ONCEBITN Posted June 30, 2014 Author Share Posted June 30, 2014 cleaned battery today, checked fuse and checked volt output of alternator its steedy at 12.2 Link to comment Share on other sites More sharing options...
Slartibartfast Posted July 1, 2014 Share Posted July 1, 2014 12.2 is low. Those lights sound like alternator trouble, but you may have just run the battery down by leaving the code scanner in all night. I'd let it idle (or drive around a bit, somewhere you won't die if the battery does) and see if the voltage comes back up/warning lights go out.

FeelthePathos95 Posted July 1, 2014 Share Posted July 1, 2014 If it's the alternator you won't get far before the truck dies. I'd just find the time to run it around your neighborhood for awhile. You charge the battery if that's all you need and are close to home if you've got worse problems. Sure the people on your block might think you're crazy for driving in circles, but at least you can pull it to the curb and walk back to your place to wait for a tow rather than be stuck somewhere you don't want to be. If I sound like the voice of experience when it comes to having a Pathfinder with a dying alternator it's because I've been there. Link to comment Share on other sites More sharing options...
adamzan Posted July 2, 2014 Share Posted July 2, 2014 12.2 is way too low. It should be at least above 13, and ideally near 14. Link to comment Share on other sites More sharing options...
devonianwalk Posted July 2, 2014 Share Posted July 2, 2014 Dash lights staying on? Low voltage output? These are typical signs of an alternator about to die. Link to comment Share on other sites More sharing options...

devonianwalk Posted July 3, 2014 Share Posted July 3, 2014 Battery probably went first and the alty killed itself trying to keep everything going. Link to comment Share on other sites More sharing options...
