Wont start Got power to and thru start switch wont start. Neutral saftety? Maybe? If it is where and how do I repair it

Need more information than "won't start" ie is it clicking, nothing at all, turning over but won't start etc. Neutral switch is a neutral light switch, is the neutral light on? If the Motorcycle is in gear the clutch lever must be pulled in. If it is an HDI model is the Jiffy stand down and the transmission in gear ie are you in neutral or in gear with the kickstand down etc. ???

Here are possibilities:

If the starter motor does not operate or does not
turn the engine over is the engine run switch in the OFF position; is the Ignition switch in the IGNITION position which it needs to be; is the battery discharged or are there loose or corroded connections in which case likely the solenoid will be chattering; is the starter control circuit, relay, or solenoid faulty, (need to go through each element); OR is the starter shaft pinion gear not engaging or is the overrunning
clutch slipping; OR is the TSM/TSSM/HFSM Bank Angle Sensor tripped and the ignition switch has not been cycled OFF then back to IGNITION position OR is the Security system activated in which case it will have to be de-activated.
Do other electrical systems work such as horn, lights etc. If not maybe the Main fuse is blown or not in place. Is the battery installed wrong/backwards. Is the ground underneath on the transmission case properly installed, clean and tight etc.
