Won't turn over after working perfectly yesterday???
 

Truck's been runnin great lately and I get in to go today and it just gives me a clicking noise under the hood. Acts like it did after I had te battery unhooked but I haven't touched the battery... Had to take the car so I haven't had a chance to try anything yet

As picky as these trucks seem to be with cables and whatnot, I'd start there and make double-sure they are clean and tight. If nothing is the issue there then time to check the battery voltage. Maybe something drained it?

Yeah the post clamps are kinda funky but I cleaned em as much as u could couple weeks ago and it's been fine. Everything electrical works just fine like radio, locks, windows, etc

I would get the battery checked, they can have a cell short out very quickly. If it's good, then sounds like a starter solinoid.

Yea, they'll do that when the battery drops below 12 volts. I think it's 11.8 (?). Once it's 11.8, they just click like that.

Get the battery checked....

Fix that properly.

I'm gonna get a new battery and cables. Looks like replacing cables an be a pain? Was just gonna get new clamps but neg and pos cables have another wire attached to main cable on each side

Also, with key in ON position the ABS light and Battery light flash on/off like a steady 1sec on/ 1sec off

Go somewhere and check the battery before you buy a new one, you should still be able to start it by jumping it with another vehicle. I learned the hard way on this and replaced a perfectly good battery when it ended up my starter was bad, same thing as yours worked perfectly one day and next day all it did was click.

Well the post clamp DEFINITELY needs replaced or cleaned somehow. Got quite a bit corroded since I cleaned it bout 2.5 weeks ago

You should be able to buy new post at autozone, they normally just thread in just be careful not to strip it. As for cleaning iirc diet pepsi seems to work wonders pulling of the build up on them.

The clamps can be cleaned that way? What about baking soda solution or somethin to dissolve the corrosion?

I think he thought you had broken a post and you are referring to the cable ends. You can use a wire brush. They even make them specically for this purpose.

I'm well aware of the brushes and have already used them. However, I cannot get all of the corrosion off of the clamp that is why I asked about dissolving corrosion that is adhered to the clamp
