Hi, I recently bought my mondeo and when i first started it it was struggling to start and was very noisey from where the altenator is .. I havent took it back to the garage yet but i have notified him of it. Then this morning my car started as usual and i drove it for around 20mins then i nipped out in it and it wouldnt start like my battery was dead, so i get a jump start and whilst it was running i tested the battery to see if my altenator was doing its job amd with everything off but the engine it was around 12v then once i put my side lights on and heaters and it dropped to 10v. Does this mean my altenator is going or could this mean i just need a new battery. its worth mentioning that the battery is the original battery from 2006 and is a calcium battery.

Any advice would be much appreciated because if it is the altenator it should be covered by my warrenty

Thanks

 

your alternator is not charging mate could be a wiring fault also?

plus i not sure if these have smart charge on them

 

Thanks for fast reply .. Ill take it in the garage tomorrow .. I dont like losing my car if i can help it as cycling in this snow is not good .. Oh well least its covered and its not costing me .. Thanks again.

 

smart charge it is .alternator bollixed or 3 pin plug / wiring fault .pull the 3 pin plug if it makes no difference definately the alternator [it goes to default mode 14 volts 50 amps]

 

yeah smartcharging system on them you need to disconnect the small multiplug off the altenator then check charging right at the altenator if its around 14v then its wiring or smartcharging fault which is ecu controlled

 

Thanks for the replys. gutted im without my car. could it be related to the noise thats coming from down where the altenator is or is it normally a noisey car

 

100% a brake in the wire or alternator it's very unlike it to the smart and yes it has got 1

 

they are noisy engines mate
