I am replacing fluorescent light fixture. The previous owner had 2 fluorescent light fixtures connected with a single switch. Those lights stopped working. I checked its not the tubes that were just bad. So Home Depot Associate said that probably the ballast were bad and suggested to replace the fixture with LED style fluorescent fixture.
So I took one of the fixtures off. It had 2 sets of black, 2 sets of white and 2 ground wires coming into it. In my wisdom I put caps on 1 set and connected the other set to the light. This did not work . So I was going to try the other set. But decided to search as why I have the 2nd set.
Q1: Based on the google search it seems like that the 2nd set is to connect the 2nd fluorescent light fixture. So I am thinking to connect both sets of wires to the 1st fixture. Thoughts?
Q2: I am also having some thoughts as what is the possibility that 2 sets of fixtures have gone bad at same time. May be I should do something else.
The house is build in early 1990s
