[TheForge] Generators

[qualityrepairs at bellsouth.net]

The purpose of flashing the coil is not to restore residual magnetism, but only to excite the generator to produce current.  To rebuild residual, the machine needs to be run, preferable near full load, for a few hours.  Good maintenance would include doing so a couple tims a year.  I try to do that will all of my bigger rental units (20 kva and up) although the large ones are difficult to load near full.  That rebuilds residual.  Brushless generators do sometimes need to be flashed. Dropping generator or striking a field pole will destroy the magnetism in the steel core of any genset.  Magnetism is, afterall the alignmentof the charges in the steel, and a sudden impact will "scramble" that alignment.  I'm glad I've been able to take part in this discussion.  In the future I won't believe nearly all that I read.

The drill will make eniugh voltage to do the job, and the circuitry in the generator will put it where it needs to be.  But don't take my word for, just ask Briggs and Stratton.
