I removed the inlet manifold on my 02 bug after having a fuel smell, ReFitted its all good now after it was running for ten mins the alarm went off ( poss low battery?) i came to it today started it again it ran siren went off again and battery went flat.
It looks like the alternator isnt charging, i cant check voltages till tomorrow when i recharge battery at work.
The earths and positive and the green connecter were all fitted.
Coincidence the alternator has failed or have i missed something?
thanks

 

How long was the battery off?
What condition is the battery in?

That model has, IIRC, a so-called smart alternator, which doesn't charge unless it detects a load across it, so folk run with internal fans on, lights on, hrw on etc.

 

the battery was off for a week
Ill test and charge that tomorrow at work. But im pretty sure battery is ok
fans were on as were the lights and hrw then it ran flat.

​​​​​​

 

a week max
battery is ok ill charge and trst it tomorrow at work to eliminate it.

 

Once it's charged and you are certain it's OK and not dropped a cell, try running the car with lights on.

 

thanks alcazar
Battery is knackered it charged but the tester we use failed it so must be a dead cell like you said
ill fit a new one at the weekend
