Could it be a ignition switch or safety switch.

Yes
the ground wire is open circuit to run & closed circuit to stop
So you have to trace the wire back to find the faulty switch or short to ground
I find it easiest to clamp one lead of a test lamp to the battery + then probe to find a ground which of course illuminates the test lamp

Thank you,I started by the magneto to check for spark,The ground wire attaches to a central location on side of engine and from there to solenoid.

Yes along the wiring especially if the kill wire run behind the starter as that is one place they get pinch when someone replaces the starter and don't pay attention to the wires.

Hello Star Tech and Thank you for everything, did a little finessing on the Snapper 281223BVE.now the mower doesn't crank, check the ignition switch and the solenoid and this what l have going on.I have 12.89 voltage at solenoid connection and also at the starter connection.could the switch and solenoid be bad.

Also checked the wire at the magneto connection no cuts.
