Even a new battery cannot start and run the vehicle for long without the charge it needs from the alternator. The battery has a certain amount of reserve power meant to start the vehicle only, then the power supplied by the alternator keeps a constant flow of power going to the battery to keep it charged enough to run the electrical system of the car. The electrical system, especially in late model vehicles pulls a large amount of electricity, so without that constant flow to replace the high draw, the battery is drained of its reserve. If you have driven the vehicle with a malfunctioning alternator, then parked it, chances are there is just not enough power to turn the vehicle over and start it again, as it has been drained completly.If you charged the battery on a charger, it would,(if a bad alternator is your problem)start and run the vehicle again, but just until the battery is drained.
The answer is no . The battery starts you vehicle , the alternator charges the battery so if your alternator is bad your battery is not receiving a charge which will cause a "no start" condition.
Start the truck then disconnect the battery if it's still running the alternator is good
Very likely an alternator problem; if the alt is not working soon the battery would be drained and the truck would shut off.
As long as the alternator works and your charging system is correct, the new battery will start your truck and keep it running.
the alternator is bad
the starter,battery and the alternator are good,icheck and change the the wires but the light inside the dashboard,the headlights come on but the truck will not start.
The most common reason for a vehicle not to turn over is a bad alternator. If the alternator is not charging the battery the engine will not start, regardless of the battery age.
Your alternator is not recharging the battery and is defective.
Well it maybe that the battery is to small for the truck or the alternator is bad
Loose cables, bad battery, alternator or starter.
If it is running on the battery only then that means the alternator is not charging the battery.
the diodes in the alternator have gone
