There were many types of this part(6,7 and 9 contact part) but for all of them are 3 contacts in common - 30(the positive coming from the battery), 31(the ground) and 15(the ignition ON). With a help of the multimeter which has the diode check function you can check your OVP if it's within the specifications(0.4-1.5V). If the OVP fails this test then check the fuses(the buzzer on your multimeter) and if you get no conductivity then your OVP is bad and has to be either replaced or soldered). Let's keep our legends on the road, Happy Mercedesing! <br /><br />What am I talking about?<br />My topic is the KE-Jetronic injection system which I try to demystify as much as I can.<br />For all of you to understand the system in brief - Developed in 1973 and being mounted into cars up to 1993 as it went in history. But why these to letters!?(KE) K(from German "kontinuierlich" meaning continuous, without interruption) the MECHANICAL injection system on which the fuel starts flowing from the fuel tank sucked by the FUEL PUMP and delivered to the FUEL DISTRIBUTOR which sends fuel to the INJECTORS while the majority of it flows through the FUEL PRESSURE REGULATOR through its return line back to the fuel tank again. The letter E(electronic) has to mark the electronic sensors (the developement starting from early eighties) which had to inform the ECU about the current state of the engine so that the ECU(Electronic Control Unit) then could create current signal in mAmp(miliampers) and send it to four crucial components for the system - the EHA(the electro-hydraulic actuator,a unit consisting of a magnet, an electromagnet and a baffle plate) which had to fine tune the engine in each of its phases, the ICV(the idle control valve), the unit which was predicted for the engines perfect idle, the X11(the diagnostic socket) where the duty cycle(the ideal mixture) was adjusted and the X11/4(the code reader) - the socket which from any codes were read if present using an OBD1 scanner.<br />An extraordinary injection system which could be fully repaired in your own garage using a multimeter and a pressure gauge only for its fine tuning, together with some common tools.<br />"Happy Mercedesing"<br />...<br /><a href="https://www.youtube.com/watch?v=UMQ1RpbPG90" target="_blank" rel="nofollow">https://www.youtube.com/watch?v=UMQ1RpbPG90</a>
