Flashing Lights After Dead Battery

[wilde]

Hi,

I 've got a 96 xantia turbo diesel. Left the lights on and the battery went dead. I jumped it and the car started but when I start and finish the dips flash on and off for a minute or so. Also three days later (after a two hour drive the day before so I guess the battery would have been charged (no red no-charging light) my wife go in after work to find the battery too long for the car to start - AA came and charged it. Should I get a new battery? What's with the flashing lights?

Many thanks in advance

The headlights flashing on + off is the alarm system operating, it sounds as if the siren has been turned off or isn't working.

 

If the battery keeps going flat then either it's knackered or it's not being charged. If you have a voltmeter and connect it to the battery, if the alternator is working correctly you should see a voltage above 14v with the engine running
