General Chat Thread, Alternator in Ford Fiesta..are we being ripped off? in General; 12.7 is a healthy battery voltage, but it may still be faulty.
As it's a Deisel it has no ignition ...

12.7 is a healthy battery voltage, but it may still be faulty.
As it's a Deisel it has no ignition system to run, and it will be mechanical injection. So as long as your not using anciliary devices such as lights, demiste, fan, radio. the main drain will be starting the car.
This should be ok for a few attempts if the car is an easy starter and may continue to start long term with a faulty alternator giving some charge.

When the alternator is charging the battery the voltage across the terminals should be 13.7v, or thereabouts (or was it 13.4v). In any case >13v. If you see the voltage above 13v when the engine's running, the alternator is likely to be OK, or at least serviceable.
Batteries can suddenly give up the ghost in cold weather. They can be fine in mild weather, but when the temp drops below a magic number they die.

the voltage should be about 3-13.5 when charging, when I was a mechanic we used to use scrap alternators all the time 9/10 where fine as where other second hand bits.
Personally if it was my fezzy on a 98 I'd be thinking about changing the motor especially if I'd had it a while, could be a sign of other things about to go wrong.

They said they measured it and there was no charge with the engine on. Unfortunately I have to take their word for it - couldn't go in to check as I'm at work 12 miles away.

Well, perhaps you might be prejudging them. If you've committed the work, get the job done. Afterwards, phone a few other places for quotes to see if the price is a bit steep. It's never nice to pay too much (if indeed you have), but hindsight won't help. It's not the end of the world, perhaps the job on your car is an awkward one.

You are in london which means the hourly is going to be quite high.

Just weighing up if I do my coolant control valve myself or leave that one to the garage as it's a pain doing it on the drive.
