RB25det power drains ? Help.

[nismo33]

Ok... After a year of owning the car with no problems whatsoever...i have finally came across one.

Problem that i'm having is -- the battery seems to be draining heaps quickly.

i have not driven my line for 5 days... so i assumed due to the cold weather..of course we get that awful cold start..i tried starting my car-- no luck.. till it just pretty much drained the battery. ( u get that "click click click " noise everytime u turn ignition on )

so i assumed battery was dead..i had it jump started and it went ok..started.. took for a 30min drive around town.. went to the supermarket for an hour.. when i got back.. the darn thing wont kick in.-- dead battery AGAIN.. so i jump started and worked OK. -- this i assumed the battery needs replacing as i had it ever since i bought it.--- so i got me a new one.. one click and the car started.. no problem. -- now went home and tried starting the car -- 4 tries and NO LUCK.. kept trying till i hear that " click click click " noise -- battery dead again.

i dont get it.. its fine when i jump start it.. starts pretty easy... but when i leave the car off for just 2 hours..it wont start.

I ruled out the alternator coz i had that problem with my previous car and the symptoms are not the same.. the car runs well..using aircon on / stereo and head lights.. nothing i know of that signs of alternator problem.

could it be the starter motor ? :confused:

Anyone who had the same problem and would be of help would be appreciated

thanks.

If you've got a multimeter, put it in series with one of the battery leads and measure the current draw with key OFF. Should be close to 0. Anything more than 1/2 to 1.0 Amp will drain the battery pretty quick.

Is the battery voltage around 14v with the engine running?

If it jump starts OK, i'd doubt it will be the starter. Sound more like a lack of voltage problem.

[nismo33]

yes... battery voltage is at 14V when running according to my voltage meter.. dont have a multimeter though.

but what i need to know is what's causing this problem..car was fine a few days ago.. i just went away and not driven it and it went like this.

if the battery has a crook cell that would cause this, or maybe you have a dodgy terminal that by touching (during jump start) it has got it working

how old is the battery?

[SKYBEE]

if not the battery or alt try checkin if the boot light is staying on nine times out of ten boot light switches move over time and cause the dramas

[nismo33]

the battery is brand new.. just bought it 3 days ago.

will check if the boot light is staying on.

was just driving the car 2 hours ago and the darn thing wont start again.

hey does it just click or does it crank really slow??

plus double check the starter & battery terminals also you may have a volt drop on the switch wire to the starter

when you mean its flat are you sure its flat like are you head lights dim??

will your radio work??

if they do well could possible be starter related

[nismo33]

just went and check the boot light and it was fine.. doesn't stay on.-- all terminals are fine.

and yes.. i can still play the radio / stereo and some lights.. but it just wont crank up.. and when it does.. it is slow.

could be a voltage drop.. dont think its the starter as it fire up fine when hooked up to another batery.

now.. how to fix this voltage drop..??

[R31Nismoid]

if its a new battery...

it could have been sitting where u purchased it from for 2-3-4 years and could be a dud.

I've had a dud before

Buy yourself a multimeter. Dic.k Smith have a cheap 1 for less than $20. As i said earlier, check current draw with everything off. If it's OK it just about has to be the battery. Also check/clean the earth cable to the motor.
