Stilo DANGEROUS FAULT?

My Stilo 1.9 Diesel TD Sport - Strange fault!!

I was away from the car for some hours - parked on my drive way - key out of ignition and locked.
When i returned - the car all by itself had moved into the side of my house.
Apparently the Starter motor had engaged and moved the car forward slowly.
It was in gear with the hand break on.
It completely discharged the battery in doing so.
Recharged the battery and connected and the starter motor runs straight away with no key in ignition?
Also the instrument lights flash on and off.

As your starter is permanently engaged then disconnect the starter relay wire, the smaller one of the two- brown and white wire- (not the big one with two red cables)

If the starter is still engaged with that wire disconnected then the starter relay is jammed or there is an electrical bridge across the two connections on the starter relay


If the starter is no longer engaged then the problem is within the ignition switch. This is very likely as you're also getting dashboard lights going on and off


There should only be 12v at pin 3 on connector A at the ignition switch or on the brown /white wire at the starter relay when the ign key is at the start position

1.9 jtd electrics got mind of their own

Hi
My Stilo 1.9 JTD has developed a mind of its own.
First thing that happened is the Starter Motor started running other evening when car was locked and parked overnight.
I recharged the battery and refitted.
The starter still turns by its self without key in - I have checked the starter relay/ solenoid that is OK.
It is getting a permanent feed to the starter relay??

With key in ignition - multiple errors come on display dash board then after 10 secs instrument dash board lights flash on and off continuous -after a minute or so it dies.
I suspect that a technician could not even plug in a tester to the Computer box because that requires power to it - I have no idea where the main computer is , so I cannot check to see if it has power.

Now - one of the relays (board on top of the battery box) - clicks away all time - even with key out of ignition.
I have checked the T4 connector - that is good - I checked all other connectors for corrosion etc - they seem OK.

Any one know where i can get a Schematic diagram for this car - I have looked at the Haynes Manual - they don't seem to have one for a Stilo 1.9 JTD?
I am really stuck on this one!
Any ideas please?
Phil
PS - I am new to these forum things - so please forgive any mistakes I make!

Hi welcome to the forum, this problem arose quite recently on here https://www.fiatforum.com/stilo/220623-stilo-starter-turns-non-stop-no-key-ignition.html

Just merged - so we can keep an eye this problem

My missus's car has exactly the same fault she tried to drive the 500 yards home and the car stopped completely. But now everything seems fine except it wont turn over, I'm guessing she burnt out the starter? If she did then what caused it to continue to turn over? Anyone got a solution?
