help testing old wiring

i read somewhere that one could check old wiring by turning all the switches on and unpluging or diconecting all electrical loads, after doing that if disc in the meter still moved there was a problem [high resistance short]
Having done this [house has knob & TUBING WIRINg]found that disc was turning very slowly,by turning the fises on and off one at the time the circuit most used in the hose seem to case this QUESTION IS THERE A REAL FIRE HAZARD THAT REQUIERES IMEDIATE REWIRING OR IS THERE ANOTHER WAY TO DOUBLE CHECK THE OLD WIRING HEALTH.

THANKS A LOT PAPI

 

Call an electrician. This makes no sense. GFCI's could make your meter spin. This is not a method of checking your wires.

 

Tnx a lot for help,is there another way for me to check the health of the old wiring inside the walls?

Experience is the only thing that I know of. Look at the wire in the panel. Is the insulation falling off of it when you touch it. How old is the home? what kind of wire is it. Call an electrician and have them give you a free estimate on what he thinks needs to be replaced.
