Have some Lights, but not others, Help!

Ok, thanks we will try a few measurements for power in the right places that you suggested. The link describes the pin fix in the barrel connector. My connection there us sturdy and strong, no loose pins.

I get the IVR. I have had several A bodies, but none has developed this feedback/loop. What is interesting is that if you follow the PC pattern from the IVR, it looks as if the lower voltage feed goes to other places on the board, and voltage even travels to the screws holding down the PC to the housing with smaller screws.

I think we have a reverse polarity issue. Another thing I noticed is that the LED bulbs I put in the new sockets have a polarity functionality. You need to set the bulb in the socket a certain way or the light wont work. I never knew that to be the case. We just need to find out why we have higher that normal voltage on the back casing and why when it hits ground on the car, the lights go out instead of completing a circuit. Thanks for your help
