I have a relatively good shape w200 i bought because original owner couldn't get it started again now i didn't immediately know what was wrong but he had replaced everything to do with ignition as in new distributor new ceramic voltage regulator new ecu u name it so get it home realize that control module has 5 wire plug module has 4 pins so fast forward a year now i cant get it to turn over unless i jump the starter im so busy with work i just don't have time to chase it just wondering if someone out there can give me a place to start im getting 12v on 3 legs of ceramic reg and 5.4 on the other leg
Any help would be great thanks
