Hi everyone, i am having electrical issues with my truck. tried to start it one day and wouldnt, i noticed the seat belt buzzer was weak and interupted (power to the whole truck acted the same). replaced the silenoid, solved that problem. now i can atleast start it, but there is no Electrical power ex: radio, lights, aux... although it will flicker on and off over bumps, different levels of acceleration and slamming doors???? so it never stays on constant but everything works when it does. Thanks for your time everybody!!!

Start by testing the ignition switch could be heating up and breaking open
