Battery isolator - drain on battery

monkeyboyv1 · Dec 8, 2012

Hi, Have been having a few issues with my zt this week.

When i park my car up for the night, and come back out the next morning, she dosen't start. Just get headlights flashing etc.

Been to garage and they have confirmed i have a drain, but its not any of the obvious issues. And have said finding the real fault could be very expensive. And advised getting a battery isolater instead.

The only thing i could link it to is a leak in my boot, which has pretty much destroyed my stereo system.

Any help much appreciated.

Well there you go. You haven't got a satnav in there as well have you. They're a classic drainer of batteries under those conditions.

Have sat nav as well. Is there any tutorials on how to disconnect the stereo, sat nav etc??

Use the Search tab (top of page). Use keywords like 'satnav disconnect' etc. It's all around somewhere. Check out the Common Problems and How To section: http://forums.mg-rover.org/showthread.php?t=160038
or for an easier job, visit the other channel where searching is more manageable.

Hmm! Misdiagnosis.

ANY garage should be able to link the fact that you have a boot full of water & the fact that there are going to be two computer based modules below the water line at some point, along with another in the side trim that has also probably been soaked.

If you disconnect all the modules in the boot I suspect that your battery drain will go away.

It needs to be sorted by someone who knows what they are doing.

Regards, Rob.
