I went to Advance Auto to replace the original battery on my 2011 Nissan Frontier SV 4 wd v6. They plugged in a box into the OBI 2 port. Changed the battery but the positive wasn't tight and when we went to check it pinged and wouldn't start. He took off the positive and retightened. The truck started, but the blower motor was on full and couldn't be controlled. The gauges do not initially work well but after a few seconds they work. Also some small things didn't work, open door alarm, ect. They then changed the fusible link on the positive cable, no change. If you use the power pack on the OBD2 port everything works fine. Remove it and the problems show. What could be the problem? - fuse somewhere to OBD2 port? Looked at all 3 fuse box locations and they seemed fine.

If the post won’t clamp tightly they sell shim caps to fill the void. If all was well before the battery change why would something else other than battery or loose cables be the culprit?
I’d use a continuity tester on a fuse as it may look ok but no be ok.
Welcome to the forum and hope you get it figured out. There are places under the hood as well as in the passenger compartment with fuses and relays, good luck.

I've been noticing that a lot, lately, on batteries made by Johnson Controls. I'm not sure what the deal is with the skinnier battery posts, but I sure wish they'd go back to the old style!

Well, Johnson Controls makes most of the automotive batteries sold in the USA. Figure that reduced size (reduced lead) in posts is a cost savings project, pretty much all companies these days look for ways to save a nickel.
I'd disconnect battery completely, clear the ECU memory, then re-attach the cables.

Did they check the battery charge before they gave it to you ? Did they do a load test as well? If Johnson Controls makes a lot of batterys like Cusser said, you could easily get an under charged or defective battery. Due to the huge volume they manufacture and the amount of batterys being sold by parts stores this time of year, some slip past. If you didnt watch them do the tests, I would take it back and ask them to check it out. This will cost you nothing but gas and you have to verify the battery condition before you buy anything else.
