dc, Welcome to the forum
Was there an existing ceiling lamp fixture connected to a wall switch, before you installed the new chandelier?

Easiest way to know which black wire is which, do a continuity test from one of the black wires to the outer part of the light socket. If it passes, then that's the neutral, if not, then the other one is neutral. You can use a multi meter with continuity test feature, or use a battery flashlight bulb.

Are you SURE that those are your only wires?

I have a feeling that the chandelier has (2) black wires and (2) white wires. You found the blacks, but the whites are tangled up below.

It's common for fixtures to have multiple sets of wires coming up out of them, they need to be spliced together in the box.

What is in the center of the chandelier? You see where the two wires with the wirenuts on them are going? What is underneath that?

Second, do you see that bundle of white and the bundle of black wires spliced together? Give those a pull, make sure that there isn't a black and white pigtail mixed into those wires.

dc, You have a Fluorescent Light fixture.
A chandelier is a branched, decorative lighting fixture that holds a number of bulbs or candles and is suspended from a ceiling.

Your pic shows the ballast wiring that is required to operate the fluorescent bulb..

Your ballast wiring does not care about black/white polarity.

Connect one of the fixture orange capped wires to the white wire in the ceiling box that was connected to your original ceiling fixture.

Connect the other fixture orange capped wire to the black ceiling box wire that was
connected to your original ceiling fixture.

dc, Thanks for posting the chandelier Pic.
Very cool, can you post a Link

You somehow now have a short between the black (Hot) and the White (neutral) or a ground.

I would completely remove the new chandelier, find and correct the short so that the fuse does not blow, then reinstall the new chandelier.
