about 2 weeks ago, i didnt drive the car one day, and on the next day, the battery was dead in the morning.... same thing happened today. i noticed when it started to get cold that it seemed to lack a little bit of power on start up.... but i thought that could just be the cold.

normally, id say the battery is shot, but the car is only a year and a half old.

ive had a system in the car that consists of 2 10'' subs and a 1600 watt amp. its been in the car since day 1, and no problems. im gonna start by disconnecting that....

any1 hear of simular situations or have any suggestions??

 

im betting on the battery but if the car is that new take it to the dealer

 

if you drive short distances chances are your battery is not getting its full recharge. im into my 3rd year in my original battery and it started up okay this am in about 5F temps. last time i drove it was last Tues 12/29.

 

i drive plenty distance for the alternator to charge the battery.

little update - after work it did not start (i expected that because i gave it a quick jump, drove 10 mins to work, and turned the car off) afterwards, i took it to an advanced auto shop and they tested my battery. its in perfect working order, but needs a charge. so its on a battery charger as i type.

my original guess was thats there is a short, bad ground, or something is being powered when the car is off.

i guess the alternator can be shot, but its unlikely cuz the car is only a year and a half old... its not unheard of though...

 

well if you just jump it real quick and it didnt die on you while driving then its unlikely its the alternator

 

sounds like your amp or something stereo related is not shutting off (?).

 

amp turns off when car is powered off. its all disconected, so if it has anything to do with the system, the problem will stop.

i took the car for a cruise... i didnt notice this before, but theres a indicator on the stock battery. when i put the battery back in it was at "needs charging" and after a 30 minute drive.... it was at a full charge. so that means the alternator is working!

ive got a short or something... gonna be a bitch finding it...

 

running a cap on your system? could be drawing elecricity. I say remove the fuse(s) on your stereos main power line and see if it resolves the issue. if not...grab a multimeter n get to work starting from the bat. n working your way till you find the draw :/

 

My Fit is a 2007 and I parked it on December 30th after a quick run to Wal-Mart. I did not move the car again until Monday January 4th. It
started right up even though we have had temperatures in the single
digits with wind chills temperatures near 1 degree. My car is in a garage but not heated. Never had any problems with it starting up. If you find
out what was going on let us know

Cat :x

 

Clamp on amp meter on the + post with the car running to see what your running draw is. Then turn it off and see what it's draw is. from there you can use an inline amp meter to check each circiut. More likely it's what ever has been added to the electrical system last. Good luck and keep us informed.

 

battery can be shorting internally

 

yes i am running a cap. the inline fuse is out, and im waiting till tomorrow morning to see what happens. the more i think of it, the more i feel like the cap is failing in the cold. this is the first winter the system has been in the car. i had the same system in my jeep, but a cap was definatly not needed.
so if that was the problem, ill know as soon as i startup tomorrow morning. thanks!!

 

i dont have an amp meter, but ill see if i can get a hold on one and ill do just that. thanks for your help!!!! ill keep you guys posted.

btw - nothing has been added to the car to the car in about 8 months.

 

More than likely it is the battery. Honda has replaced dozens under warranty. Have the dealer check the current available for starting. Should be 300 plus amps. CCA - cold cranking amps to battery checkers. And 300 amps (or even 150) will light you up like a Christmas tree so be careful.

Otherwise, make sure your interior and trunk lights are out when you leave your Fit.
Good luck.

 

can pick one up for $20-50(multimeter) from sears er something...nothing special but they'll get the job done n it's always nice to have around.

 

Your typical VOM won't handle 300 amps. You'll burn it up. And you too, if you are clumsy.
Best to let a parts store or dealer to check, especially dealer since its Honda warranty and the battery size is not available from Interstate, Sears etc.
I didn't find an easy replacement as the battery basket on my FIT is bigger than the Yuasa battery I didn't find a group that would fit either.

 

i had the battery tested as i already wrote and it was rated 327 out of 340 and in perfect working condition.

 

bingo!!! im about 95% sure it was the capacitor draining my battery. after disconnecting the fuse, the car started up perfect this morning. no slow start bullshit. im just gonna remove the cap, i should still have no problem powering the system without it. was a cheap one anyway, guess it bugged out in the cold. thanks for the help guys!!!!

btw - i thought this was funny. when i brought the battery in, the guy said "whats this for a motorcycle?" .... nope its for a car, lmao

 

Sorry, I missed the battery check
As for a capacitor there is no current flow unless some side circuit is involved. Whats a capacitor doing there?

 

yeah, if the capacitor is working correctly... it never really turns on or off... and if its fucked up it can very well take unnecessary power. some1 else also posted the same thing. its not digital.... so i cant tell if its holding power... but 1 thing i know is that the amp is off.
