Separate switch to crank the engine?

When the ign. is in the crank position, source voltage from terminal 30 connects to 50 (yellow wire). This yellow wire energizes the starter solenoid. Sounds like the "crank" or "start" position in the ignition switch is NG. It happens.

There's normally no relay for the start circuit on these MY cars.

Sounds like the PO may have disconnected the yellow wire at some location because of the malfunctioning ign. switch, then installed another 12 volt source wire to energize the separate starter switch and relay circuit to energize the starter solenoid.

That sound about right?
