My solution might be a little different. With the lights in the rest of the coach on take a positive and negative wire from a good source, remove a bulb from one of the bad ones, and first try connecting the negative to the socket side. Alligator jumper leads help.
If the lights light with the negative connected, you have a return negative problem. If nothing happens, remove the negative wire, and try the positive wire to the socket bottom. If that makes them work, you have a positive wire problem.
Start with figuring out whether you have power there, and no negative return, or no power, but the negative return is still good. Knowing that, you now have only half a problem, and the closest dead light to where the good ones are is likely the failure point, or it could be at the last good light too.
