I'm expecting cries of "bin it" but it's worth a try.

The output from this generator is low to non-existent. If I plug a
500 watt drill in, it might turn
sometimes, but only between probably 10rpm and 200rpm, it's very
erratic - guessing the speeds of
course - then it will stop altogether, and then maybe start up
again, slowly.

There doesn't seem to be much that can be done with these other than
maybe change the capacitor, but
my electrical knowledge is too lacking in such matters to even know
if that could be the problem.
Hi,

Try a google on 'generator field flashing'

There's some info about checking/flashing a brushless self exciting
generator here in a manual here.

*If* it needs flashing it looks like you just need to connect a 12V
battery across the capacitor for a second.

If using a lead acid battery I'd also connect a fuse inline in case
something has shorted.

cheers,
Pete.

if it were that surely it would perform consistently badly. I suspect
a bad joint is more likely, which is generally an easy fix.


NT
self excited field coils are either all on or all off. once any voltage
is genraeted, they build up to a maximum.

However, surely field coils are excited with DC? perhaps there is a
rectifier block the far side of that capacitor that has gone partially
phut.

There are downloadable manuals on the omega wolf website but not one for
this generator.
