Wanted to get some input on something.
I am a line tech and had an installer call me today saying he had voltage on the cable. After trouble shooting and checking the house out heres what i got ....and yes i read other posts asking similiar questions but its hard to tell if they checked something properly.
Voltage source is 100% from the house its an aerial drop and when completley disconnected from the house i still have the issue. There are only 2 outlets in the house 1st floor and 2nd floor and both have identical issues. I disconnected the input cable from the cable box and made a small jumper with a connector on one end and screwed it on the box the other end is stripped back exposing center conducter and braiding. I have 65 volts AC on the cable jumper plugged into box but only when its plugged in to wall outlet. I also tried using my VOM grounding to a different outlets ground prong hole and touching the cable with my other lead in it picks up 83 volts AC. The house electrical wiring is realy old and i could see some poorly done splices in the basement. I also found another ground rod on the side of the house about 20 feet from cable ground that had 1 small ground wire going to it and looks like it enters house where the electric panel is. (behing siding for 6 feet so cant verify for sure) whatever it was it was just barely making contact and so loose it fell off. I cleaned up the copper and regrounded with a new clamp and tightened down but it did not fix issue. I would say house is not grounded properly and thats the issue. But how can you determine if the house dropped a neatrul or the outlets are just not wired properly? The breaker panel is the oldest one i have seen in a long time too. Its only about 20 inches tall and 16 inches wide there cant be more than 10 breakers in there. I hated to do it but i had to leave the drop disconnected until they got an electrician out to fix issue. I just wanted to get peoples feedback if they have had a similiar situation or have any info that would be useful. And yes i am aware that certain cable boxes had AC issues and a bad box/vcr could cause this but this has been ruled out. Just for good measure we plugged box into neighbors power and no AC backfeeding.
