asked by on

Hello, I would suggest testing your alternator. If jump starting will start your vehicle, use a multi meter to test your alternator while the vehicle is running. Good alternators test in the range of 13.8 to 14.2 volts. If it tests below that, repair it or have a qualified professional perform the job. If you need assistance, a repairman from YourMechanic can stop by to replace your alternator.
