Plugs not working
I have a 1930s house, my 3 living room plugs connect to my 1 dining room plug, last night they just stopped working in my living room but the one in my dining room continued to work. Changed the breaker switch, checked the dining room plugs they were fine, plug 1 that went out had some naked wires that I covered. I plugged in an outlet tester and it does a SLOW blink. Ok moving to another living room plug, plug 2, I had my alarm plugged in, I go to plug in my outlet tester into plug 2, it shows SLOW blinking, I unplug my alarm system, it stops blinking and a bright consistent light is on the outlet tester. I plugged another outlet tester into plug 1 (thats the one that stopped working originally) and it had a bright consistent light. Ok odd. I plug my tester into plug 2 and a lamp in, it starts blinking again, then plug 1 ALSO starts blinking. Ok I changed out the ENTIRE plug 2. Now it shows slow blinking still and only left side of the plug actually has any power. What could this mean? Broken neutral wire? Idk what else it could be.
