T&T: Toroidal transformer question

[Peter Bennett]

How many leads does the toroid have?  If two leads, it could be a
current transformer - do you have an ammeter that shows the current in
the red wire?  If it has more than two leads, but only two are
connected, it is still likely a current transformer.
