78 Dodge PW, w/ 360.
Original problem that alt was no charging.
Installed new alt. Did not help.
Changed regulator & starter solenoid at same time.
It charges now, but engine will not shut off until it runs out of gas.
Pull off positive battery cable, still runs.
It has toggle switch for power to ignition & electric fuel pump.
Used to shut off at toggle switch till I change both parts.

What have I done?

Thanks, SLD
