    2008 Prius. While taking the 12 v battery out, my daughter said the end of her socket wrench briefly touched the other terminal causing a spark. Now no dash lights are showing and the car will not turn on. The 12V battery shows full charge with my meter. I have checked the AM2 fuse in the engine compartment and fuses 15 and 30 under the dash. Any other fuses I should check or things I should try?

    I have Techstream, but cannot check codes due to the above issues.

    Well this is why you want to be careful with daughters and wrenches. If you're 12 volt battery has 12 volts try undoing the neg terminal crackling noises make the door open red lite up when it does your display will work when you open the door step on the brake and push the button.

    Thank you. I tried another meter. Battery registering 6.5. It has set for about a week. Charging now. We'll see....

    True. One of the hazards of her living ten hours away.

    or, perhaps, diligent to introduce children to wrenches while they are growing up

    I started with mine at months of age seriously . She had some snap-on wrenches before she had baby toys clean new snap on steel wrenches she actually like them better than the play school plastic toys because they made neat noises when they touched together and things like that she played with till about 7 or so still has them today . She works on microelectronics in the computer industry she uses tools so small and magnifying glasses so powerful it's like surgeon working on heart valves or such. Never had huge interests in girl stuff neither did her mother .

    The snap-on wrenches work great for teething because they're nice and cool to your gums when you apply them . That's why I gave them to her new nice and clean.

    At 9 I took her to Athol Mass to real tools being made . She loved that trip . Seeing machine tools turn spiral strips of metal right on the floor was really cool .

    I sense we have taken a rabbit trail... lol!

    With no alternator, what would cause the 12v battery not to charge?

    Thank you. Spot on! Bad battery. I took it to Advance and they replaced it.

    Now with that resloved, it is displaying POA08 and POA09. Bad inverter. I replaced the one my 2004 Prius about 8 years ago. No problems since.

    Any new information on replacing the inverter?
