Truck won't start, good battery - no power

Holy crap! Was it under water?

 

Hi everybody

I have I think a similar problem. I've figured out it's definitely the wiring to the battery causing my truck to die. I know this because every time it dies now I move the battery a little bit and it starts right up. I know this is not going to last long.
My problem is I do not know which wire is having the issue. I do not think it is the same one mentioned above (the ground to the car).
My question is how can I narrow down which wire is causing the issue so I can replace it?

 

First: The battery should be clamped down so that it doesn't move.

The battery has two terminals going to the two post. Disconnect each of them and clean them using a battery brush on the battery post and the terminals. Once they are clean reinstall them and make sure they are tight on the posts.

** If any of this doesn't make sense you may want to get help from someone that knows something about vehicles.

 

yes, I agree I am trying to figure out a way to hold it down.

I am going to try this tomorrow pray for some luck.

 

Funny thing is I went through all this with an Optima battery a while back. Battery was 8 months old. I started by replacing ground wires, to no avail. Ended up being a junk $250 battery

 

Optima has sucked every since they got bought out. I've been using Kinetik batteries and they've been great.

 

Well... We are waiting...

 

Lol sorry for the suspense! I got a chance to wash the terminals today. I used baking soda and water mix and brushed with a toothbrush. After I reconnected the terminals tight and anchored the battery.

I think this did the trick but I'm not sure yet. I went for a long drive tried to be a little aggressive still working fine. Also before anchoring the battery I tried starting it multiple times with the battery in different positions and couldn't recreate the problem.

I'll check back in if the problem continues if not everything working fine now.

 

Another update: Everything is still working fine Cleaning the terminals did the trick.

 

I had another issue arise if you guys have any ideas I posted it here:
