Wow, I have got an electrical nightmare. My house is about 50 years old. It has had the wiring modified at least 3 times somewhere in the 70's & 80's and in 2000 (so some rooms are code, and some are hazards). At some point it was upgraded to a circuit breaker configuration. Well I had satellite TV installed a month ago, and that is where it got weird. The installation is in 4 rooms, spanning the 5 decades of electrical modifications. When I touched the metal housing on the reciever box, and another powered appliance, I got a "mild" shock. I assumed it was due to something with the satellite install. The techs came out, found the system was not grounded and ran a ground to my plumbing. The shock seemed to go away. But then one of my recievers in the other room died. When they sent me a new one and I tried to install it, the thing gavce me a very violent shock (10x more powerful than the previos issue) which tripped the circuit breaker and totally FRIED the new reciever (like smoke pouring out!). That same day, the remaining 3 recievers stopped working! I am guessing there is some major problem with my house wiring, which is brought to light by the fact that all 4 wiring systems are interconnected by the coaxial line. I bought one of those light up GB testers at Lowes today to at least find out tonight if things are reversed or anything.
So, that being said:
Is there any DIY way to make my wiring safe?
If it is beyond my skill level, will an electrician be able to fix things without gutting my wiring and costing me thousands of $$$?
TIA for any advice,
