What's the batteries voltage? Are the POS NEG cable conn tight? When you turn the key where is the battery gage needle pointing? While driving, where is the gauge. While driving, your battery should be charging. If not, the problem could be the alternator. Most auto parts stores will test the battery and alternator for free.
