Would This Work

[trvlngnrs]

I have a set of 18 volt battery powered tools. Can I use this, or a
smaller 12 volt battery to test different circuits? What I am thinking
of, is connecting jumper wires to the wires at the circuit breaker (TV
antenna for example) and connecting/touching the other ends to the 18
volt battery terminals. This way I could determine if the problem was
before or after the breaker.

Is my thinking flawed?
Would using 18 volts damage anything?
