6G Celicas Forums

For some reason my celica always seems to drain my battery when I park it and dont use it overnight. After a jump it fires right up and have no further issues. What I have done when its completely dead I jump start it, drive it for like an hour and let the alternator charge the battery up. When I go to park it overnight, I remove the main 60A fuse in the engine bay and leave it like that. The next day It fires right up no problems, but if I leave the fuse in place next morning, starter just starts clikkkin, cant even crank the car. I have looked for something thats draining the power but cant find anything, I dont even have a stereo in place. Any help appreicated.

how old is you battery?

take your car battery to be charged and tested at any auto parts store. its free and can save you some head aches. simple as that.

Its really not that old, I would say about or a little less than a year old. I was running it on my other car (Infiniti Q45) and didnt have any problems ever. Well except one time it did die out on the Infiniti but after that I never had a problem, even playing the stereo for hours it would turn on no hesitation.

So you guys think its the battery?? Ill try that to get it tested, maybe it purchase a new one next weekend, but i have feeling something is draining it.

Make sure and get your battery tested before you go and buy a new one.

make sure your cables are tight mine were loose and it didnt start chek your hook ups.

It's your battery. Brand name does make a difference.

Random is right... brand name batteries are usually known to provide better quality. But that is simple logic (you get what you pay for)

on another note. its not always the battery.
- check if you have any aftermarket hookups examples of. LED wiring, amp wiring, like sources that could draw from the battery.
- if you do, disconnect them, one day at a time to see if your battery is drain the next day.
***example: if you have a led wiring hookup, disconnect it. anf if your battery is fine the next day. you know its your led right? ***
(i once had a power draw from the on/off switch of a glow gauge set)
- check for any burnt bulbs, rarely but sometimes they can still draw small amounts of power
- you might have a bad relay somewhere in the car (a big pain in the you know what but its happen to me before)

hope this helps, good luck.

Thats exactly what I think it is, something is wired to constantly pull current from the battery. I got the battery charged and tested and it works fine. Left overnight, next day its dead. UGH!

Anyways jump started again drove it around and the battery is holding a charge. I remove the main 60AMP fuse, left it overnight. Put fuse back in, starts right up.

I see an alarm siren in the engine bay so im going to try and find where it leads to or at least test it with a multimeter. Dont see any LEDs or anything like that, other than that security red LED. Guess im gonna have to get dirty tomorrow and try to find this mysterious power draw.

step one is to test it. autozone, napa, o'riley, and advanced will do it free... FREE!!!

step two is to post your results.

now; i'll tell you like i told my ex... "get tested then we'll talk"

I lol'd.

It doesn't sound like a battery but a parasitic drain. Do you have a dvom? If so you have to go through and pull every fuse while monitoring the amps being drawn until you isolate the problem. You could get a battery capacity test done but from what you have described you will be wasting money on a new battery.

if you say your battery and your alternator is good. something is drawing from it, do you have an amp that is running without a working remote? anything directly connected to the battery?

What is a "dvom?" SO test every slot in the fuse box and find one thats pulling current? I can test it with a multimeter and see how much volts its drawing or amps.



I actually dont have any type of stereo hooked up, well i do have a deck wired in but the faceplate is removed and no speakers are wired. I guess ill remove it tomorrow and see the results.

you can tell if your player is not using a remote, try turning it on without putting in the key.

get a multi meter and take the neg or positive calbe off and set it to measuare amps, use the multi meter as a jumper between the battery and the pos. or neg. cable. You should see a current draw, now start pulling fuses and when you pull a fuse and the current draw drops, you know that you have a parasitic drain from that specific circuit.

This. I can't remember the exact numbers, but most cars will pull a small amperage when completely off (like .5 of an amp at most). So you'll never get it to zero.

yea i realize that, the computers need power to save memory and what not. But you'll see a big difference when you pull a fuse the current will drop noticeably

I binned a 1 Farad capacitor due to this.

If I ever get another farad I will hook it onto a high power Relay.

I'm suspecting a low battery as others said but also your gen may be not charging sufficiently. Enough to not making the battery light comes on but not enough to maintain your battery. Another thing... make sure your battery light comes on when you turn the ignition, if not, remplace the bulb cuz when the bulb is blown, the gen does not recharching the battery at all, as stupid as may sound...
