the time needed to start, it will do exactly what you describe
quite quickly.
So, at the very least, you should check the AC voltage on the
start cap
using a meter that reads only AC (not the DC omponent). It should
go to
0 VAC once the motor is turning at normal speed. If not, you'll
have to
disassemble the motor and determine what's going on. And have
your safety
goggles on while doing it!
That's a really good point, Sam. I have no idea if this motor has
that
type of switch or not. It's a Westinghouse 1/2 hp motor. Is the
switch internal to the motor, or might it be external? If it's
internal, then I really doubt I could have gotten any grease on it...
but if external then I suppose there's a possibility.
In any case I'll buy 2 new caps since they're only $8.

I've seen a variety of those types of switches.
Air pump driven, Magnetic Drag driven, bearing slip driven etc.
all usually have a return spring or something to force the switch
back into it's starting point again. Most common one's i've seen are
magnetic and get pulled from the shaft when it's spinning. you might
want to pull the back cover off the motor to make sure the mags still
are there or have some life in them. Heat over time can kill them and
thus not switch off the cap also, also a fused set of contacts don't
help;
Hi...
Might even be a simple centrifugal switch, in which case grease might
be enough to bind it up.
Take care.

PS - REAL programmers use copy con.
i thought they used a numerical HEX entry key board!
When I started out we used switches, one per bit.
Yeah, but you had 0's and 1's to work with. When I started out we
only had the 0's.
AND - we had to whittle our own chips.
Take care.

REAL programmers keep getting confused between Halloween & Christmas
(Oct 31 = Dec 25).
