Battery died a few nights ago, jumped it and it was running good. Shut it off to try it on its own. Nothing. No lights on dash, radio, headlights, door locks trunk, alarm light. Only thing on is the door ajar indicator and ding that keys in and doors open. Started checking fuses under hood. Nothing alarming there. Checked inside fuse panel and no power to all the fuses and relays. Where do I start?

Good afternoon,

You need to start with a good battery that has at least 12.4 volts. You need to either charge it or replace it.

Then use a voltmeter to check the voltage at the battery with the engine running.

The battery has been tested, still good battery, with good charge. Even with jumper cables hooked up to car problem above still occurs. Tells me it's not the battery. Please reread original post.

Okay, good.

Now, what is the battery voltage at the fuse boxes?
