Answers from the Automotive Experts

Amanda J. Pierce, MBA Jane, Thank You for writing into AskPatty!! To address your concern; you may need to have your alternator tested. You battery is a sole function for starting your vehicle, to keep it running the alternator is used. When you have a faulty alternator, possibly from a worn stator, this can prohibit your vehicle from staying running. Hope this helps!! A. J. Valle

Judy Curry, Co-Founder and Vice President of Marketing at Currys Auto Service Hi Jane! This sounds like you still have a bad connection either on the positive or negative cables (provided the battery is fully charged) I would recommend performing a voltage drop test across both cables then I would check and clean all connections, and measure voltage actually getting to the starter. Once these tests are done I am sure the problem will be found. Good luck and thanks for your question! Judy

Lori Johnson, Owner and Instructor at Ladies Start Your Engines Dear Jane, Sounds like you have just enough juice to power accessories but not enough to start the vehicle. If you have a meter, put it on Volts and check the battery with the key off. You should see 12.6, if not, you need to charge the battery. Also check all the connections to make sure they are tight. Check at the terminals and at the ground. If you can jump the vehicle take it back to where the work was done. They should be able to diagnose your problem.
