My stang has developed gremlins - help, please

your dash has a ground

In the realm of I feel stupid, I went back and opened up my map light and found I had 12v on one side and a good ground on the other, leading to the epiphany that the bulb had burned out! So too the both courtesy light bulbs, and, lo and behold, the fuse on the back of my kenwood double din. Oops. Seems so elementary to check the bulbs, I guess all 4 quitting simultaneously made me look for a conspiracy. Im sorry for wasting everyone's time. 

Thank you for directing me back to look for the obvious answer

You are correct, Midlife, that is what I was trying to say when I said it gets its ground from a common point, should have explained it better.
