I have to replace a fluorescent light fixture in my basement. Everything, housing, ballast , is going. I've done basic re-wiring before. Nothing more complicated than turning off the circuit breaker and reconnecting black to black/white to white. It has a power feed going into it as well as the line for the microwave oven and also individual black/white wires that connect to a transformer for the doorbell. When I pulled off the bottom plate of the light fixture, I see the following connections: The Black wire from the power feed is tied to the black wire for the doorbell transformer and the black wire for the microwave. The White wire from the power feed is tied to the white wire for the transformer doorbell and the white wire from the ballast. The Black wire from the ballast is tied to the white wire from the microwave. The ground wires are tied together and attached to a screw. QUESTION: I want to put all the connections into a new junction box and just have a single line coming out to the new light (which may not even be a fluorescent). So with a power feed line, the microwave line, and the indiv black/white transformer wires going into the new junction box, do I just tie all the blacks together and all the whites together? thanks

I have a light outside my garage that apparently was never wired in, as the wire from the light comes inside the garage and hangs there. I want to run the wire up into the attic and have it controlled by the same switch that controls the front porch light. I have been in the attic and located the wire that goes from the front porch light over and down to the switch. The existing wire is 1950's NM fabric covered with no ground. I have purchased new 12-2 yellow-covered with ground to run from the garage light. Two immediate questions: 1. Can I simply cut the line in the attic running from the switch to the front porch light and tie the new line to it, all three blacks together and all three whites together...if I do so inside a new junction box? 2. If so, how do I handle the grounding wire coming from the line from the garage light into the new junction box? The process seems easy, but I'm afraid I may be over simplifying it. Advice is much appreciated!
