Wrench Set, Socket Set, Wire Strippers, MultimeterAfter having battery issues with my 2020 Jeep Gladiator Rubicon, I did a little research to see if I could pinpoint the problem. From what I can gather, the smaller auxiliary battery had gone bad and was brining down my main battery.
Since I used the Tazer to keep the auto stop-start feature disabled on my JT, it stood to reason that I should be able to bypass the smaller battery altogether. So, that's exactly what I did with great results.
