Don't always agree with Harry; OP may not have a tone generator but

Why would one want a tone generator? A continuity meter (a normal
facility on any multimeter) is all that is required.

I use a tone generator and receiver all the time for tracing data
cables,

So do I but that is when the two ends you want to trace are physically
some distance apart not all poking out of a double back box. B-)

Dave, is your clock set correctly? You seem to be posting an hour
ahead of the rest of the country.

Vintage (1998) news reader doesn't understand the TZ config.sys setting,
it'll sort itself out next weekend. B-)
