Hi

I need some of advice because i have quite a big problem with my w124 3.0 with KE-Jetronic and i don't have any idea how to resolve it .

Battery after one night is completly dead. I measured power consumption by connecting in series multimeter. Consumption was about 0.01 amps so i was quite suprised because thats good result. After a while I found something strange. When I started the engine, then I stoped it and turn off ignition I still have power on whole kejetronic... Idle speed valve, air flow potentiometer and also diagnostic socket (between pins 3 and 5 there is 12,5V). So I looked at OVP relay, and Voila. When i took off fuses from that relay, coils and ABS pump made "click" and power was gone I looked into diagram on OVP relay. Pin number 30 this is constant plus, 31 a ground and at the pin 15 power is only when the key is on. So I thought that something is wrong with ignition and pin 15 still have power even when key is on. But unfortunately no Even if I pull of the key and close the car, pin 15 does not have power. I don't understand how it is possible that coils are still egaged even if pin 15 does not have +12V. I changed OVP for new one but still the same.

Could you give me some advise? :-)

Thanks a lot.
