cranbiz What does the light bar draw for amps? Where did you tie in for the power?

You might need a bigger alternator but for just a light bar, I'm thinking you have other issues. Start by checking for parasitic draw, lets see if you have something drawing more that it should. If you are pulling light bar power from the TIPM, move your power source.

Bad battery? HELP

I recently replaced my battery because the battery light had come on and I went to AutoZone to get the battery checked and sure enough it was bad battery but it was time for that battery to go it was the one that came with the Jeep, anyways recently I've been trailing around and night and I have to use my light bar, after a while of using the light bar the jeep starts to "run out of battery" I assume, I'm not really too sure what's wrong with it but after a while, the light bar starts strobing then it turns off and it comes back on and the battery icon shows up, while this "strobing" of the light is happening the headlights are also doing the same thing and everything that is illuminated in the jeep, kinda scary when it happens at night not gonna lie. Any idea why this is happening? When I went to AutoZone they checked the alternator and it was good. Also from time to time while I'm driving the speedometer will drop to 0 and the ABD light and the Brake light come on and the jeep makes that sound like when your fuel light comes on, the rpm needle isn't affected while this happens, but then everything comes back to normal not even a second later. I'm not sure what's wrong with my Wrangler... It's a 2017 JKU any idea what could be going on?
