2005 Explorer won’t start has new battery

[Jpaul]

my Colored lost battery power a couple weeks ago. Got it jumped and headed to autozone. They said the alternator was good but battery wasn’t so got a new battery. But now it’s doing it again! Won’t atart just clicks but everything else will stay on. And when I turn the key into the off position everything bottoms out and starts spazzing and making a clicking noise for a few seconds and then stops. What is it

If the new battery tests OK, check cables and connections thoroughly, especially grounds to the battery and starter.

I agree. Highly likely this is a terminal or cable problem judging from the symptoms.
