I have a 2007 Jeep wrangler unlimited & all of a sudden the battery died so had to get it jumpstarted then died again but now realized something is draining the battery & the headlights & backlights are on & don't want to shut off... ive messed with switch to make sure its off but there all on & the radio appearance is dim & turning signals are dim or not working... what could be the cause if anyone knows or has a this happened to anyone before thank you
well i bought from another owner and said i think it was a new battery... but i'd have to confirm but yea when i shut the car off everything shuts off but when i put the car on the lights go on without touching the switch which is weird
TJs and JKs both need the negative battery terminal disconnected for some time to reset the electronics after the battery voltage drops down low or the battery dies. Have the battery tested if it looks old.
Have the battery load tested. Also use a test meter to do a system drain check (there are instructions on JF if you're not sure how to do this) .
