| Most likely there is a loose connection somewhere in the circuit between the panel and the first dead outlet.
This can be a loose screw terminal on an outlet, or a loose splice in any junction box.
With the home being so old, you may have Knob & Tubing wiring hidden in the walls or ceilings, with Romex or BX cable exposed in the attic and basement.
The connections for K&T wiring are all buried in the walls/ceilings.
Each box, light, outlet, etc in the circuit will need to be opened looking for this bad connection.
A voltage tester will come in handy, without it, you will only be guessing hoping to find the obvious problem. |
