Help! Won't start

This is weird. I looked at my battery posts and saw that the negative was fairly corroded again. I started to loosen it, but then decided to go and get some stuff to clean it better and tightened it back up. Now when I try to start it, it doesn't turn over at all. Everything that uses electricity goes black, and the rear door hatch starts clicking for a few minutes. Disconnect the battery, and plug it back in, and everything works again until you try to start it. There is nothing extra connected, and I reset the ECU, but it still does the same thing. Any ideas

Make sure the terminals and the battery posts are well cleaned.Had a simiular problem with my '84 F-150,it turned out that the positive terminal was corroded enough to alow a small amount of power through but not enough to crank.Just because it looks clean doesn't mean it is,use a wire brush and make the posts and terminals nice and shiny then try again.

Need to get that corrosion off there. It will let everything get power, but will not let a load go through it(IE starter).

Got any baking soda? Make a paste outta it with some water and brush it on there and then rinse it all off.. Should work good as new.

just pour coke on it and let it sit for like a 30-45 secs.....and then wipe clean.....worked for me and friend to start his jeep.

Disconnected the battery and gave the terminals and cables a good scrub with the brush from a gun cleaning kit. Worked like a charm. Thanks guys.

The cable itself may be corroded internally near the clamp end, if it is, then a replacement would be the answer.

coat your terminals and connectors with dielectric grease

Had the differentials, transmission, and transfer case serviced yesterday. Had them spray both of the terminals down, thoroughly cleaned, and coated while it was being serviced. I also replaced the bolt for the negative terminal because it was corroded enough that it broke in half.

Depends. I just had this service done at the Valvoline around the corner from the office. Should have seen them all over it. Get the same reaction every place I take it. I've been to the dealer on Nicholasville Rd to do the PCM and keys. I got the Libby at Freedom on New Circle. Towery on Nicholasville Rd does my tires. Rusty at Cottman Transmission does my transmission and differential work. I've done tuning and dyno testing at Fast Enough and SR Racing. The nitrous and hood were done at Profinish-Proglass. The heads were machined in North Carolina. There's other things, plus what I've done myself.

I had to clean my battery a couple of times but been busy working on my cherokee then yesterday it would not start even after brushing the stuff off so had it checked and it was only drawing 8 volts instead of 13 otherwise too weak so I went and got the interstate megatron. I wished my liberty would have a gage like my cherokee that would show me if the power is weaking before its too late.
