Eletrical wirings

Many thanks Norbert
/David

Hi Volker, Nober and all
I found out that the wiring diagrams in the "handbook.w116.org" where really good, wery helpful.
But I have one question about a 2 plinth socket/connection near the 2 pre-resitors 0.4 ohm and 0.6 ohm, near the ignition coil.
I really cannot find the connection in the wiring diagrams. Maybe I'm blind. I want to know which are all the cables to this socket. And where do the go from there. One of this cables was lose and hit the ignition coil and the alternator was to be repaired. This one goes under the fuses in the fuse box and in under the dashboard. (maybe 15 start-run bus?) But again I want to know all of the cables to this connection. Maybe the connection can see a little different in w116 compared to the w107. I will try to send some pics.
Many thanks if you guys out there can help me.
Regards David

No, I think the pictures are to big, I'm afraid.

Hi David,

that is well documented in chapter 07.5-519 General description of breakerized transistor igntion system of both R/C107 and W116 workshop manual. Just click on 107 SL Workshop manual above . Then look at section standard TSZ switchgear - standard switchgear on page 6. 15 comes from starting switch and "a" from starter itself. "a" bridges first preresistor to increase starting voltage on ignition coil.

Thanks..
.. if I look at page 6 it look like my connection, with one cable connected direct from switchgear to the ignition distributor. But then I don´t understand my cable that goes from Terminal 7 and disappear under dashboard. That one that cause my shortcut. Because in page 6 there is only one cable connected to terminal 7 and that one goes to TD in switchgear. What is "V" in the picture?
Sorry for being stupid

Hi David,

V means voltage measurement for testing the ignition module and coil.

pin 7 on ignition module is the green shielded cable with coax type connector at ignition module. It must go drectly to ignition dustributor. Pin TD on ignition module goes to an rpm meter (Americans call it tachometer which we would use for speedometer) in your dashboard - if you have one.
