It's ON-topic for s.e.basics, so no worries on that account. The only
OFF-topic questions on s.e.b are those that don't involve electrons in one
way or another. ;-)

I'd look at the physical condition of the relay, like dirt or some
obstruction; and check all of the connections in the relay's coil
circuit. It sounds like it's not pulling in fully.

It used to work, and this symptom appeared recently, right?

Thanks,
Rich
