The murray riding mower I have will not all even crank. In the wiring system from the wiring harness to the alternator wire the connecting wire has 3 wires and one of those wires is black which would indicate that might be a ground but I'm unsure of where it goes. Any help is greatly appreciated. Murray riding lawn mower model #309029X92C

Try searching on line for a wiring schematic .
I have a older schematic but having a brain moment that keeps me from posting the pic .

my problem is my brain does not work as well when I was in my 20s even though I have looked at wiring diagrams and solved them but now I can not tell origin for anything anymore

Good luck with finding the correct Wiring schematic! If you are referring the the BLACK at the motor connector; it goes to the terminal on the coil for the "Engine Stop Circuit". The Murray I have been working on has been a real PITA! I finally made my own wiring diagram

still doesn't show my connection which what I not seeing in the manual for the motor and murray chassis wiring harness doesn't show up. the dual alternator connector has 3 wires one is black but unsure where it goes.

You will have to remove the top plastic cover on the motor. At the flywheel you will see the coil, and underneath it a small "tab" This is where that black wire attaches.

that's already been attached

the wire I'm talking about is the one that goes from stator or alternator out to the chassis wiring harness cause the alternator is a dual charging system.
