Hello,
as it says, my battery light is glowing dim when at idle
and low revs. Blip the throttle and out it goes.
Read the wiki - is this likely to be the brushes on the back?
2.ol a/c 1980
thanks in advance

it will be either muck or brush pack, whip the brushpack out and give it a clean with brake or carb cleaner, and check the brushes.......
could also be the belt slipping, but i doubt it

mocki,
thanks for the quick reply!
Whip the brush pack out....will this be blindingly obvious when I look at my alternator?? What tools do I need to remove it? The brushes have to be more than 7mm, right?
Do I need to disconnect battery etc etc?
Can I buy replacement brush pack, or is it new alternator time?
new belt, and no whiny slippy noises, so don't suspect that.
Learning sommat new every day....

Yes, you can buy a new brush/regulator pack.
I've never disconected the battery but that doesent mean you should.
Two screws hold the brush pack on.
Brush length = 13mm new 5mm buggered.

I would definitly disconnect the battery.
The big terminal on the back of the alternator carries the full power of the battery, and a short from there to earth, via a spanner etc, is not to be taken lightly !!
