Hello. I am adding a ceiling fan to a bedroom and when I took out the existing light fixture (florescent work shop/office lighting) I found a mess of wires. The florescent work shop/office lighting is not original and was installed sometime after the original lighting. As you can tell from the photos this is very old construction. There are a total of 4 sets of wires coming into the box (1 assumed to be coming from the switch, 3 others going to unknown locations). When I took the old fixture out, the hot wire was connected to the black wire all the way on the left in the picture (assumed to be coming from the switch). The neutral wire was connected to 3 other neutral wires all the way to the right. The previous light worked without any issues. It appears to me that the neutral coming from the light switch is connected to the 3 other hot wires. When I tested at the switch both the hot and neutral were hot while the switch was in the "off" position. When I tested at the fixture everything was hot except the group of neutral wires on the right regardless of the switch position. Again, everything was working fine before. Is there a reason that neutral would be connected to the hot wires? Should I leave it as is because it was working before or should I move that neutral to be with the other neutral wires? I am not sure if this was DIY'd improperly or if there is be a reason for it. I am a novice as my electrical experience consists of installing 3 light fixtures, 2 ceiling fans, replacing some receptacles, moving a few light switches, and adding some lights to a closet. Any and all help is appreciated. Thanks!!! [ATTACH]53590[/ATTACH][ATTACH]53591[/ATTACH]

basic question: Can copper ground from new light fixture go directly wired to rigid copper ground in junction box of light? IF it must does rigid box ground go to screw or new light grnd (they both connect) ? [I]Details[/I]: I have what is prob' a simple question and have googled a lot tonight but we have never done home dyi of any magnitude and this was our first time w/ wiring anything. We put up a new kitchen light fixture in our 1979-1980 apartment (w/ permission of course.) Our junction box was a mottled black color, I assumed plastic but not sure. There was no green screw in orig' light fixture bracket just the raw copper ground (and black and white). We wired the new light fixture and new bracket and put copper ground to old raw rigid copper ground wire with screw on cap and ele tape around that. Skipped green screw on new bracket Is that ok? :confused: IF I rewire it does the rigid junct box ground go on that little screw (how) or the thinner ground from new light then connect to rigid org? Much appreciation for your expert knowledge as I do not want to be causing a fire! :eek:
