95% sure it would be your alternator... If you have a "Batteries Plus" store anywhere near you they will do an amp check for free. the reason for the light coming on above a certain speed could be due to the metal brushes inside the alternator wearing down and not making good contact, because of the higher speed at which it is spinning you notice it more. You can kind of do a test on your own without tools also, but don't rely on it soley though. Turn the truck on in idle position, have the headlights off...then turn on the radio, the heat, make sure the dash lights are up as high as they will go, turn on the dome light ( that could make it harder to notice the result). Then turn on your headlights and pay attention to the radio and the dash lights.... If they dim down for even a second you alternator is on the way out. If they dim down and stay down you better get it changed because if you down it will do nothin but **** all the life from the new battery you have and you wiil have to replace that as well.

You need to get a scan tool and see what codes it is throwing when the light comes on. This will eliminate the needless replacing of parts by guessing.

Car not start after overheating


I was driving at about 65 mph on the highway and the first thing i noticed was the trac off light blinking on and off. Also, there was some sporadic sound coming from somewhere and thought nothing of it. Then, I couldnt accelerate anymore and pulled to the side right away as the engine was thumping. Opened the hood and saw smoke coming out. I had also put antifreeze in the car a few days ago and it was bone dry. So apparently, I have a leak. I tried to start the car again after an hour and half with antifreeze in the car and nothing. Anyone have any suggestions??? I should mention that i do hear the engine trying to ignite but it sounds like its misfiring and it won't start.
