As of this morning, our 13 Dart has erratic gauge movement when cranking at startup... it did this 4 concecuative time during our morning errands, but has not done it again this afternoon.

My initial thought is loose battery terminals, but I'll take any thoughts, as I need to get it sorted tomorrow.

 

let us know how you make out

 

All terminals are secure... the battery voltage is 12.45 (after sitting overnight).
It is still doing it intermittently... I did four consecutive starts this morning... first was fine, second and third it occurred, forth it was fine again.
There is no CEL or other warning of error.
Without further input, I'll have to hope nothing is seriously wrong and causing damage.
I'll make an update if a cause/fix is found, but I hope someone else here has some input.

 

Didn't start this morning, and had to jump it... load tested the battery, and it was shot.Put in a new battery and all is fine again.

I guess the factory battery is good enough to get it off the lot
Though to be fair, it did last about 18 months.

 

My car ( Dart) is doing the same exact thing. Where did you guy's get your battery? This thing is different than any one I have ever seen!!
