Thanks so much, pianorocks06 and Travisstorma. I will just leave it then and mention it next time I take the 4runner into the dealer. I also have a feeling it is common here because it is very dry. Especially at night, whenever I put metal to metal I see a small spark. I also get a shock from touching metal.
I just changed out my 2007 Prius battery which was quite involved so I do know to attach the positive 1st. I was watching the Autozone guy from a distance and it was somewhat dark and difficult to see and so I can’t say for sure if that is how he did it. I should have paid more attention. Such a basic thing I would think even a discount auto worker wouldn’t make that mistake. They must do hundreds and he sure talked like he knew what he was doing
. On the other hand, today I reset the battery because it was seated on top of the tray and the cable on the negative post wasn’t fully seated. Hmmmm.
Thanks again to both of you. I appreciate the help!
