I replaced battery on my subaru legacy a few months ago. She has been running fine with no issues at all. I haven't driven in a few days. I went out this morning and she's completely dead. No lights/radio or anything left on. I tried to start her up and nothing. No dash lights, headlights and no turn over at all. I don't know anything about cars. What could the problem be?
you could either remove the battery and charge it up or jump start off another motor to try and get it running,when it goes check your charging rate with a voltmeter,you should get 14v+,any less suspect alternator
