    have you checked the voltage across the battery when the car is running, your alternator could be on the way out
    a good idea would be to change the tensioner of the belt if it is squeaking

    Check the aux belt-if its cracked you will need to replace it-Their is a belt tensioner already there-Check the battery is connected properly-loose connections are not good also as said check the power when running.If the Alt is on its way out yu can get a 140 amp Alt for £30 I'll dig out the link and then its very easy to change it

    Link for alt's http://pakrhythm.com/

    To change an Alternator

    1. release belt tensionor
    2. move belt off alternator(no need to take the belt completely out unless changing the belt)
    3. undo the 2 bolts holding alternator in(1 at top,1 at bottom)
    4. wiggle Alt loose
    5. Undo electrical connections

    Putting in the new alt is the reverse of the above It will require wiggling to get it back in as its a very tight fit but whole job can be done in 20 minutes

    I would change the belt Its self tightening with the belt tensionor so you can't really tighten it yourself The belt is not very expensive and fairly easy to change
