Over Voltage Relay

Hi All

I have a 190e 2.5 16V and one of the fuses in the OVP has blown I replaced it but is blew as I started the engine again. I have worked out that the fault lies on pin 87L. Can any one tell me where or what this pin supplies.

Thanks in advance[/b]

hi

Thank you for the quick reply. My heart sank when you said pin 1 of the ECU does that mean that the ecu is faulty or has a short on pin 1?? Also do you have a wiring diagram as this would be really helpful.

Regards

Check main fuse box p2 [redwire] this goes to ecu pin 1 [redwire] Remove wire both sides and check continuity between them.
