Mercedes C220 Petrol 1995 - Will not turn off, runs with ket out Archived Message

Hi Guy's
I have this Merc which will not turn off. with the ignition key off it will carry on running, or if stalled the dash warning lights are on until the OVP relay is pulled, relay back in and everything is ok until key on and off again.
With the fault pins 3&4 are fluctuating 8.5v to 10.5v pin 2 is 9.8v, all the other pins are nbv apart from pin1 which I assume is earth at 0v.
Does anyone know where pins 2, 3, 4 go? Haynes wiring diagram denies any existence of an OVP relay.
Regards Steve Harvey
ps It's not bulbs!
