Hello all, I’ve used this forum as a resource for information on my Mercedes cars for years. This is my first time posting!!
I just purchased a fairly decent 1989 190E 2.6 not running. PO told me no spark and that they have replace the ignition coil. At the ignition coil I have found a lead with an eyelet that belongs on a stud or bolt but I do not know where it belongs or if this coil is even wired correctly. Also, if the CPS is good shouldn’t I see the tack register engine speed while cranking. TIA

I’m trying to attach a photo currently of the wire in question but mobile view isn’t working for me and I’m trying to figure it out otherwise!

Finally figured out how to upload photos!!!

Brown wires are ground wires. Clean off the eyelet, find a screw that goes into the chassis sheet metal, clean under the screw (bare metal), and ground that wire.

Ok, thank you very much. Brown wire is indeed a ground, I was getting 9v at that wire through Fluke multimeter so apparently I have a bad short back feeding somewhere or it was a fluke(pun intended). Now I have a dead fuel pump relay. Should I start a new thread for help with that?

Rand190E, send me a PM.
