Hi all

 

Battery light followed by the power steering and ABS lights come on this morning on my 2006 TDCI Fiesta while driving to work

 

This afternoon it just managed to start. Most off the panel lights came on and the speedo meter also stop working as well as the trip computer.

 

I check the voltage while the car was idling and only got 5 or 6V ????

 

Jump starting and idling got it up to only 10.5V ???

 

Are these alternators a sealed unit or can the diode pack/ voltage regulator be changed.  What else can be faulty ??

 

Any advice will be appreciated.

 

Thanks in advance

 

Nico

Is there a belt driving the alternator?

Hi Ian

 

Yes it is driving by a belt which also drives the a/c

Nutlang, a lot of auxiliary pumps are run off the same belt as the alternator. First thing that springs to mind is the belt. Is it tensioned properly?

Check the battery for a dead cell, can you charge the battery for at least 12 hours off the car and check the voltage, should be just over 12 volts for a good battery or get it to a garage for a short circuit test.
