87 W124 260E central locking suddenly stopped working. Voltage on the 2 pin plug at the Central Locking pump measures 5.6 Vdc. The soldered wires on the bottom of the pump PC board, which I think comes from the Alarm System also measures 5.6 Vdc. Should these be at 12 Vdc ? Any ideas as a solution ? Does anyone have a complete Central Locking wiring diagram ?

 

Drakes Go to google search page look up to the righ of the page and click on images .
Then in that search box put Mercedes Central locking diagrams.
Then you choose for hundreds on there.
