Hi can you tell me what the voltage is from from the green wire that is from the spark amplifier to the distributer. I have checked the coil and changed the spark amplifier but still have no h.t.spark from the distributer can any one help. walter.

Hi Walter - are you able to post a picture of the wire(s) that you're referencing? May be easier to address if it was visible. Thanks!

-Dmitry

ws:

If the ignition system has points in the distributor, the voltage in the trigger (green wire) circuit will be about .3V.

If the system is breakerless, with a magnetic pulse generator (VR) in the distributor, the pulse will vary between .3 - 100V, as a function of the rotational speed of the distributor rotor.

Dmitry - He said he had a 1983 380 SEL. Wouldn't be a W126 with M116 engine? Don't you have pictures of the distributor and the green wire he is referring to right here on your own site?

He wants to know what voltage he should see.



Walter Senior - Your car likely has same engine as a 1983 380SL (116.962) MBUSA on their Startekinfo site has the full shop manuals.
You might want to check out the section on the ignition system.
Full Manual: https://www.startekinfo.com/StarTek/outside/11883/PROGRAM/83380sl.html
This is from Section 15 (ignition):

By the way - I know next to nothing about that system

And sorry picture came out so large - just pasted link from Pelican How-to area.
