Problem After Changing Battery

[Turbodrive]

Recently changed the battery which was starting to struggle to start the car due to colder weather (2003 1.9 TDi Ghia). However when I reattached the positive and negative leads to the new battery the car made a noise let the horn going off intermittently. It isn't the horn, as the noise is coming from under the right hand side of the dash, this only occurs when you open any door, the tailgate or the bonnet. The interior lights won't come on with the doors open but they will with the doors shut. All the central locking door relays also click intermittently when any door is opened. This has only started happening since I swapped the battery over (it is the correct battery by the way). Any advice would be greatly appreciated. Thanks.

First step disconnect it again, leave it half hour or so and try again.

 

If that doesn't work i'd check the rear hatch wiring - the righthand gaiter may well have a broken wire party going on there, causing odd behaviour with the locks.

 

it sounds to me like you've activated the test mode on the alarm - possibly by means of a broken wire shorting out rather than deliberately (the bleeps would be the sensor test).

 

It may be worth checking the rest of the doors at the same time if the boot looks ok - though I'd expect to find something wrong there if you haven't been in there already!

The alarm horn is on the bulkhead behind the wiper linkage.

Sorted! When I went to check the main battery terminal leads if found the nut, that holds the two brown wires to the negative terminal, was loose. Quick nip up with a spanner and jobs a good 'un. This also sorted the central locking problem we've had since we bought the car, double result!
