Bobby, If I write no power present it's because I did check for voltage. Easiest way is with a stick type volt tester which I carry on my belt. If I've got the time I'll unscrew the bulb and check the socket. I don't take time to open fixtures. I will sometimes also use a tic tracer or volt meter, again depending on time and curiousity. To ignore such situation on the report and to tell the client that it's typically a burned out bulb is an assumption, and usually you'd be right. But if you're not...... I've gotten into the habit of trying to write exactly what I know or found. I don't make big issues of lights not turning on or no power somewhere. I just raise the question - is it a bulb? a switch I didn't find? or some other concern? I leave it up to the client to follow up with the seller or make his own assumptions.
