Re: How to use an inductive probe?

Where we are they put them out in the garage, surface mounted on a gang box
up high out of reach.

Try removing the doorbell light bulb and see if it works without it.

| Our door bell stopped working a few months back and I've been trying to

| 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
| inductive probe.
|
| 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!
