[Gazza2005au]

went down the road the other day parked me car for 1 hour went back it wouldnt start seemed asif the battery was flat the CD player keeped on resetting as if it had no power and when i turned my alarm on it would go off from low battery so 30mins later i walked home got the booster pack went back tryed to start the car it started no problems i didnt even use the booster to start it! the next morning i tryed starting the car it cranked over a few times than the battery died i used the booster pack to start it no probs she kicked over than the battery keeped on going flat the car will run once started as everything is running off the alternator so im thinking its the starter motor what do u all think it could be?

check your battery terminals, if dirty they can play up. also if it seems alright once it is warmer the battery probably needs replacing. it also could be the regulater in the altenater, they can cause the battery to drain and it may not make the light come on, try taking a terminal off the battery and let it sit overnite, if it starts next morning it will be a dud regulater

the exact things happen to mine... go to start and makes ticking noise, the cd player sounds like it is trying to reject a cd... go to jump it and starts first go... try start it an hour later and will do the same thing, ticking noise, cd player etc. i took it to an auto electrician a while ago before this starting happening and they said that the alternator is fine... load of bs. looks like its time for a new alternator and starter motor...

check your alt with a multimeter, first check how many volts in battery then start it and re-check volts. the reading should be higher. it should be about 14 volts while running. if the volts flicker up and down the regulater is stuffed.

When i got my car at first it would always run out of battery,
found out that it was my bootlight not going off, the lid simply failed to toggle the switch, had me stumped for a while.

it will stuff the battery. top the cells up with distilled water or rain water .

probbly dead battery, kmart try n auto do free bat tests,

i think mine died again... gonna have it tested tommorrow (9 months old 550CCA 11plate) its in warranty so its all good

ok, check you dont have a short, this can be done simply with a test light by disconnecting the negative terminal of the battery (ground) and connecting the test light in between the negative cable and the battery earth -. If the test light lights up (even very faintly), than there is a drain, and could even be a short, if not, than its just most probably your alternator not charging properly, and this can easily be checked at a PROPER auto electrician using a alternator tester that puts a load and checks the amp and volts simultaniously. (dont try with a multimeter, it wont be accurate enough)

Thats all i could think of
See how you go!!

PS: And some new battery's have no water in the cells at all, they are dry calcium battery's and don't ever require topping up, so make sure (if it has twist caps, than it takes water, if not, than maybe not)
