Sounds like the power is at the fixture.

But of course, since the light goes on.

Black sends power to the
switch and red is the switch leg which carries power back to the light
when the switch is on. The neutral remains at the the light fixture.
Most likely there isn't a neutral at the switch.

But he says there is a power outlet at the switch, and it works when the
switch is on.

Unless I have misunderstood the original post.
