Q: How to use an inductive probe?

Our door bell stopped working a few months back and I've been trying to
figure out what might be wrong. The doorbell button has a built-in
light which is off now. I replaced it with a new button and the new
button doesn't light either. That led me to check the voltages at the
doorbell unit and it has no power.
I understand that doorbells run at a lower voltage which is achieved
via a step-down transformer. My problem is that I can't seem to locate
the transformer. I checked at the obvious places (near the furnace,
near the fuse box, behind the doorbell chimes) but haven't found it
yet. My next option is to trace the wires from the doorbell using an
I obtained a Progressive Electronics Model 700C kit which include the
200EP Inductive Amplifier and Tracer 2 Model 77HP tone generator.
Unfortunately I can't locate the instructions to use the unit. I see
the Tracer 2 tone generator has two alligator clips (black & red). Do I
just connect one (red?) of these to the wire that's supposed to come
from the transformer to the door bell, set the switch to "Tone" and
then use the inductive probe to follow the wire or do both wires need
to be connected?
Appreciate instructions or suggestions you might have. Thx!
