*Battery/Alternator Warning Light Help*

[RikH]

My Battery light on dash has illuminated twice in total.

First time was 2 weeks ago when i was really giving it some, it came on as i braked hard for a T junction. It came on and went off for no more than 2 seconds, it then stayed off.

Today driving home from work on dual carriageway pulled out to overtake and it did the same, popped up for 2 seconds max then went off.

Car doesnt feel any different, and i didnt investigate further after 1st incidence as it didnt do it again.

Just checked manual and it says its the Alternator warning lamp.
"if comes on although the v-belt or ribbed belt is not broken or loose, one can drive on to the nearest technical service centre"
"if warning lamp lights and the belt is loose or broken DO NOT DRIVE ON-the coolant pump is no longer being driven. The belt must be checked or renewed"

Had a quick gander at all belts and nothing is slack or loose or worn. Could anyone direct me to the particular one??
Anyone had any experience of this?
Would this be a sign to replace the cambelt/waterpump/impeller etc?

Cheers

dodgy connections to the alternator? or alternator on way out?

Ive got a tester which you plug in your cigrette lighter, tells your battery voltage and altenator voltage. Which may come use full to see if you alternator is playing up or not! Cost me around a £10 around a year ago

Now dont shoot me down here

but are you sure it was the battery/alt light and not the oil light ??

Reason is that under heavy braking the oil will move about in the sump, if the level is a bit low you could get this. Would not think accererating would do this though......

update

had it on VAGCOM-no codes at all for this????
tested battery and Voltage is perfect when off and at idle, drawing the correct amounts
took off terminals and check and all are clean as a whistle?
belt is tight and good cond

anyone any idea's now?

just going to have to keep an eye on it i guess.......

 

[DodgyDave]

No probs ... as both are red and ony come on when you are pushing it's not always easy to see what one it is

I'd go for a loose earth from alt-engine myself, it sits quite low and can get soaked and start to rust, then any movement sets it off......
