Title: Ground wire location
Post by: dpreston Virginia on May 02, 2024, 20:07:16

Ground wire location
I just had some work done on my 69 280SL and there is some question on the location of the ground wire that is attached to the support to the relays near the battery.
Please take look at the photo and tell me where the other end attaches. The arrow shows the wire.
Thanks for any help.

If memory serves me well, goes to one of the radiator holding screws. Part of creating Faraday’s cage for interference suppression.

Discussed here on Forum, would come out in a search.

Pawel
Did a few searches and no luck. So if someone can help with the location of the end of the ground wire in the photo I would much appreciate it.

Maybe I looked at your picture too quickly. There is a ground wire from location on the engine next to distributor (that is what I though you were asking) and this one goes to the radiator holding bolt.

If you have a strap attached to relay bracket, well, I do not know, perhaps goes down to the transistors unit under the battery...
