1989 Mercedes 190E OVP Relay

Hello I having a hard time with a ovp relay at first the car stall lost all power to the fuel pump and no spark. I check anything I could check and it seem there no power to pin 15 of the ovp I try a jumper wire from a key on hot wire to pin 15, it work at first the car start and ran good but later this wire shorted out on me it seem the ovp shorted and pin 15 is hot out not in ok I have a ovp coming but what I need to know is why I not getting power to pin 15 ? I have a poor print out of a Alldata drawing it show as far as I can tell the wire to pin 15 come from the Ign Sw to a Electrical center then to the ovp. What is this Electrical center ? how can I test to see if my bug is there or in the Ign Sw ?
