possibly a car alarm does ur zed hav a car alarm installed, because what can happen the car alarm, if its faulty will draw way too much power as its active whilst the car is off, thus causin ur battery to go flat (This happened to my zed, so im talking from experieince)
Kills the battery Unless your battery is a deep discharge battery every time it goes flat is not good for it. What you need is a cheap multimeter hooked up to measure current (Amps). Then (car off) pop out a fuse and touch each terminal of where the fuse was with each of the probes. If the meter registers any amps then theres your problem. You will need to read the wiring diagrams to see what circuits that fuse powers up so where to look. Installed accessories will make more difficult because theyre not on the nissan wiring diagram try to remove them if its easy to.
Woah thats really lazy of you... people goto the time to help you. and you spit it back saying, to much effort!!!! :bash: :bash: Edit: and what yeti said i'd do that as its least amount of effort.. $10 for multimeter at dicksmith and quick google search of wiring diagram..
Check the suspects first I bet there are circuits you suspect. Check them first. The wiring diagram in the online manual is a little daunting until you realise it shows all options. Your car wont have most of the euro stuff fitted like wing mirror demisters/ extra headlamp units/ etc. Remember some aftermarket stuff like amplifiers will be hooked up direct to the battery with its own fuse. It will be a fun litle easter egg hunt for you.
well i fixed the accesory thing...turns out my lil midget freind(his about 140 sumthing cm's high) that i sent under my dash to look at the fuses coz i couldnt really fit....dosent no how to check fuses properly he said he checked them all but obviously he didnt coz the 1st fuse i pulld out was gonnneeeskies ....replaced it...all fixed battery seems to b holding itself now aswell...so may of been the headunit draining it
Sorry to dig up an old thread but i figure if i made a new one ill just get flamed. My battery is going flat heaps too and my question's where: What kind of drainage would and amp and a sub pull being permanently hooked up to the battery, but with the amp on a switch that i turn off? and Does a ZID system drain battery? its the only thing i notice that stays on.
The amp wouldn't use any power if it's remotely switched and your switch is off... unless there's a short somewhere leaking current or the amp itself is faulty. Haven't used a ZID but if it has a little LED then that only uses milliamps of current so that wouldn't be anything to worry about either. I'd say there's a short somewhere
Nothing... [/quote]Does a ZID system drain battery? its the only thing i notice that stays on.[/QUOTE] Don't know how they work so I can't answer your question, but I can confidently say that it wouldn't be enough to drain a battery. You need to go to tech section, type "batteries" into the search function and read my article. It will tell you everything you need to know to diagnose a faulty battery.
my battery was going dead from only running the car once / week, I suspected something was draining too much power but a multimeter showed 20mA which isn't a lot, was just the battery on its way out.
yer i might get a new one, mine's fairly old, i dont really trust it. and id hate to have to push the Z, they dont roll at all.
Charged it all day, got in it to start it and it didnt even have enugh grunt to fully illuminate the dash. Looks like im getting a new one dono how I'm getting to work though...
There's your problem...someone's stealing the power from your battery and there's no alarm to warn you! Seriously though, it's one of 2 things. Either the alternator isn't pushing enough current to run your electrics and charge your battery sufficiently, or you have a significant current drain from a faulty piece of hardware. When I say faulty it may not appear to be faulty, it may work fine, but it is draining current. Your stereo pulls a minute amount of power to keep your memory settings, your amp (if you have one) has a constant power supply and so does your ecu. Any one of these could be draining the battery without you being aware of it. But it sounds like an alternator on the way out to me.
collapsed battery cores, doesn't matter how charged it is - it looses charge in a matter of hours. very common, new batt should hopefully fix.
Getting one this afternoon, so ill let yas know tomorrow sometime how it all goes, if it still drains ill prolly just cry.
I had teh same problem and it turned out to be my alarm system. Replaced it and car was as good as gold. Take it to an auto electrician and they should be able to confirm.
