96 has no electrical power at all

New guy here coming from the second gen world. The gf's little brother has a 96 with a 2.7 and a five speed and he said it wouldn't start. Tried jumper cables and leaving the battery on a charger for a while an I don't know where to start. Absolutely nothing has power. No buzzing no clicks no lights no horn no radio no flashers nothing. I don't see any melted or broken wires so I guess the next step is fuses or relays or something. Idk I'm hoping someone has a suggestion lol.

 

Battery ground

 

Take battery off and clean connections. Put good battery in and try. Can just take battery out of your vehicle and see.

 

I got it. Took the negative cable off at both ends and cleaned it up and cleaned the positive terminal and it fired right up. Thanks for the help I can't believe I overlooked something so simple

 

something similar to this happened to me but it was because I didnt reconnect the negative after resetting the car. an hour later when i realized what it was i felt pretty dumb afterwards

 

That's one reason we are here so we can help each other. Thanks for response.
