Help replacing fluorescent light fixture - 2sets of black and 2sets of white wir
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

Since both lights quit working at the same time it is likely the power not getting to the lights and the lights are probably still good. Do you have a multi meter? If so you can check to see where power is stopping. It could be the breaker is tripped. The switch is bad. Maybe a loose connection somewhere.
That fixture is probably passing power through to the second. In that case you would connect all blacks together (two from the house one from the new fixture) connect all the whites together and the bare copper conductors together with an attachment to the fixture's ground if it has one.
