Clicking relay, jeep totally dead

Need some help please.

I went to home depot yesterday. Got home... Unloaded some things cleaned up outside from my project, and when I went to back the Jeep into the garage, it was totally dead. About 1.5 hrs from the last start.

There is a constant clicking sound coming from 3 relays: K1 run/accy relay, K2 run relay, and K4 run/start relay. The dash light flash some then stop. The ignition is completely unresponsive. I tried to jump start it but nothing. It would not even turn over. It's like the electrical has gone complete haywire.

The key is out of the ignition and the clicking doesn't let up. I can hear and feel them clicking non stop. I popped the relays out and back in... nothing.

I have a 2012 JKU with ~15k miles. I'll have to tow it into the dealer and miss work if I can't get it fixed.

Any suggestions for getting it started?

Unhook the battery for about 20 minutes or so, see if that helps. If it does, make sure you take in anyway and make them check it over.

Thanks. Unfortunately I got your message too late. Toe truck is on the way and I'm off in my wife's car. She isn't going into the office today so it's working out alright I suppose.

It's the battery. Atleast when my 08 did that exact thing the battery was toast. I've had a lot of dead batteries but I had never seen a vehicle flicker and click like that. Kinda freaked me out.

I don't think so. Not the same kind of clicking. Plus, I tried to jump start it. The ignition was completely unresponsive even after sitting in the driveway hooked up for 5 min.

This weird electrical clicking coming from the fuse box even when the key is out. Not when you're trying to start the engine.

I didn't mean to sound so certain. But that's exactly what mine did when the battery was done. I called my uncle who's an expert mechanic/garage owner and he said it was probably the battery. I didn't believe him because I tried to jump it off and got nothing. I could hear the relays clicking away and had flashing lights on the dash but the key was in my pocket. I thought something was shorting out. I tried resetting it and eventually took the battery to get tested (it was bad). Popped in a new battery and all was/is good.

I'm not saying that's definitely what ia wrong with your but what you're describing is how I described the problem over the phone. He said that some newer cars do bizarre things like that when the battery gets low or is bad.
Well I just wanted to share my experience with a similar malfunction. Good luck with your ride.

Well.... You were RIGHT!! Lol. I can't believe it. Is WAS a bad battery. It was probably actually a faulty battery. There's no reason why it should have gone "bad" that quickly.

As for the flashing of light and of the instrument panel, and the run/start relays, when the voltage gets below 9.5 V, there are low voltage systems that go haywire.

I actually had a difficult time believing them, but they assured me that was the case.

So I got a new battery. We'll see how it goes.

They also said that they have had lots of dead batteries on the lot recently. They said the heat has caused a number of them to fail.

Does Chrysler just use cheap batteries? I've NEVER had a battery fail like that. 15k miles... 9 months old....

Just wanted to say thanks guys! I had the same problem and thought nah, couldn't be the battery. So I put the tester on and it showed full. When I went to double check again I tested on the terminal clamps instead of the battery terminal itself and saw only 2v getting through, so I knew the problem instantly, there was a heap of corrosion on the terminal clamps when I took them off, so cleaned up and hooked that back up and away she went.

Thanks again!

This thread caught my interest.

My 08 X has a relay that clicks every 20 seconds or so when in accessory mode but not when the ignition is off or the vehicle is running. Different than what everyone is discussing but then again this has given me some ideas on addressing the issue particularly the battery posts. Anyone else heard of this?

Thx
