My fitbit charge gets stuck on the finishing up step.

the battery is dead
cures

1. charge the battery using a battery charger
2. or the 4 ends of battery cable loose or rusty clean them.
3. alternator dead or its wires busted/loose or fuse blow to it
4. jumper cable crank it off 2nd car, or call AAA tow for a JUMP.
5. check ALL FUSES, skip none.
6. borrow a charged battery?
7. then scan the PCM once battery reads about 12.6vdc rested.
8. 10vdc at battery is hard fail or less. all brains go mad. this.
9. I bet you made the alternator die but is easy fix. if did. fuse blow to ALT. never do fender work near any alternator unless battery Neg lug is pulled all shops know that, and do not let them weld on your car ever unless you ask how first or boom happens and thin wallet next.

very easy just go to reliable-store it has all manuals
there many other websites also but in this matter this website is too good

Does the battery go dead over night or after sitting a couple days .

Dealer should have been able to figure this one out!

Best bet to trouble shoot is next time it is going to sit for a couple of days disconnect the battery. After the couple of days pass hook up the battery and if it's dead then the battery isn't holding a charge, if not then something in the vehicle is draining the battery.

If you live in a colder climate weak batteries tend to be more of a problem as temps get colder.

If the battery is more then 3 years old it is a prime suspect.

Hope this helps!

Better check the battery as it sure sounds like its dead. The charging system could be at fault also A brand new battery can run down and need a charge if the charging system isnt doing its job Hope this helps you .Good luck!

problem on battery light came on, loose belt tension. power is out so all part will not work. and check the battery again, make sure it was fully charge.

its your relay it keeps getting stuck change bucks for part

Your battery going dead every couple days has absolutly nothing to do with your anti-lock break module. (unless it is causing a short or something and staying on-which i doubt.) Have you ever thought that maybe the battery may be dead and old and need replacing. you should test to see how strong the battery is first with a volt meter or load tester. batterys go dead all the time- more so this time of year where it starts to get cold out. If your battery is new or just got it. (usuaslly 2 or 3 years you should be fine). - it may be your alternator isnt charging the battery anymore. Make sure all dome lights are off when the doors are closed. or that nothing else is left on

dead battery that should be charged overnight with external charger.

also check your clamps-clean and repair damaged battery terminals
