I recently installed a Generation II Dave's Rack on my Jeep. Upon completion and on it's first drive I noticed that the turn signal was blinking either very fast or very slow and sometimes would change on it's own from fast to slow or reverse on it's own but that's not yet the problem. When I got home I took the rear drivers side tail light assembly off to check the ground that was there as per factory settings(between the body and the assembly). Be advised that in order to install the rack I had to place a metal plate inside of the body with screws that protruded out and then nuts were screwed on from the inside in order to reinstall the assembly. Now first let me say that all lights in the front are fully functioning as far as brightness goes and that includes fog lights. But because of the problem in the rear they are subject now to the speed of the blinking. The real problem is that ALL of the lights in the back (reverse, signals, hazards, brake lights) are just dim and weak now. They all light up weakly, they all blink and respond to what I want (reverse lights come on in reverse, brake lights light up, tail lights on with headlights) but as I said they are weak and they blink erratically. Also I would like to note that recently my ignition has been acting funny as sometimes when I turn the key back to off the engine keeps running although I have found that with careful turning it's not really a problem. The ground wire just doesn't seem to make a difference at all. Whether it is making contact with metal or not the lights do not change at all. With the headlights on or off it changes nothing about the weakness of all rear lights. That is as much info as I can give at this time. Any help would be appreciated.
