#1 Find what is blowing the fuse... Neutral switch can still work---just no visual indication.
Speedo, front running light, temp/oil/neutral lights, tach, tail light, license plate light all on the
Black/Brown wire. You do anything on that wire?? Any adds or changes????
Neutral switch puts out a ground---cannot blow a fuse---also sends a signal to ECM. ECM has to see a ground to run in neutral. This same "ground" to the ECM also goes to the "Starter relay" so you can crank the engine. IF it does not crank in neutral than there is a problem.
Kickstand switch(UP) puts out a ground--sends a signal to ECM, engine will die if kick stand goes down in gear. ((OR if kickstand bolt loose, damaged or wiring problem)).
This same "ground" from the kickstand switch goes through the clutch lever switch when you pull the lever to allow cranking in gear.
