mintalkin Posted April 25, 2009 Share Posted April 25, 2009 first thing to check would be that you have 14.5 volts at the battery terminals with the engine running, also the alternator connecting clip can throw up problems. Quote Link to comment Share on other sites More sharing options...

FocusKid Posted April 27, 2009 Share Posted April 27, 2009 That grey clip is what i think your talking about. it is a voltage regulator built into the system for the alternator. The ford focus is notorious for this problem as i have been through 3 seperate alternators all with this issue. Look in the area containing your Relays(dont know if thats what you call them) Under the dash....it should be like R24 clicking at you. This means there is a load not cooperating in the system. And most likely will lead to your alternators demise. i had it happen on the highway car started to lose power dash cut out then the car just stalled. Couldnt even roll start her. Look at that relay and ask ford to check your voltage regulator Quote Link to comment Share on other sites More sharing options...

With respect Adam, by the very fact of you posting this on a 15 year old thread, I'd be taking it to a competent independent garage. You could try and use a diagnostic tool called ForScan to get you definitive fault codes which will give you a better idea of what is wrong. I would start a new thread stating specifically the actual faults you are experiencing... 3 Quote Link to comment Share on other sites More sharing options...
troy45 Posted February 6 Share Posted February 6 Looks to me like it could be the alternator failing then power-steering throwing its hand in as the battery voltage starts dropping Quote Link to comment Share on other sites More sharing options...

troy45 Posted February 7 Share Posted February 7 I was going off the user with similar issue listing a 2006 Focus in their profile, not actually referring to the ST170 from the historical original post Quote Link to comment Share on other sites More sharing options...
