I changed the battery and the alternator, now there is nothing at all happening on the dash or when I try to start the truck. Battery is fully charged, and the alternator has been tested. Is there something I have forgot to do?

Did you check the ground to the engine block? Also, do the lights, horn, brake lights or anything work?

Ammm. There are two exposed wires in the back that are connected to the alt. And then the plug in on the side. I'm not near to the truck, but the door buzzer works when the key is in. May it be a fuze? I will be working on it again in the morning, please help.

Let me know if the lights and other electrical components are working. I am at work now (aprox 7:30AM eastern time) I will check my email again around 11:00 AM) Make sure the ground to the engine block is clean and tight and the battery terminals are the same.
