Just had a rude reminder of why I prefer old cars to new ones:
Finished work at midnight on Monday and found my Saab wouldn't unlock on the plipper for my journey home. Opened it with the manual key and found no electrics, everything dead.
Managed to jump-start it but engine died within seconds of disconnecting the jump leads. Blagged a lift home as I didn't want to be hanging around waiting for a recovery truck.
Got a lift to work yesterday afternoon, put a new battery in it and it started on the key, Hooray!!
At two in the morning and half way home a warning message comes up on the head-up-display saying "BATTERY NOT CHARGING, MAKE A SAFE STOP AND CONTACT SERVICE CENTER."
After a frantic Apollo Thirteen style shutting down of unnecessary electrical ancillaries to save battery power, I got it home with whitened knuckles from the dread that it would die on the move in the middle of nowhere. In a gale. With no mobile phone signal...
A bit of internet research this morning suggests that the alternator has failed, a common problem on the 9-3, apparently.
Now, amongst other things, I'm a qualified aeronautical engineer.

I know how to fix stuff, and, if it was my trusty Triumph generator, I'd stand in the engine bay, undo a couple of imperial bolts, put new brushes in and Robert would be my mother's brother.
So, can you buy new brushes for my 'Saab' alternator? (read Vauxhall alternator as the 9-3 is really just a Vectra with the word 'Vauxhall' crossed out and the word 'Saab' written on it in crayon).
No.
The only option is a new alternator. And the cheapest I could find is a hundred and seventy quid, which I suppose isn't
too bad.
As I don't have a Haynes manual for my Saab I thought I'd better have a look on the owners' forums to see if there were any useful hints and tips about replacing the faulty alternator.
Why yes!
It seems you need a star-drive socket to undo the special bolts holding the alternator on. And it seems that Saab used three different sized bolts depending on what type of snow was falling in TrollhÃttan on the day your car was produced. And it seems that you can't get at the alternator to check which socket you need without removing the o/s front wheel. And the o/s front inner wheel arch. And the sump cover. And, because you can't actually remove the alternator through the fag-paper sized gap amongst the air conditioning pipes without damaging the a/c system, it's best to remove the o/s drive-shaft too. For which you need a specialist tool.
AAAAAAAAAAAAAAAAAAAAAARGH!
So, I can build myself a superb recreation of a fifties sports racing car using hammers and spanners and manual skill. But I can't change two quids worth of carbon brushes on my modern car without handing my credit card over to my local Vauxhall dealer and keying in my pin to the tune of three hundred and sixty quid. Money I'd rather have spent on my Spyder.
I'm seriously considering making the inside of my Sammio water resistant, buying some motorcycle leathers and using it as my only car. At least then, when it breaks I know I can fix it.
