  • battery voltage gauge

    so my voltage gauge keeps pegging at +19V. it does it at random times every couple of days. i have a 99Tj and was wondering if anyone else has had this problem. is it just the battery going bad or something more serious?

        yeah the rest of the gauges are fine, its just the battery gauge. i dont think its a short b/c it goes away when i shut it down and crank it back up. i am going to take it by advance auto parts and have them test it. after that i guess its on to the voltage regulator as you suggested RUBICON i just thought id see what y'all had to say. thanks.

          ok so everything tested good. i think im gonna have to take the alternator out an have it tested seperately and even then you cant trust it. ive seen so many of them go bad and test good. any other advice?

              Good point, your battery may have a bad cell, or be getting ready to go.

                  well i replaced my battery with a yellow top. still had problems. replaced the alternator with a little bit beefier one but not much. i want a mean green but this was all i could afford. anyway it was the voltage regulator in the alternator. spent more than i wanted but did get my yellow top optima.
