    Wrangler won't start dash beeps and gauges flicker

    Needing some help. Went to start my 02 wrangler X this morning and I had nothing not even Odometer reading. Take the key out and the dash starts beeping and gauges are jumping up and down. Jump started it this morning drove to work got there and it was completely dead again. Tried to jump it again and all accessories worked fine but wouldn't turn over fast enough to start. Started for a minute once but died out after taking my foot off the gas. What could be the cause? What is the beeping?

    Battery terminal clamps good and tight? Oxidation at the terminals?

    Do you have the black key or the grey one? It may be a sensorkey (security system) issue.

    On my way to a local football game yesterday and exact same scenario happend to me. Put in the key nothing. On turning it off all the guages start jumping in tandem on some sort of pulse. No starter no spark. Anyone figure out what this might be or am I to spend today one starting component at a time. Any hints or info to cut down on my investigating time would be really welcome today.

    as stated above, check your battery terminals. just because they look tight and clean doesnt mean they are. give them both a twist and see what happens.

    Same thing was happening to me. My friends jeep did the exact thing too. Underneath the battery tray I had a dead short caused from the Battery temperature sensor. I had bare wire touching and I think it was screwing up the connections. I repaired it but the other thing I did was take a wire brush to the terminals. After wards it started fine so it might not be that wire. Anyway I would check all that out. I replaced the terminals on mine also because they looked a little corroded.

    A bad battery will cause your jeep to become possessed with electrical demons . Synchronized flickering, beeping, relays clicking and jumping guages are a symptom. The battery could be in it's final death throes.

    I suggest that you get the battery tested.
