I've got a nice new battery for my Cerb and started following the instructions in the Jools doc to replace the old one, however the alarm goes off every time the battery is disconnected for a second - which is driving my neighbours nuts.

Anyone know if you can remove a fuse to disable the alarm or similar while doing this process to stop them hating me even more?? :-)

Also - does anyone know if you need to remove the airbox pipes or whether you can just squeeze the batterty through the gap?

Many thanks in advance for any tips!

I'll answer my own questions as after searching the forums and reading (a lot!) the following seem to be valid ways of doing this.

1. Activate the alarm, disactivate the alarm, immediately disconnect battery

2. Connect portable jump start pack to positive lead as soon as disconnected to power the alarm system while removing the battery, and disarm the alarm

3. Connect jump leads from car a. to Cerb positive lead while removing the battery, and disarm the alarm

4. Remove 10Amp fuse from fuse box (the post didn't specify which one, but guessing from the black book they mean Fuse No. 8 - Injectors, alarm / immobilisers)

5. Connect portable power pack to Cerb cigarette lighter socket, and disarm the alarm [not sure weather solar trickle charger would work here - but guess not as only a trickle charger not battery - also there have been a few warnings about putting power through the cigarette socket wiring as it may not be able to take it, so guess this could be a more dangerous option)

Hope this helps other people looking for the answer!

That's a lot of work I just took the old one off (no alarm activation) put the new one in and pressed the key fob to disarm the automatic arm job done smile

Hi Dave

Yes - reading a few posts it seems some cars can just remove the battery fine, others like mine hate it and the alarm goes off like crazy!

When you say you removed the Air Box, did you just remove the silver pipe near the battery, or the black carbon fiber/metal bit of it bolted and sealed onto the engine with 6 or so bolts in it?

I didn't want to remove the black carbon fiber/metal bit as it looks like it would need resealing (= difficult) but removing the adjustable clamps on the silver pipes doesn't look too hard.

Any thoughts appreciated as I'm having another go tomorrow :-)

It sounds like you might have a different set up to me. All I had to do was undo for bolts which were holding the air box down and then move it slightly away from the wing to make enough room to get the battery in. smile

Hi Dave

Yes it does :-)

Sounds like you have an Air Box that kind of looks like this one

http://www.topgearautomotive.co.uk/images/Cerbera_...

Where as mine doesn't have any boxes, just two black 'manifolds' connected to the engine and then two big silver concertina pipes going down to the central air inlet.

Maybe it was modified at some time in the past...?

Get a set of jump leads. Connect them to the New Battery, with the other ends clamped onto the terminal ends of the cables. Now when you disconnect the old battery, the car will still have power. When you fit the new battery, just quickly connect the leads to the old battery.

OK - This didn't go as smoothly today as planned!

The battery won't slide out in the gap between the wheel arch and the air pipes, and even though I mentioned that mine just has pipes, I was actually wrong as it does have (what look like) carbon fiber boxes connected by 6 bolts to the engine manifolds on each side.

As I'm still new to this car (and everyone here definitely knows everything better than me!!) I've photographed the whole lot and would love to know if

a. I can just unbolt the pipe clamp and the 6 bolts on the carbon fiber boxes, and remove it to get the battery out, and if so what do I need to use to reseal it, as it seems to have existing sealant on there. :-)

b. what is the lose pipe in the bottom of the picture for

c. does anyone sell replacement air boxes as these ones are a bit chipped and could do with freshening up.

Many thanks!

Why is this pipe unplugged?? (the metal braided pipe, slightly rusted on the top, just before the passenger side wing)

Yes you can just unscrew the 6 bolts and and clamp to remove the air box.
Take note that there will be a small black hose connected to the back of the airbox - it goes to the baro pressure sensor.
Take care when disconnecting it as the little plastic tube it pushes on to often pulls out of the airbox.

I use self adhesive foam stip to seal the air box. Any RTV silicon will do the job but its a bit of a pig to remove them without cracking the air box.

The braided hose on the drivers side is for bleeding the clutch.

the un-plugged braided pipe is actually the bleed nipple for the clutch slave cylinder and just sorta floats around at the back there until you need it

Brilliant - thanks very much guys for the replies - would help felt a little stupid if it was something more serious, and unbolting it ruined something :-)

While I'm there I think I will replace the bolts too (they're rusty and old) - anyone know what length/thread size they are - they look M10-ish in size for the head.

Also - thanks for the tip about the Clutch Bleed pipe - I once bought a Twin Turbo charged Mitsubishi GT3000 that someone had "removed" the boost controller from on the ship over from Japan and just left the pipes disconnected from the stock boost controller.

This of course meant that the waste gates never opened, so it just boosted until it was starved of fuel = bad! Had to re-plumb the whole thing myself so learned on the job :-)

Will let you know how I get on!!

and ??????

How did you get on ??

Very interested as I am facing the problem of battery removal :thumbup@

Have sent you a mail to ask too wink

<----------------------------------------------------------------->

Well, what a star he is. He actually bothered to BB me from his holiday to give the following instructions:-

What I found worked best for me was:

- remove cover over battery and engine
- loosen clip near air box on pipe
- unblot the six bolts that connect that pipe to the engine
- loosen the nuts on the battery but do not disconnect!

Now this is the bit that really helped :-)
- disable the alarm as if you are opening the car
- quickly while the alarm is disabled unplug the battery

You should now be fine as the alarm will not go off so you can remove the battery and slide in the new one.

- connect the terminals to the new battery
- the alarm will go off so hold down the disable alarm button on the alarm remote for 5/6 seconds to re-connect it with the car
- the alarm should stop and you can now tighten the bolts and reposition battery and replace cover as before.

- you need to remove the airpipe before taking out the battery and then replace once fitted.

I used door draft sealant tape to make it air tight again as the old sealant was really cracked on mine!
