This is for my 1979 240D W123
After a week of misdiagnosis documented in this thread:
Ignition or tumbler or switch or ???
I think it is a grounding problem.
For the fun of it, I replaced the #5 fuse, disconnected then reconnected the battery.
Result:
All lights that are supposed to go on are on (dash, glow, dome, etc).
After the glow plug light goes off, I turn to crank, then nothing - everything goes dead.
No lights, no ticking sound of the clock, etc.
When I went to disconnect the battery, I hear a faint humming, electrical
like sound, like maybe from the cd player? But I can't tell for sure, since I am under the hood.
Because I was touching the battery connecting the terminal, I fulfilled the ground function?
What say ye W123 gurus?
And be easy on me, I'm just a girl...
