You could do it and you could pick an alternator off a scrappy or used car breakers for a lot less. Someone recently bought one for about £20, fitted it and it solved the problem. so I dont see it being too bad!
I tried to find some decent manuals online on how to change alternators but I couldn't find any.
Could you please point me into the right direction?
All I have done so far on my car is changed fuel injectors and spark plugs Nothing else really... =]
Certainly the alternator sounds to be struggling to cope with the load being put on it, so it may be worth sourcing one from a scrapyard and trying that.
The ECV can be removed and cleaned, which wont cost you anything and is a good place to start!
But then why when I tested the alternator it was showing 14.9V (with my heating and headlights turned on) instead of normal 14V-14.5V?
It's even more than is required..So how can it still be alternator?
