I might have tried that if I didn't already have it torn
partway down for
diagnostic purposes - I was looking for a loose connection or a
wire
unplugged . Not really a big deal on this model though , 4 screws
for the
end cap and 2 that secure the brush holder/rectifier unit .


My standard flashing kit doesn't require any disassembly. IT
consists
of a Jesus cord (male 120 volt plug on one end, flying leads on
the
other) connected in series with a 300 watt incandescent lamp to a
small AGM 12 volt battery.


Cranking the chuck of a corded electric drill plugged into the
generator
by hand to energize the field coil may be more convenient.


To use, crank the generator and then simply stick the Jesus cord
plug
into one of the outlets for just a moment. The lamp when cold,
allows
quite a bit of DC current to flow. That almost instantly
energizes
the field which makes the generator start generating 120 volts.
That's
when the lamp lights, protecting the battery from an AC surge.

I used to have one generator that required flashing almost every
time
I used it. I solved that problem by drilling the edge of the face
of
one stator pole and gluing a tiny super-magnet in the hole.
Problem
solved for as long as I owned the unit.


This is ingenious. There will always be "residual" magnetism in the
poles.


Yea, after the power is off. Then, its like a capacitative effect, but
it could be dangerous if you take it apart (if it isn't first bled).
You know, it could "whack" you a bit.

Electricity and magnetism behave differently from that under our
yellow sun.
