I parked and shut my car off, and everything shut down completely with the key stuck in the ignition. No power at all. I’ve pulled and looked at the four fuses you recommended; they look fine to me. But with no power, or no tester. I’m at a total loss! I replaced the battery less than a month ago and have had no issues until now. Do you have any idea what I can do? Any suggestions will be gladly appreciated!

If you have no power to anything, first confirm the battery cables are in good condition, not loose or corroded. If they are, we need to test the battery. It could have shorted internally and failed.

Do you have any means to test for power? I looked at the power distribution schematic and found that battery power comes directly from the battery to the fuse box. For all the fuses to have failed at once is very unlikely. That leads me to think either we lost connection at the battery, the main ground from the battery to the vehicle has failed, or the battery itself has failed. The only way to do this is if you have a means for testing for power, other than a visual inspection of the battery cables.

Let me know. See pic below and you'll see what I mean.

Take care,
