HELP PLEASE - All electrics gone

Amazoner · Dec 27th, 2013, 15:11

hi all,

I have a 1967 121, with an ignition switch that is used to switch the car on, and a push button to start the car, installed by a previous owner.

In the morning I started her up fine, filled her up with petrol, parked her outside (no rain) ready for a nice long drive. Two hours later, I switch her on and absolutely no electrics working at all - no instruments, no lights nothing.
But when the key is in the on position - she still starts and runs perfectly well, using the push start button.

My immediate thought was a fuse, but checked the fuse box and all was fine.

My next check was the battery terminal, but given she turns over perfectly well, I can't imagine that would be it. I did loosen and retighten the terminals.

My worst fear is the ignition switch has failed and needs replacing, but why then does the start button start the car when in the on position?

I understand that if one electrical component goes, it could affect the everything, so I guess it could be anything.

If anyone can give me advice on how to solve it or where to start looking, i would very much appreciate it.

Thanks all,
