Very possible. Charge the battery and have it load tested, then put a volt meter across the battery with the engine running. Voltage shown should be above the volts shown on the meter before you started the engine. Normal reading should be around 13.5 and should not drop to less than 12.5 with all accessories turned on (including high beams). Voltage should not continually drop over time either. A steady high voltage reading (14 volts or higher) is not acceptable. . High charge rate indicates either a full field condition in the regulator, a shorted field wire or a bad battery.
Always check belt tension before testing as a slipping belt can alter charging rate.

2005 dodge neon won't start I've jumped it off with jumper cables and take cables off it and it dies. i got another alternator and tried to jump it and it died when i took jumper cables off still????


I would suggest that you have a load test done on the existing battery as the indications are that it has several dead cells
the vehicle starts of the jumper battery but on removing the leads there is nothing with which to keep the ignition circuit operational
alternators need a current from the battery to start charging as they do not have residual magnetism in the stator so when you take the jumper leads off there is nothing to keep the alternator charging hence no power for the ignition circuit.

I hooked up the jumper cables wrong to a Mini Cooper 2005 and it wont start. What should I do?


load test the battery. Test the alternator with a multimeter, it should read between 13.3 and 14.6 volts dc. Test the alternator at idle and rev the engine to 2000 rpm. The multimeter probes are place on the battery terminals. Look for corrosion between the battery and the battery clamps. Baking soda cleans the corrosion.

Daughter called me ..car wont start. checked battery at Autozone...it is good. someone stopped to help them and bang on startere and it starts up. Bad starter. Starter replaced. Next day daughter...


it sounds like you have blown fuse to the Alternator.. I don't know what car you are talking about but they charging systems vary.. But if alternator isn't getting all the power it needs it won't charge. this should be checked.

good luck

Take off jumper cables it dies


You're alternator is dead. Once started the alternator should generate enough power by itself to keep the engine running.

Battery Drain


It sounds like an Alternator problem.
Remember the Battery only Starts the vehicle and runs nominal operations. The Alternator actually provides the electricity to run the Engine operations. With that being said: Start the vehicle, jump start it if you have to. Remove the Negative Cable from the Battery or remove the jumper cables. If the Engine dies after doing this, the Alternaotr is bad and needs to be replaced. When the Alternator begins to die, it starts draining the Battery. During normal operation it is the Alternator that sends a small trickle charge back to the Battery keeping it charged-up.
Let me know if this helped, or if you have additional information or questions. Feel free to contact me at FixYa.com!

Starts and runs with booster cables hooked up but when you disconnect the cables it just dies why


alternator is bad. in most cases when applying jumper cables to your battery if the cars starts and u remove them its casue your stealing power from the source not the alternator.

The battery light was coming off/on..then all the inside lights dimmed then the car died out and anti lock was coming on and not letting me change gears


The alternator is most likely faulty. Disconnect the negative terminal on the battery. connect jumper cables to the positive post and the Engine frame. Start the vehicle. If the vehicle starts, disconnect the negative jumper cable. If the vehicle dies, and most likely will, remove the alternator and take it to Auto Zone and have it tested. If the vehicle doesn't die out, replace the battery.

Starting problem, battery? alternator??


Unless you have good jumper cables it would start easy since I didn't get in on the begining of this I will assume you have a bad connection tothe starer or a bad starter if it drags.
