We understand that, but you do have to take some initiative and use common sense/logic in learning, do not sell yourself short!
obviously you just lack self confidence.
look at the wiring diagram it is just as simple as water flowing through a hose or many hoses.
The power comes from the ignition switch then through safety switches, eventually to the solenoid switch,---- somewhere it has lost its continuity.
if you follow it and say it goes to a clutch switch, it should show up as 12V into the switch and with the clutch pushed down it should also show 12V coming out of the switch. if not, it is obviously a problem switch.
If power does flow through the switch it is ok and you need to go to the next path it travels on, where you no longer see 12V, that is the "broken" link in the circuit!
It is really simple and you are just working on the starting circuit, not all of the wires/circuits.
We will help you but you have to do your part, as we physically cannot.
