short, if ac is present then regulator is most likely fault. Good luck, hope this helps, enjoy.
