R107 1983 Starting Problems

[andydent]

I have an R107 SL500 that has been running fine until refently. Now when I come to crank the car I get a click then the entire dash dies.
If I remove the battery after a couple of tries I get the ignition back and can hear the fuel pump. Try to crank, clunk, no power. I am guessing there is a relay or something? Can anyone point me in the correct direction.

Been a while since I have played around with this vintage but I would suggested looking into your OVP relay if nobody has any better ideas

OK so I have now changed the battery (existing was less than a year old) but yes it proved to be faulty. So now I have a engine that will crank and missfire - run for a few seconds - then die. Ho hum - more work needed.

Loose battery connection on the earth to chassis or positive to starter?

The relay on my 2003 c180 komp was in the boot. Hidden behind the medical kit panel.
