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.
A dead battery is the most common cause for a truck not to start. Corroded battery cables is the second most common cause for a truck not to start.
Start the truck then disconnect the battery if it's still running the alternator is good
As long as the alternator works and your charging system is correct, the new battery will start your truck and keep it running.
Very likely an alternator problem; if the alt is not working soon the battery would be drained and the truck would shut off.
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
If it is running on the battery only then that means the alternator is not charging the battery.
Loose cables, bad battery, alternator or starter.
the diodes in the alternator have gone
bad alternator, bad voltage regulator, bad battery, bad connections.
If a Chevy truck tries to start but then doesn't, it might be that the battery is low. Check the alternator also to make sure that battery is charging properly. Some larger motors require a larger cranking amp from the battery to start.
bad alternator ? its not charging the battery
should but what run to long because all power in/on truck running off battery
you need to take the alternator off and have it tested advance auto parts does this for free
alternator and od solonoid
There are a couple of a reasons why a 1994 Ford F150 truck will not start. The truck may have a dead battery or the spark plugs need to be replaced.
It could be the starter in it. It may be weak or need replaced.
check the wiring change the starter relay and clean ignition switch with electicial cleaner.
The starter or battery could be weak. The weakness will cause the starter to turn too slowly to start the truck.
This may be a dumb question, but did you remember to plug your new alternator in? I installed a new alternator on my truck but never plugged it in, so it wasn't charging the battery and kept dying.
Start replacing the 2000 s10 alternator by disconnecting the battery. Remove the air inlet hose, and the serpentine belt. Take off the bracket over the alternator if it has one. Unbolt the alternator and disconnect the wires. Reverse the procedure to install the new alternator.
