Battery... replacement & diagnosis
Discussion
New Noble owner.. Flat Battery, managed to get a jump lead on the positive, earth to the engine and all comes to life...
but...
1 - I think the immobiliser is now stuck on.. how do I reset this. All the lights come on but starter button does NOTHING!
2 - If the car did start then how on earth do I take the red jump lead off without losing an arm?
3 - Does anyone have a guide / link for changing the battery, I've read that from underneath is the only way.
Desperately want the Nob up and running for the weekend, and if anyone is in the Bagshot, Surrey area let me know!
Cheers,
B 6REY

its better to have two of ya. jack it up take wheel of and side pannel. (can do without moving them but makes it a bit better) ehen got bracket undone and terminals. turn 90degrees and drop it from the bottom of your car. just have to be care full taking jump leads out. but can be done hope that helps grant
You can only change the battery from the bottom. You may need to roll the rear wheels on to something like a plank of wood before it's high enough to get a trolley jack under the sill. Also, be sure to position the jack in the right place; it says in the manual that you put it where you can see the line of rivets under the sill, a few inches in.
If all the lights are on when you turn the ignition on then it's not immobilised. You may have blown the starter fuse. Look down on the battery and you should see a bank of 4 or 5 fuses on the bulk head. Check all those are okay.
How do you remove the the positive jump lead once the engine is running ? I'd leave it well alone. The best bet is to charge the battery instead for a couple of hours.
When I bought mine, I had the same thing, after about 2 days the battery went flat and even after a charge it was flat again in a very short space of time. Best bet is to buy a new one, it's a type 075.

This sounds really similar to the issue I had a couple of years ago now. Battery had died, charged it back up but the car wouldn't even turn over (like the immobiliser was engaged). Turns out there are four or five fuses in the engine compartment behind the driver side wheel arch and the one that controls the starter had blown. Replaced it and bingo, started first time.but...

That's a tough one - always think the same myself TBH. I ended up buying a trickle charger to leave on overnight - it's something you can remove without having to risk any limbs.
Just to add, it's not that difficult to take a jump lead off the postive clamp - I have to do it all the time!
Also changing the battery is a bit of a fiddle but you can do it on your own, and I am a complete DIY luddite.
Might be worth investing in a battery doctor - which monitors the charge until it drops to a certain level at which point it cuts the power so that the battery does not drain any further.

Noddy Guide....
I basically bought a marine grade/waterproof socket and adapter off eBay (£10 ish and from Towzatronic). Drilled and filed a big hole in the rear clam (but in an area where you can't really see it when not in use). Easy to get a drill in and far enough away from the intercooler to merrily file away. Ran a fused and shielded 2 core loom from the battery terminals to the socket - this can be done from above without removing the battery.
Bought a battery conditioner/charger and cut off the supplied connector and replaced with the new adapter that plugs and locks into the socket. I had an electrical socket in the garage near the rear of the car so charger is wall mounted and I just plug it in when not in use.
Battery is always fully charged and conditioned and literally starts on the push of the button
Probably could use the existing lighter socket but I wanted a separate/direct connection to the battery and outside of the car.
Now do you want to see my clam not fastened down properly warning alarm

Me too 
.Although it might be easier, I think wheel removal is unnecessary.
Suppose it depends on your fiddliness patience factor
.In my case I would have done it slightly differently and removed the wheel arch (this will probably need to be done if checking the rear fuses anyway).

Sorry, I just repeated what you said in your earlier post didn't I?
I really should read more carefully.Edited by NobleGuy on Tuesday 21st July 12:11

so is mine and i have never once put any kind of charger near it BTW My car wouldnt start once, it would turn over but not fire, yet it jump started fine... turned out to be an ecu issue.
Dear ALL
I know this is an old post, but my battery has died and I thought I would attempt to replce it myself.
Can anybody help any further---- I've got the rear wheel off and the panel in the wheel arch ahead of that wheel. Cars jacked up and I can see where the battery must come out.
But... how the hell do you undo the nut holding the battery clamp in place or get the terminals off the old battery, and on to the new battery and re do the clamp up, and I'm assuming there is a small nut on both sides of the clamp. I can not get my arms or hands anywhere near any of it, let alone use a spanner!!
Am I missing something--I am no mechanic(in fact I wouldn't make trainee)
Any help would be much apprecaited
Thanks
