Hi!

We have a put together a guide here to assist you in these situations. It will guide you through testing and repairing the Generator. : https://www.generatorguru.com/need-help/

Check the circuit breakers for a tripped one. If all OK, then the brushes may need to be replaced. Here's a tip on how to flash the field in the generator: 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

I couldn't find parts for your drill, but if you call or e-mail the manufacturer hopefully they can help you.

Magnetic drills have a safety system built into them so the motor will not run unless the magnet is on and the tool is sitting on between at least 1/8-inch and 1/4-inch steel. If your drill is sitting on enough steel you may have a problem with the sensor system inside the drill. Those problems are usually electronic parts related and, most of the time, they are R&R (Remove & Replace) method is used until you fix the problem.

If I'm not mistaken, these drills use an electromagnet. Start by measuring the current when the magnet is switched on, but not the drill. If you don't have a current meter, just plug the drill plus an incandescent light into a long lightweight extension cord. You should see the light dim a little when you switch on the magnet. If the light doesn't dim, you just aren't getting power to the electromagnet, and it's probably a broken wire or a bad switch. If the tool has it's own fuse, I would think it would be for the drill only, not the electromagnet.

fist of all downlod the service munaul for laptop and remove the hdd and use the usb to sata & serial convertor cable and after .........use your destop and joint with convertor cable with hdd and insert cable in pc .....and backup all data ........after format the hdd .............ok 100% working my tips ..........noting rong in this help

hi first try the magnet on a clean flat piece of m/s sheet/plate 2 inches bigger than the magnetic base ,it should be very hard to remove make shure the magnetic base is clean and the beam you are drilling is paint and rust free if possible clean up the beam with a sanding disc try it make shure the cutter is sharp and use coolant a dull /blunt tool will need more force a good tool almost cuts with no effort on the handle if you are drilling upside down or on the side of the beam NOmagi drill will do this without extra support silk090
