No power to rear marker light
I am in the process of changing out the marker lights to LED. I must have pulled a little too hard on the wire coming out of the skin to get enough for a connection to the new fixture and now there is no power there. I took the fixture back off and confirmed with a meter, there is no power. I am thinking I will have to go into the skin from the inside corner to fix it. Luckily there is a cabinet in that corner and I have measured to confirm the wiring would be behind the cabinet. The rest of the lights still work.
Before I start dismantling everything, does anyone have any words of wisdom that might keep me out of more trouble than I am in already?
