Electrical & Radio Interference Questions

Just finished reworking the trunk area (what a bear of a place to work in) and now moving into the bumper storage area.

1. I need to unhook the main ground wire to paint the frame. Running a line to it and out to a ground stake next to the trailer. Any problem with that.... Also.....

2. My overhead lights are on the blue circuit that also feeds the radio and control panel. The more lights you turn on the more buzz the stereo picks up. I took all the light switches apart and cleaned them - that helped some. Any ideas.....

Sounds like a noise filter may do the trick. Check out this link. The principles they outline apply to any 12v radio system.

I have the same problem only its with the am side of the radio. The filter caps (capacitors) are bad in the Univolt. I have yet to see anyone post a schematic of a Univolt or I would have pulled and rebuilt mine already.
I really have never even seen who the manufacturer of the UNIVOLT was.

One problem already I see (from the article Mello Mike posted) is that the original antenna does not have a ground wire - the new replacement ones we just found do.
Not sure I want to try feeding the new cable but that may be necessary.

I'm not sure what converter I have - can't see the label. It's not the big metal box Univolt but may just be a newer version. It's black plastic housing with slightly inward sloping sides toward the top. The fuse panel has been moved out on it's own where the Univolt apparently had the fuse panel inside. It does still hummmm like a Univolt. The Power On indicator light on the panel does not work which I think is an indicator of a replaced converter...?
