Default brushless alternator?

The capacitor is open circuit so that's an obvious problem


I would also question that . . . oil filled caps don't incorporate
fuses, real oil filled caps are "self-healing" and damn near
indestructible. It is possible, but not likely.

And all caps are open with a DC ohm meter - except lossy electrolytic
types.

Electrolytic caps can also be used in induction alternators and they
can and do fail - the caps have to withstand a high circulating
current - uses no power (ideally) but the current has to flow through
the cap and the cap has to be able to handle that current.

Home power alternators look similar to induction generators and work
similar but incorporate permanent magnets in the rotor - no regulator
except control the speed of the engine driving it to keep the
frequency correct.
