Power outage in vehicle

Friends, about 6 days ago, I had the battery changed in my 2013 Tepe Zenit vehicle, the time passed, I went to my vehicle to start it, I opened the door with the remote, when I turned the ignition on and started, there was a power cut. There was no such thing before the battery change, I checked the terminal, it was fine, a few After a minute, the electricity came back, I would like to thank my friends who will show me a solution to this situation, with my best regards.

Sir, have a look at the fuses of the vehicle, is there a place that blows the fuse, don't leave an open cable, cover them all with tape, it will cause chassis electrical problems
