CHARGE ALTERNATOR WIRING - BLACKTOP ZETEC 2.0
BlueIan - 2/10/18 at 01:54 PM

HI ALL,

I HAVE A STANDARD 2.0 BLACKTOP FROM A FORD FOCUS WITH A STANDARD 80A ALTERNATOR FITTED.

DOES ANYONE HAVE A WIRING DIAGRAM FOR THE 3 PIN PLUG ? TO WIRE IT TO A BOG STANDARD SETUP ?

HAVE TRAWLED THE ELECTRICAL SECTION TO NO AVAIL, THANKS IN ADVANCE

The short answer is you can not.

The ford alternator of that age has what ford called “smart charge” this is where the ecu controls the alternator cutting charge at crytical times to reduce load and there for emissions. It is not a simple switched signal.

The alternator will self excite if you remove the three pin plug but it has no way of putting the light out on the dash. This is again information sent to the dash from the ecu.

The silvertop alternator I am told will bolt in place and is a traditional unit.

If on the other hand you are using the focus ecu have a look as the PIN numbers are on here.

Many thanks Big Wasa / Big Vee Twin,

looks like a change of alternator as I am using a Nodiz with no ford ecu.

thanks again Ian

Looks like I've just fitted a type 6 to the ST170 engine in the Quantum. It came with the main cable connected to W, so that's how I connected it into the car. I haven't started it yet but it hasn't got an ign light on dash. Maybe I just need to move that across to B+ and see if that sorts it.

It won't work on W, that's normally used for original equipment rev counters.

Hi Warren - in that case the ST 170 alternator - not connected except for the power lead - will self excite and self regulate? Or will it self exite and overcharge?
I'm thinking it may be simpler to just pull the plug as it were.
Sorry if this is a dumb question
