2005 Dodge Caravan JUST went dead. No apparent corrosion on battery posts or cables. Dashboard needles wiggle, dash lights come on or flicker when key turned on. Sometimes a clicking when key turned over.

It sounds like you just have a defective battery, new sealed batteries do this exact thing. I have had this happen on my personnel cars and trucks about 5 times over the years. Also make sure the battery cable are clean and free of corrosion.

Could be a bad battery but I suspect your battery cable is either loose or corroded or dirty. Before you pull the battery disconnect your battery cables and clean them both ends and when you put them back on make sure you have good connections and tighten good.If that does not work pull your battery and get it tested at a battery out let . they should do that for free.

it is the immobilizer indicator ( red light far right hand corner of dash) it usally means that key is not communicating with computer , try another key ? or if your battery went dead this could cause communacation failure? check your ground to battery and then leave battery disconnected for a few hours , and if there is someone who can scan for codes and wright down any that are there and then clear codes, it can also just be a computer failure that has triggered that light.

Had the same problem last year. It was the first time in my life that I ever saw a dashboard go haywire, like you describe. Turns out it was just a dead battery. Replaced it; no problems since.

if battery is not holding or getting a charge check this out. jump start car, read voltage at battery posts. if it is charging it will read from 14.2-14.7, if its charging ok and still not enough power to turn it over. then you have a bad battery. check belt to alternator first for tightness. good-day! if battery is charging at battery car off , there should be at least 12.6 volts all accessories off. make sure battery post clamps are clean and tight. what i do is put a bit of grease on the battery clamps to hinder the corrosion build up from acid ,on the posts.

Sounds like your car thinks it is being stolen-have you tried to reset the alarm with the remote? Is the alarm factory?

Have battery check at local parts store, replace if bad.

possible earth cable corrosion on the connection point to the chassis ,now where this is ?? i dont know but it has to be either under the dash on in the centre column bit above the radio

loose battery connections or bad ground connection

Like you said, battery may be flat. You can check that with a multimeter.

Next check the alternator. Faulty alternator leads to uncharged battery.
