Just been to another garage, he said as there is no history about cam belt, and with car having over 126 thousand miles on it, it's likely cam belt may of slipped, and timing may be slightly out.

He said that would cause it to not run right if it has slipped.

What do you guys think to that.

I would say touting for business although belt would need doing at that mileage i dont think this is your problem like others have said pointing in the direction of bad earth loose conection to me there are no leads chaffing on body work anywhere just a thought but i would think that would blow a fuse myself i would double check all the earths again

I have found that, if I totally disconnect alt, (3 pin plug, and thick red power lead) and then start engine, I can switch on lights heater etc etc, and lights do not go dim revs do not drop.

But reconnect alt and all problems start, alt is kicking out 14.7v

I called RAC out again, after I fitted new alt, he checked voltage at battery not started, and with engine running, he says its perfect.

He can not understand why as soon as any load is switched on, engine goes weird, and lights dim, as the charging system and battery are perfect.

I have come to the end of what i can do now, am going to Fords tomorrow, and get them to fix it. No doubt it will cost me a fortune.

Can I just throw this your way guys.

A friend just took look at my car, he says idle control valve (his reason is)

With engine running, he disconnected idle control valve, revs drop to to nice and quite, no shaking.

Turned on all electrical items, and revs did not alter, no engine shaking absolutely perfect, no diming lights.

What do you reckon.

Fords have just looked at car, they say no faults found.

Am stumped now.

What is correct idle speed? Mine idles at 1 line below 1, and when i switch on heater or headlights or press on brake pedal, just enough for brake lights to come on, it goes down to 2 lines below 1, could i just turn screaw to increase idle.

I will give £200 Cash to any one that can come and sort this for me please

The car should idle at 750 rpm. If it was running fine with the ICV unplugged, why not just run it like that for a while and see how you go. Given the year of your car, I would still say an earthing/short circuit problem. Maybe a possibility of the ECU not receiving information, due to some sort of corruption/water ingress,etc.

They said there was no update.

I honestly can not see it being an earth issue, the reason I say this, is:

If I totally disconnect alternator, remove 3 pin plug and power lead, and start car and switch on all lights heater etc etc, engine revs do not alter, lights do not dim etc etc.

So I don't think its a earth problem, alt is a 80amp one, I was going to go for a 110amp, but did not know if this would cause problems, as factory one is 80amp, I stuck with 80.

This is really bugging me now, I bet it turns out to be something small thats causing this.

If I where to get a ecu from a donor car, what bits do i need to get with it to make car run.

I know am clutching at straws but I desperatley want to correct this problem, so will try anything.

Disconnecting the 3 pin makes the alternator act as a conventional one without input from the ecu about demand or load.

So of its playing up with it connected then It would seem the ecu is not doing as it should

We all know it takes a live and neg for a bulb to work, so drivers side headlight, i cut the earth wire, but yet headlight still works, not bright, but it does work.

Where is the main earth wire for front lights, am thinking disconnect original earths, and put new earth in for front and back lights.
