Hey guys,

Ok this is the story.

My battery keep running dead in my car.

I originally thought it was just because I dont use the car as I dont have a license so It is used once a week.

But after around 4 days it is completely dead.

Now heres the part that really trips me out like no tomorrow:

Scenario:

Jumper leads connected from a charged battery to my dead battery to try and jump it

when i remove the +ve or the -ve terminal from the charged battery my rear wiper decides to start a rotation.

It manages about half way and then when i recconect it it finishes off where it left off.

I am pretty sure this problem came with my car when i got it as this was running flat as soon as i got it.

And when i installed my stereo a headdeck, and 4 speakers ran it dead really fast when the car was off (working on it)

So i think there is something going on with the rear wiper where it is using power all the time.

I have just fully charged my battery and I am going to undo the wiring clip in the boot for the rear wiper and i will see how it goes.

If any one has any ideas let me know ..

cheers

grab a ammeter and start pulling fuses... if you are in brissy give me a ring.

hey mate i am not in brissy, im in sydney.

just subscribe to my thread and i will repost with whether or not the battery is still being drained in a few days to see if i have narrowed the problem down to the rear wiper / not.

Hopefully the battery is still fully charged, then i can somehow try to figure out how the rear wiper can be draining power the whole time while the car is off.

really it shouldnt go dead for like 2 months without use!

thanks

if you are letting it sit for THAT long remove the battery or put a trickle charger on it. the clock and radio will flatten it over that time.

I dont let it sit for that long, although I should be able to have it sit there for atleast a few weeks without having to recharge it...

ill repost in a few days and check it

A few weeks? Alarms, clock, stereo... stuff like that will all drain the battery.

My mate unplugged his battery for something like two months, and it was totally fine to start the car afterwards. If it was connected, I doubt I could still claim the same outcome.

1 week - yes. 3 weeks - you would be struggling to get it started. remove the -ve terminal if its going to sit that long.

i have the same problem.. if i don't drive my car for 24hrs .. it will go flat.. mechanic checked my battery n alternator and both was fine... i'm assuming it might be the mini piezo siren? i heard those constantly drains battery? is this correct?

  • 2 weeks later...

hey guys i had a similar prob, its all about the battery, it may not be holding its charge, because u dont drive it often... best thing to do is top it up with demineralised water charge it up and drive it regularily, or carge it and dont leave it connected in the car... as for the wiper, mine did the same thing wen the battery was almost flat, wen u kick it over it kinda moves the wiper i figured its normal...

Hey mass_iv..... so your saying its normal?

can any one explain why that is normal?

It is seriously very weird.

I have since disconnected my rear wiper connection under the boot near the speakers (brown plug) and now my battery is fine and the car turns over like its just been charged every time.

I mean i would prefer it to work with the wiper plugged in ..

i think i will plug it back in this week and check my batt voltage in a couple more days to make sure that is the problem. what you think. and maybe do what mass_iv reccomended with the battery.

hey man.. yeh just try topping the battery over and driving it around for a while... it shud work fine with the wiper plugged in.. mine does.. it only does it wen the battery is almost dead for some reason lol....

you must have something draining power continuously if the battery goes flat in a day or two.

The other thing to remember is that once a battery has been flat for a combined period of a couple of days, it is pretty much stuffed. lead acid batteries sulfate, which ruins their capacity.

thats not good to hear. my battery has been drained about 20 times :)

1st step - check to make sure nothing is staying on and draining the battery (you mentioned a stereo, have you got an amp? does it have a proper remote switch so it runs in standby mode with the car off).

2nd step - buy a new battery!! your one might not be cactus but the capacity will be a lot less. get the biggest battery you can fit if you leave your car off for long periods

3rd step - if you're not going to drive the car in more than a week or two, take the -ve terminal off the battery. then it will be at 100% charge when you go to use the car again.

    • And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!
    • And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.
    • Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).
    • You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
    • OK, so a bunch of trim needs to come off to get to the rear shock top mounts. Once the seat is out of the way, the plastic trim needs to come off. Remove 2 clips at the top then slide the trim towards the centre of the car to clear the lower clip Next you need to be able to lift the parcel shelf, which means you need to remove the mid dark trim around the door, and then the upper light trim above the parcel shelf. The mid trim has a clip in the middle to remove first, then lift the lowest trim off the top of the mid trim (unclips). At the top there is a hidden clip on the inner side to release first by pulling inwards, then the main clip releases by pulling the top towards the front of the car. The door seal comes off with the trim, just put them aside. The the lighter upper trim, this is easy to break to top clips so take it carefully. There is a hidden clip towards the bottom and another in the middle to release first by pulling inwards. Once they are out, there are 3 clips along the rear windscreen side of the panel that are hard to get under. This is what the rear of the panel looks like to assist:
