Question about Coleman Powermate Powermate 5000W Generator
We bought a reconditioned Coleman Powermate 6875 November 2009.
We made sure that it started for a minute, then stored it until April 2010.
Now it has no output and will not even run a drill.
Does it need to be re-magnatized or flashed?
If so, how would that be done?
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:
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
