MEGANE DOESN’T START JUST CLICKING NOISES

[Jezzymate]

Hi!

I have replaced my intake on my megane 2 this afternoon. Thinking it would be a 10 minute job it ended up being a 3 hour job.
After finally installing my cold air intake, the car doesn’t start…..in the beginning I had to remove the battery and the ecu to get to the old airbox to remove it. After checking and placing everything back, the car was just dead. I tried to start it with cables, the display comes on, but when i try to start it i just hear a clicking noise.

can someone help me find the problem?

ive attached a video, please watch it.

are the fuses on the battery ok?

Have you got a multimeter to check the battery first and make sure it's good and has enough juice to start the car?

Looks like low voltage.

Check the cables have a good connection on both cars.
