C5 2009 Tourer No Power To Rear 12V Socket And Tail Lift

[Chrisc5v6]

(Still think it might be a broken wire in the loom supplying the tailgate.)

 

You may well be correct as that's why the doors lock as they think the tailgate is shut and its not ,next job.

 

Paul

The fuses seem to be readily available.

I was going to buy a new a battery on my three year anniversary  so I will change it when I get a new battery As you point out it could be well old

I wasn't going to mention the wires as the wire colour to the fuse is blue and not the expected pink so it must go through something else.(Hey ho) 

 

The fuse blew because I blew it with a crap extension socket from a cheap shop. 

(idiot, still I now know a bit about the car )

I bought 2 fuses and sat there looking at them so a complete change of plan I went out and fitted the fuse 

Disconnected the battery and changed the fuse not so easy with the battery in position but accheivable .

And now the 12v socket works as it should and the offending socket from the cheap shop is long gone.

However 

I did rather think that there was a connection between the fuse and the tailgate raise and lower 

there is not as that still dosnt work .

Back to the manual .

regard

the auto locking with the tail gate open very strange indeed with the tailgate open the auto locks works within 30 secs

with the tail gate shut the auto doesn't work ever.

Does the car think the tail gate is open when it is closed - any messages on the dash ? If it did though the car would not lock. You could try with the tail gate open but close its lock against a screwdriver if you want to do any tests. I think the car gets its door open/closed info from switches built in to the locks. I would also have a good look at the tail gate wiring where it goes between the body/door in the rubber sleeve since it is common for the wires to break. If there is not a fault then maybe it is a software problem that might need an update.

 

You have still not mentioned if you have measured the battery voltage or tried the tail gate opening with the engine running.

[Chrisc5v6]

The voltage first thing this morning was 12.03 volts.

Once started it went to 14.06 volts

and no the tail lift dosnt work with the engine running.

 

I checked all the wires leaving the door they appear to be intact 

 

I need to do some comprehension on a total reset and what happens when I disconnect the battery for a long time.

12.03 volts is low, is it turning over slowly on the starter ? You could do with giving the battery a charge disconnected from the car and then seeing what happens. A full charge should be about 12.7 volts and anything less than about 12.3 volts is low. 14.06 volts also seems a bit low, are you measuring the voltage on the battery ?

[Chrisc5v6]

I used a multimeter on the battery in the rear and I have a plug in one for the cigarette lighter plug that gives a readout as I'm driving

The battery fitted to my car is on the small size for such a large size ,I'm assured its correct for the car.

I don't use my car in the week so it sits all week until Saturday when it starts first time even in the winter.

 

Now battery manufacturers say that a sealed battery dosnt need any maintenance ,but that isn't true is it battery manufactures as the electrolyte evaporates and part

of the plates become uncovered and then a battery doesn't perform very well .if you are able get the plugs out you can top up the electrolyte and fill up with distilled water and a good charge and it will last a little longer .

 

So I shall bite the bullet and take it out and check it and apply the above

Else

I could dig in my pocket and buy one for £85 locally.

 

What I don't know is what will I do to any settings in the car if any .

Or will t,here be a complete reset and miraculously all faults vanish.

Yes I believe in fairies.

I check mine and top up with melted ice from the freezer about every couple of months. Have to be a bit brutal with a wide tipped screwdriver to unscrew the (filler) plugs!

My first ( from new) battery lasted about 9 years before a cell went.

Charging the battery produces hydrogen and oxygen frmo the water in the electrolyte, thus the level gets lower.

I keep meaning to watch one of those revive any battery videos but there full of such padding I get bored with it the bit you want to hear is right at the end.why pad it with such dross

Has. Anyone actually got to the end of one

But I think all its to tell you is put Epsom salts in there to revive your battery

But I've found over the years distilled wAter works fine

You should not lose any settings other than the date/time when you disconnect the battery, provided you let the bsi shut down. Post 7 has the procedure I use and there is probably something in your handbook.

 

I am servicing our C3 this week and checked the battery at the battery terminals. Was about 12.6 volts when the bsi was not doing anything, then after opening a door and not giving the bsi time to shut down it dropped to about 12.4 volts. With the engine running it was about 13 volts so the alternator might be one that can vary its output so I might do some more checks later. So the old expectation of about 14.4 volts with the engine running might not apply on newer cars.

yes I have printed it out so I can follow step by step  I will give it a go next week maybe Monday, thanks again

nothing ventured nothing gained

if it aint broke don't fix it

how many posts before I can add an icon picture

Edited August 8, 2017 by Chrisc5v6

[paul.h]

You can add an icon any time but there seems to be a problem adding icon pictures (avatars), some people have been able to put one on, others not. It needs admin to do a fix but he has not been on the site since last September. There are other problems that need fixing as well, I had to change my email address but it sent a validating one to my old address which no longer exists so I am now validating. Fortunately it has not stopped me doing things on the site as a new member would find.

Well I bit the bullet and disconnected the battery and put a charger on it with a meter to tell what was going on, the battery started at 2.5 amps and fell away to 1.8 in an hours charge.

After the hour I put it back and everything seemed ok.... apart from the door locking which stayed the same.

Which is .....

with all doors shut... no auto locking

with the tail gate open auto locking with 30 secs

it would seem that the only thing that was affected by the disconnect was the clock, the radio still worked and more importantly so did the car,

In the coming months I may well save up the £65 and buy a new battery.

[paul.h]

If it only took an hour to charge the battery back to about 12.7 volts then that is a sign of one down on capacity. I would have thought it needs half a day to charge from about 12.03 volts. At least you now know how to fix the tailgate opening when funds allow.
