Power is cutting out (1 Viewer)

[Steve O]

Can anyone help!! I changed my battery and now when I turn the key to start all power cuts out.
I have to open hood remove the negative side of battery for a few seconds put it back on and push the unlock buttton on key fob. I checked fuses and they seem to ok. Most of the time it works sometimes it takes a few tries. Changed the battery on key fob too.
Not sure what the problem is. Really annoying when going to car wash.
Does anyone know what is going on?
Thanks

Sounds like a loose terminal or bad ground

Thanks I’ll upgrade my ground and see if that helps

Also check the connection between the positive and the small fuse block behind the battery. Look at the bottom side for corrosion.

Will do thanks Dwight!

Checked out the positive side, very little corrosion, but will clean up anyways. Looking at the ground, wire is a little loose (have new terminal on the way). Also noticed some swelling on ground wire under insulation just after terminal, can’t cut because it’s too short. I would like to replace but can’t see where it goes yet. How long is ground wire? Where does it lead to? What size is it? (#2 or 1 I think) Should replace with same size?
