Hello Cherokee Fam!

Seems like I can't catch a break! Went to start up the JEEP for work, no lights or anything! I have a new 150$ battery in it as well...

I have a remanned motor with only 2K on it so far, mostly new accessories including starter so I don't assume it was that.

Anyways...I tried to charge the battery- nothing.
I tried to jump it- nothing.

Then I thought it must be a bad ground from the battery. So, with the key on, and headlights on, I went to engine bay and started wiggling all the grounds until WHAM- I HAD HEADLIGHTS ON!

So now, I got power to the vehicle, grabbed my buddy to turn the key for me, and watched as it instantly fired up...

I need your opinion based on a couple pictures. Is this the reason it didn't start? Does that little bit of corrosion look bad? All I did was shake the negative a smidge...

 

I'd absolutely clean those connections up. If you see that much green, its probably worse inside the wire itself. If you've got enough play in it, hack a couple inches off and see what you have when you strip it. Otherwise, it might be time to replace them.

 

It's just grounded wire to the JEEP frame, wouldn't it be easier to replace the 4" of wire? What grade is it?

Can I pick it up at local hardware store ( assuming AZ and NAPA charge out the *** for a cut wire..)
