Hi. I'm sorry I should of posted with more details about the problem. This might be a little confusing to read as I may not be explaining it well.
A year ago before all these problems I originally had a 20amp breaker, and I replaced it with a 30amp breaker. It's been working fine for about a year so I don't think this is related but I felt I should mention it.
Several days ago I lost power in the lights and outlets in the main bedroom, bathroom and little bedroom all on the same breaker. I was running 1000 watt lights and other appliances from the outlets.
Now I'm getting a hot ground reversed reading from the outlets and no appliances work from them.
The problem seem to of started when a fish tank heater broke and I think it shorted out and stayed shorted out in the water for a long time, possibly days. On the outlet in the bedroom I'm getting half signal between ground and hot. Reading of 017 continuity digital meter (0 is full continuity).
When I flip the light switch in the bathroom, the voltage drops in half.
Using my outlet receptacle tester shows hot ground reversed.
Readings are 120v but when I plug something in it goes to reverse ground and nothing works.
I assumed it was the breaker, but I replaced the breaker and the problem still exists with no improvement so I don't think it's the breaker anymore.
I turned the breaker off and started testing continuity between the panel, sockets and switches and that's when I got "bleeder" / weak signal (half the volume on the tone generator) between the ground and neutral.
I then pulled the neutral and the ground thinking that would stop the problem but it didn't.
I disconnected one of the outlets in the main bedroom which killed the two other plugs in the bedroom and all of the bathroom and the smaller bedroom lights and plugs but the problem hasn't changed.
There's only one other outlet now (to the breaker box) which is outside. This outside socket got flooded with water and when I plugged in my receptacle tester it shows three lights on that socket although the third light is dim. I think this outside socket is the first socket in the line and I'm assuming following it is the outside light and inside hallway light which both work.
I had a friend make me a 4 110v gangbox which I could plug into my 220v outlet and I'm getting hot neutral reversed with nothing plugged in it reads 122v. Receptacle tester reads hot neutral reversed. Unplug receptacle, plug in digital meter reads 122 volts, I add the receptacle tester with the digital meter and it drops to 118v. If I plug in add a desk lamp it switches the receptacle to hot ground reverse, and reads digital meter reads 37 volts.
I tested the gangbox and it seems to be ok unless I made a mistake testing it.
Supposedly there's a GFCI somewhere but I can't it anywhere.
This is a manufactured home but I don't think that matters?
What does this problem sound like and how can I find it and fix it?
How can I test to see if it's my breaker or the main (electric companies) that's the problem?
Is it on one of the lines and feeding back or is it the neutral bar possibly touching the box?
Thank you for your help and I'm sorry if I wasn't clear.
