Hi, I've had the battery/alternator light comming on for some time now all you had to do after start was raise the revs slightly and it would go out. Engine turns over no problem and starts. The last couple of days I have had to keep the revs up for quite a while or drive away and then the warning would go. I've checked the battery (mercedes) don't know how old not 9years surely and the voltage is as follows:-
Before start 12.15v
After start 11.75v
After revs 13.80v

Does this indicate battery or regulator or alternator?
Anybody got any ideas before I start spending money on new parts?
Thanks for the help..

Michael.

The would suggest that the carbon brushes are loosing contact on the slip rings in the alternator, it is not a faulty reg pack.
I would drop into a Bosch service center, and they will know what to do, they charge the same as an indie,½ the MB price

Theres the problem, one bosch service center in ireland as far as I know, way down south, to far to go really. Are they servicable the alternators?
They look awkward to get at tucked under all the turbo gear!
Thanks for the advice..

A complete regulator and brushes costs about £15 from bosch, its held into the back of the alternator by two 4mm bolts which may be accessible in situ without removing the alternator.

Thanks Wireman, It would be good news if it is possible to change in situ. What is involved in swapping the brushes? Malcolm do you have any info on that and changing the reg pack?
Thanks guys this is a great forum!
