Morning,

 

Curious to see how many other alternators have been replaced on Mk2 Superbs without stop start?

 

Any instances where the Alternator warning light was cured by something other than replacing the alternator? My car is at an independent and hopefully getting fixed today. They're getting a second opinion from an auto electrician before stripping things down to be sure it is the alternator. Mentioned it could be dodgy connections which would be nice, but expecting the unit to be re-wired or replaced.

 

The light came on about 15-20 minutes from home and was intermittent. All non essential electrics off including dropping to position lights in well lit areas and it made it home, and subsequently restarted and made it to the garage. On the occasion things were a bit too quiet to be comfortable on position lights only switched the mains back on which made the warning light far less intermittent!

 

Yeah, if I'd realised this year would entail front lower control arms (bushes shot), front wheel bearings, and an Alternator I would have changed car! Now hoping for little more time away from the garage next year!

The temperature was remained at the dead-band 90C position, no cooling system fault light, and as far as I'm aware no squeaking from any belts!

 

Interested to hear how far people have made it with the light flashing at them too. I guess the only major loads are the injectors and fuel pump. The display (Columbus was off) and ECU should be very efficient and the ECU will be capable of running down to the single figure voltages it'll experience on cranking.

Check your alternator regulator slip ring  carbon brushes for wear.

Carbon brushes from me as well.
