Hello, fellow Tj Owners.
I have had this issue for around 4 months now.
Every so often My battery gauge will drop to the 1-4 mark and my check gauge light will go on. I pulled the code with the key jingle.
I have taken it into a battery store and autozone and they don't pull any codes and alternator and battery test fine. It starts like a dream every day and never hesitates.
I have no idea what to do before I take it into the stealership
Any help would be greatly appreciative.
I have checked all connections, cleaned all cables of dust. I have some corrosion on the cables, but that is about it. About 3 months ago I replaced the battery since the battery has been in since 2005, and put in a new stereo and want to fix this before upgrading the stereo more.
