So I had just gotten done replacing my clutch, went to go and put everything back together electrically wise. All grounds reconnected and contact is good not corroded. There's a brand new battery in there. A brand new alternator just replace the Ignition switch. All the wires are good, all the fuses are good inside the car and under the hood. But I am getting no electrical power to anything in my ca;r lights radio inside lights dash lights nothing. Absolutely no power.

Hi,

If you have a charged battery and nothing works, it is either one of the main grounds or no power is getting to the power distribution box under the hood. I attached 3 pics below. The first shows the main grounds and the second and third show the power in to the fuse box. First, confirm there is power to the box. If you note in the pic, nearly everything is a fusible link, so it won't be a traditional fuse. I added pic 3 just to indicate the box's location.

Once you have confirmed power in, start checking for power to fuses and relays to confirm there is power.

Also, I would check continuity to ground. Make sure nothing is internally damaged as far as wiring. I have seen the wires break internally under the insulation and appear good, but in reality, they were bad.
