Zo6 lost all power


Hi, my 2006 zo6. Came to start it the other day and no power at all. Had it on trickle charge. Full charge and still nothing. Put some jump leads on it and nothing. All it does when you push start it make some weird crackle noise. Not a clicking, more of a faint Crackle.

Anyone had this happen before? What should I try?
Thank you.

Oh dear. Sorry to hear this.

Have you tried doing an OBD diagnostic to see what fault codes are reported? This is easy to do on the instrument cluster of a C5, but I believe not so easy on a C6.

Other than that, I'm struggling to give a good suggestion for the "weird crackle noise" you experience. Is this lack of fuel or lack of spark, I'm not so sure.

First suggestion with these cars is usually to make sure your electrical system is tip/top. Sounds like you may have had a low battery, so although you recently charged, is it giving a strong enough voltage? Is it above 12.6V after a short rest period from charging, and with everything off. Also check condition of earthing.

Could still be battery.. How do you know the battery's taking a full charge?

A flat battery can still show a decent voltage yet be totally gutless and collapse when you try to use it and be so empty that it sucks all the energy from the jump start battery.

If you try jumping it again, disconnect your own battery first and make sure the jumper battery is well connected. Keep an eye on the cables and if it still doesn't crank and they get hot, stop as you have a problem elsewhere.

Good luck..

Re: Zo6 lost all power


How old is the battery?/Is the car used regularly, and put on trickle charger/conditioner when not?

What car/battery (CCA rating?) did you attempt to jump start it with (without success)? If it was from the missuses Peugeot 206, that may not have enough juice/CCA to turn it over/start it.

When my Optima red top gave up the ghost a few months back, my portable battery back, which will jump start most things, didn't have enough juice to turn over/start the C6.

Presuming also that when you tried to jump start it, you connected up as per the handbook instructions (one of the leads attaches to the fuse box connection)?

Re: Zo6 lost all power


Hi cheers for the help!
Iíve left the battery on trickle for 24hrs.
Someone pinched my multi meter so canít chec the voltage.
Connected the jump lead like in the manual to my Audi Q7.
Left running for a while but still nothing. Fob wonít even unlock the car.
Car only used at weekends really.
Maybe a new battery?

New battery. If the fobs aren't working either then get s new battery.

Re: Zo6 lost all power


The doors won't unlock/lock using the fob(s)?. So presume also, the door(s) won't open manually either, and if they do, the interior lights are faint or non-existant? If they don't open, you have used the emergency key in the rear hatch and emergency pull to open the door?

Sounds like the battery has given up, as mine did a few months back (and your trickle charger is giving false readings?). It will make the "crackle noise," if there is a bit of activity from the battery, but not enough to turn the engine over.

As Gixer says, new battery from Tayna sounds in order. If you buy an Optima Red Top, don't discard the red plastic tray on the bottom. It's not packing/goes in the battery tray in the car.

Re: Zo6 lost all power


Ordered a new battery. Same as whatís in ther - optima red top.

Tried to start it holding multimeter accross the battery. 12.4V. And didnít drop much at all when tried to start.

Opened up the bonnet while my mate pressed start and heard a clicking noise. From around the fuse box area...

Anyway ordered new battery so will try that first! Thanks

Re: Zo6 lost all power


It could be the connection to the starter as well.
If thats bad it usually stops it starting and gives loads of gremlins as well.
Does sound like a dead battery though.
I have steered away from Optima now. Have had a re and a yellow top in mine.
1 year warranty sucks, have a Yuasa from Halfords, cheaper than Optima and
5 year warranty.

Almost certainly just needs a new battery. Red top Optimas may not like regular discharge cycles tho. i.e not using for long periods. Better to keep on a trickle charger probably.

Yellow top may be more tolerant of long periods of no use, and may recover better when re-charging from flat. This is a deep cycle battery.
