Hi Everyone
Well I am well and truly stumped, Cliff fitted the isolater but when he activates it the back up alarm goes off. He tried removing the alarm fuse but still the back up alarm goes. He then managed to silence the alarm but I am worried that the alarm is still active. Should the alarm still work with fuse taken out? I know when Andy had a look for me everytime he disconnected the negative the backup alarm went off. I am thinking that the alarm may be the root of the problem ie the draining. . Sorry to keep asking but Can anyone help please? Thanks Tracy

I think I remember you saying that you have the small key to turn the alarm off Tracy, so you can switch the alarm siren off.

Have read there is a backup battery in the alarm so that's why its going off with power disconnected. Turn off the alarm siren, it should discharge the battery in the alarm but as it has no power it should stop discharging the car battery if that is the cause. Hope you get it sorted asap.

Hi Guys
Thanks for getting back so quickly. Sorry for sounding stupid but we have turned off the siren box do we need to take out fuse 43 again for the alarm as well or will just turning the siren off disable the alarm.we have tried locking the car with the fob and no 43 fuse removed and the car still locks and the lights fladh as though the alatm is set. Just no sound. I think we are getting ourselves confused now. Lol Tracy

Am no expert but I'd expect the alarm and central locking to be independent. Does the car lock with the fob with the fuse 43 removed?
If so then it sounds like its just the power feed for the alarm. I'd leave the fuse out if the car still locks.

Hi Guys
Just one final question before we put the tools away for the night.
Not understanding electrics , Should the backup alatm go off when the negative terminal is disconnected. Cliff cant understand this as he thought it would not do this.
Thanks Tracy

I presume that the 12v feed has been removed because the fuse is pulled. It is possible that with no 12V input but the ground (negative) also removed that the alarm electronics inside are confused and the alarm goes off (even if you have turned it off with the key). It is possible that the alarm is getting power from one of the other sensor inputs. With the 12 feed removed by the fuse you shouldn't need to disconnect the negative (ground) side, only the fuse.

Now you've got me thinking - if the alarm is getting a power source via an input rather than its twelve volts it might just be that that is causing the battery drain. Removing the fuse and even the ground connection might still not solve the power drain if the alarm is sourcing power from another source. Only complete isolation of the alarm might solve it if that is what it is.

Hi
Thanks for the info. It does seem a bit complicated for us.
We have reconnected the battery and we have put the car back together with just the siren turned off with the key and the fuse put back in. We have locked the car without the alarm on and we will see if there is any drop in the battery tomorrow. Might need a good run tomorrow to keep it topped up.
Thanks again for your help and hopefully we will get to the bottom of it before our trips out with you guys over the next couple of months.

Hi Sorry jyst saw this reply.
Yes if we remove fuse 43 the car still locks with the fob and the lights still flash. We have finally left the car locked with no 43 removed and the siren turned off. Lets see what tomorrow brings lol
Thanks Tracy

the alarm can draw from the zke control unit. the only way forward is as Redline has described ie measure parasitic drain while removing fuses. it could be something simple like seat switch short (for some reason the passenger seats are prone to this, and as already suggested the boot light is also common, the interior lights are on a timer and will time out but the boot light is not).

This is a very obvious check, and I apologise if it sounds stupid - but as part of the process of elimination, check your interior light above your mirror is in the off position - not the timer position, and to see if it has any effect.

The interior light is in the off position we did this in the beginning of issue.
Boot light is totally removed. The alarm is never set only locked with the key the siren is turned
Off with the key.

Thank you for your input

As said i really can't go on like this anymore the cars unreliable when I need it most.
At a total loss I am not mechanically minded.
