Hi my battery light has come on it's only dull but on constantly whilst driving, iv checked and batt is ok and alternator is charging at correct voltage.any ideas welcome.
Cheers for any help Ben

 

Thats mad, was gonna put same thread up lol. Mine did it tonight but flickers on and off now n again. Not checked anything yet. But when mine revved low it lit up more. I reckon alt is on its way out?

 

mine is doing the same checked battery and it 100% charged and a couple of weeks old so thats fine alt is charging like it should be, any idea's wud be great. Cheers dave

 

Mine has always done this. Its only very dull. Can only be seen at night time with the lights off. Glows a little bit when using the windows (obviously). But as the battery has the correct charge and the alt works fine I don't worry about it.

 

Wedge mine is doin exact same thing, sometimes flickers hope it's not a wire earthing out.

 

Anyone got any pointer as where to start lookin?
Cheers Ben

 

Check out the blue wire (otherwise known as the excite wire) that connects to the starter motor - these break down over time and can cause the majority of starting/charging problems of the S2 and also cause the battery light to glow - make sure when you check that you check the wire inside the blue sheath is actually intact as the wire can break down over time within the sheath and although it looks good can still be damage inside.

 

Also youll find a connector on the blue wire near the alternator this tends to corrode inside over time so unplug it and clean the connection this cured mine

 

Spot on

 

Cheers lads ill have a look tonight,gonna get a new alternator to eliminate that.

Yeah worth getting a new altenator aswell as where they are on the car they get all dirt and water in them and start to play up. With a new one and cleaned connections it should cure the problem.
Also check what charge your getting on the battery when its running!

 

Check your earths and the wires for alternator and battery in good condition

 

Mine did this awhile ago now and ended up being a poor connection in the ignition block under the steering column the red wire i believe. Also i swear there was a thread on here somewhere with someone had the same fault and tells you how to cure it assuming ur altenator and battery are ok.

 

Can a new excite wire be ran seperate to the loom?

 

blue wire was halved chaffed and touching bare metal on car when mine had light on mate

 

Hi the next problem I have is my current alternator(been told sierra 1.6/ 1.8) has a multi v groove pulley on and the standard is a sigle v, is it possible to just swap pulleys?this is turning in to a nightmare,I can get easy access to a new standard rst alternator but really struggling to find a sierra one,sorry for the essay.
Cheers Ben

 

Halfords should do them i got my xr3i one from there.

 

Seriously dont go to Halfords for anything - clueless chavvy mugwits - end of !!

This is why they have places called motor factors - doh !
