24v keeps stalling

Hi Everybody,
I wonder if you can give me some advice. I have a low mileage (66,000 miles) Cosworth Ultima 98R reg Scorpio which is becoming unreliable. At the moment it keeps stalling when it is on tick-over or when running slowly with my foot off. It starts straight away but the instrument cluster resets and the trip computer reverts to metric. I have done a check on the instrument cluster and it says the voltage from the battery is 11.1 volts, which seems a little low to me, rising to 13.7v when the engine starts. The instrument cluster regularly resets on turning on the ignition but does not revert to metric. I did have an ignition relay burn out a month or so ago but I don’t know if this is significant. I have tried talking to my local Ford dealer but can't get anywhere. Can anyone suggest where I go from here?
Brian

The instrument cluster keeps resetting, huh? Sounds like a dying battery...
Change the battery and if it doesn't help check the alternator, but there should be no need for that as the new battery should solve the problem.

Hi Brian,
does it stall every time you are at idle or just the odd time?
does it have a rough idle?
could be idle control valve/ fuel pressure regulator
possibly sticking aircon compressor, does it stall with the aircon off?
have you cleaned the MAF?
would be worth an OBD scan if you can get one

about that stalling Stuart, I was thinking dying battery + worn alternator=stalling
idle control valve/ fuel pressure regulator sounds probable but has nothing to do with the instrument cluster resetting... i bet it's something simple and battery related

If the battery and alternator were both in such a bad state that they caused the engine to die then surely it wouldnt restart..

it could restart... did a test once you can start it up to 7 times in a row and then just switch it off on a dying battery before it's totally flat before you say anything, the test wasn't done on my car [i'd never be that cruel to it ]
anyway if he can get the car running for a while before it stalls it will recharge a bit eventually... JC may also have a point here with that neg. lead

lol
I'm in agreement about the dying battery but i think the stalling problem is a different issue

hi there
i'd good for the battery theory.
i would think with the low voltage, the car is shutting down various electronics.
do you know when the battery was changed? maybe take it to kwik fit or the like to do a dis-charge test on it.

Thanks for the replys.
I have checked all the batery conections again and they are fine. I did check all of this last month when I was trying to solve the Ignition relay problem.
Yesterday it stalled in heavy trafic about 5 times in a row before I turned back for home and then stalled every time it returned to idle for any length of time, including rolling down a hill behind a slow moving car. It always started cleanly. When it is just ticking over, all is smooth and fine until it just dies. I started it again last night to check a few things and it was fine, except for the dash reset almost every time I turned on the ignition. The fuel computer resets every time the dials do but only resets to metric when it stalls.
It all seems very confusing to me. I can understand the dying battery idea on the dash but why does it stall?
Thanks again for the ideas. I will try my other battery from my other scorpio later and let you know what happens

hi there
it stalls because of the low voltage.
we've seen it lots of times but with starting issues. members come on and say the car turns over ok, but won't start. we tell them it's the battery and to try a jump start just to get going. next thing it starts!
the scorpio seems to be very sensitive to voltage.

Brian.
The little lead to which JC refers has been known to fracture inside the insulation causing intermittent symptoms as described.

I say idle control valve need clean if stall when you stop car like to traffic light...
My 24V altenator volts is 14.0-14.2 but my battery is very new like 4 month old.
But look motor cabel too... i can say at its not new if cabel is broke...

Having had similar "stopping" issues could it be fuel pump, mine was/is.

I'm not convinced, if the voltage was so low as to cut out the engine it wouldnt restart, the battery would be dead.
The alternator on its own should be providing more than enough juice to keep the car running and if the alternator AND battery were BOTH broken it wouldnt be starting..
Am i picking you up correctly Brian in that its starting fine, the problem is that it stalls at idle?

hi Stuart
you could well be right and it's 2 issues.
it certainly won't do any harm to clean out the idle by pass valve anyway.
my thinking is that the voltage is dropping at idle and the car is then shutting down. i wonder if a DTC would register?
Brian, can you do a climate control reset and see if you get an error code on there.

Yes Scorpio_man would love to do a climate control reset but not sure how - could you tell me?
Thanks Highlander and have to say I agree with you - I can start the car but that's when the dash resets itself back to metric each time. The car stalls when idling or whilst driving - it happened when drifting down hill or behind slow traffic so was not accelerating at the time.
Thanks for all the replies so far - much appreciate the help.
