It used to be a scam to reverse leads to make them run backwards

Nope, trad mechanical meters just don't care (unless you get inside
the meter case and swap some of the internal wiring).

The "gadget" was an inductor that messed with the power factor of the
load, thus confusing the meter. It didn't make them go backwards, but
it did slow them down.

Now you mention it, thats what happened. You could see the meter slow
down - it was a long time ago :-)
