This is sort of a long story but the more you know the more you may be able to help. Last weekend I was driving my Disco up to go skiing, so far so good. We stopped at a ski shop on the way and came back out turned the key...nothing, no lights no clicks nothing. Asked for a jump, still nothing. At some point the Anti-Theft light came on but would not illuminate consistently. Every time I opened the doors, the clock would reset. Walked around town, found a portable battery charger, clipped it on the battery, instantly turned over and came to life. Problem solved for now...

Drove back down to town, M and S light started blinking and the Disco went in to limp mode, seems like a bad battery....

Got new battery, started up numerous times no problem. Figured for sure battery was the obvious issue.

Next morning go out to start her up, nothing. No lights no keyless entry, nothing. Tried jumping and I get lights and the starter will turn but ultimately turns into just clicking and all lights flashing. I'm thinking low voltage but why?

Now I notice that when I get a little juice into the battery and open the door I get a clicking from under each front seat at the wiring harness. Each time I get a click the dome lights will blink.

I have checked the battery cables, pos and neg connections and all looks well not much corrosion at all have removed and replaced the battery and everything is clean. All fuses seem to be in good order.

Any help will be much appreciated, I'm hoping its a pretty easy fix just a bad connection or ground or something but can't seem to find it.

Thanks in advance for your help.

 

there is def a problem with the electrics. First get to an autozone and have them check the battery and alternator for free. then if they both come back good you need to get a multimeter and start checking the fuse box for activity.

 

If you are getting a clicking under both front seats you could have an issue with the body control module? I know that the seats are controlled by the BCM, as well as many other items. When it is running have you noticed any other convinience items not working inside like windows...

 

Nope, before it died everything ran perfectly.

 

Like you mentioned, it sounds like a bad connection thing to me.

I had a similar issue with the "clicking" and such after replacing the battery and discovered the cables weren't fitting onto the battery tight enough, causing intermittent issues that made me think it was something else.

Try some dielectric grease on the battery terminals, this will help with the connection and also help control some of the corrosionl.

 

sounds like a similiar problem i had with my 96 trans am... i know its a totally different animal but similiar symptoms... ended up being a stuck relay in the body control modual that ran some of the antitheft and ignition key systems... either cold weather or low voltage would keep the relay from switching over completely not allowing you to start the car. you either had to let it sit and let the voltage/temp of the components crawl up a bit or have a steady 14+v's comming from a secondary source over the battery (ie. jump) to give the bcm relay enough umph to pop over.

+1 autozone to check the battery, they can do it in or out of the car, and alternator on/off the car... but battery with the cheese grater tester as we call will do a good general diagnosis of the battery voltage under load and while running, what the alternator is putting out. they also (most) have a wheel out machine thats even more extensive for testing the alt but usually just a voltmeter across the battery while its off, during starting, and while running will give enough clues to the status of each component.

 

So I took out the battery, took it to the Auto Zone to have it tested, came out good. Cleaned the heck out of all posts, cable connections, unbolted ground from block cleaned it there. Attached everything and she fired right up. Just needed a little elbow grease I guess.

Thanks to all for looking and helping!!!!

 

I had the same issue once. Those terminals are little temperamental. I love a happy ending.
