lets start here

1- I want you to check the battery for 12 volts

2- also check the alternator for charging 14 plus volts while running ? you can use a voltmeter on battery while running with all loads on , like the headligh on the flashers on radio and a/c on then check for 14 plus volts at battery ?

3- what killed the battery , just sitting for few days ?

please let me know

Thank You
