I got a new battery, and new starter, and a new alternator; so, when I go to crank it, it loses all the power like all the lights and power on the dash goes out.

Good afternoon,

I would check the connections at the battery. If the connection is not clean and tight, it will not pass the needed power for it to start.

I attached a guide for you to follow to make sure you clean the cables properly.

Let me know the results when you are completed.
