Default generator problem(s)

and this bit of magic:

This method seems to have some flaws.

It certainly will not work with a variable speed drill

It appears to state that drills have permanent magnets (Ac powered
drills don't)

It assumes that a drill will generate some power when spun by hand,
this would be a very small amount of power.


Get a large 1000w elec drill plug it in and run it up for a while.

Now Connect a 5v DC meter across the plug L + N, and with it still switched
on spin the chuck quickly by hand.

Result ?

Whether this voltage would be large enough to kick the exciter into action
is another issue,which would also depend on the design of the alternator.
