Ford Alternators - corax

I have lost track of the number of Fords that seem to need a replacement alternator. A colleague at work needed a replacement on his Fiesta TDCi.

Another colleague had friends who had to replace their alternator on a Focus.

I just read a thread on here where someone needed a replacement on their C max.

Some friends have also needed to replace theirs on a C max.

Car Mechanics had a Mondeo as a project car and that needed an alternator.

What is it with Ford alternators?

Who makes them and why do they fail so often?

Quite often they are changed unnecessarily because the 'technicians' don't diagnose the charging problem correctly. The most common charging fault with Ford's is the piece of wiring loom going to the alternator has the wires break in it about 12" from the alternator.

And it is not only Ford's, I got called to a local garage to diagnose a fault with a jag that they had changed the alternator on and it still was not charging, That was a wiring fault but, The customer was still charged for the new alternator that he didn't need.

I have never had a Ford alternator(or dynamo) fail and that's 55 years of cars-not all Ford but quite a few.

My Ford Capri did 255,000 miles before I scrapped it. The (original) alternator still worked perfectly!

My Ford Mondeo did 203,000 miles before it died. No alternator problems whatsoever.

Alternator faults where common on our old fleet of ford transit's.

im now wondering if the wiring was the solution!

My friend has owned several Transits over the years. He told me one that he was always repairing or replacing the alternators on them. Sometimes he'd even bought brand new (not reconditioned) alternators but they didn't last any longer than the others.

The chap who was responsible for running a fleet of Transits in the hospital where my friend used to work also always kept spare alternators in stock. He also said they were always failing on Transits.

My friend puts the continuous failure of alternators in transits down to the high revving of the engines. Their gear ratio's are so high you could almost climb up a block of flats in one! The downside, however, is that you need to rev the guts out of them to get up to any sensible speed, and he believes it's this that kills the alternators.

I think you mean their gear ratios are so LOW? Nevertheless, this would not make the slightest difference to the alternator drive, as it will be geared to work at optimum RPM via pulley diameter on any given engine/vehicle. Like other posters have said, more likely a common wiring problem as the "technicians", are only trained to swap-out parts until they eventually (or maybe more likey never) find the ACTUAL root cause. Meanwhile the punter gets fleeced.

But what do you expect when these guys paid rubbish money even though the garage charges you £90/hour?

spotted someone push starting a 08 plate transit.

I thought it was a big no no? wrecks the timing belt?

How can push starting be different to using the starter-both just cause the flywheel to rotate!

Surely Transits can be high geared or low geared-you can specify the final drive ratio when you buy!

You are perfectly correct on all counts plus Fords are no more a problem than any other manufacturer with alternator failure.

Having designed (heavy) vehicle charging systems, I cannot agree.

Ford are an organisation in which cost control is paramount. The purchase of specialised components from external suppliers is anathema to them insofar as they are then funding the profits of another company. They therefore tend to make some high volume specialised components themselves.

Lacking the knowhow of specialised suppliers such as Bosch and Valeo, Ford have produced some truly dire components. For example, back in the days of carburettors, we were blessed with such delights as the FoMoCo or Autolite "instrument" - and the business approach continues.

Electrical components are no better (steel busbars in lighting units which rust, for example) and I judge the long term prospects for these and others from this source to be limited.

Pay your money and take your choice. I respect Ford hugely as a tightly run business with razor-sharp cost control and marketing acumen. I also choose not to own any of their products.

My BIL used to work for Ford as a senior design engineer in both car and tractor divisions. He would concur with 659's analysis. (he drives a W124 Mercedes estate and a late 2009 C Class CDI Mercedes estate and collects old English motorbikes which he removes in his W124 ... and restores at home)

Over the years I have owned many Fords and they have been fitted with either Bosch, Motorola, Valeo, Lucas or in the case of the last C-Max a Denso alternator.

Never owned a Ford with a "Ford" alternator.

Only one that has ever failed was a Lucas in a Mk 3 Escort just out of warranty, Ford still replaced it.

Motorola were at one time owned by Ford-as were Philco.

We are not talking years ago when carbs were the order of the day.

I wonder who makes electrical parts for fords now with their cars and vans quite capable of doing 200k without much bother as I said they are no worse or better than any other make there are some mega design mistakes made by other makers that will cost a lot of money to put right so lets have a little pespective.

From the perspective of an owner of old Beema's run on a shoestring some years ago.

Bosch alternators...have had minor issues with two of these. Nowt wrong with the actual alternator just bought a new gubbins that bolted into them. New carbon bushes and I believe a rectifier pack. Very satisfying to spend I think it was eight quid and avoid replacing an expensive alternator. Once fixed they ran for years with no trouble.

I expect with the modern Ford product this option is not available as either it's not a seperate part or you can't buy the individual part as nobody makes it. Progress huh?
