W110 230 Starting Problems (Electrical)

I have a 1967 230 that is having some electrical issues. When I turn the key to start the car it starts up then dies when I release the key, if I leave the key in the start position the engine continues to run until I release the key. It will stay running if I hot wire the coil. So the coil is not getting power in the run position, but is getting power in the start position. The car ran when I parked it 10 years ago. Would this be an ignition switch issue, or a wiring issue? Is there a wiring diagram available online?

I am not sure if the car has transistorized ignition, but I believe that one of the resistors is bypassed during cranking. Perhaps your resistor is bad.

Indicates a faulty bypass resister which can be checked for voltage on both ends, ignition on or a continuity check.
On my 230/110, I had replaced points with a Pertronix unit and still find it reliable,gives smoother idling and running .

Could be the ignition switch behind the key too.

I have a similar car, and when I bought the car it had an aftermarket toggle switch installed that had to be turned on to get the car running. I think the switch is connected to the coil. It works in my car, as is, so I haven't troubled it.

It ended up being the ignition switch. The electrical part was loose, so when I let go of the key the internal spring would stop at the 1 position instead of the 2 position.
