My stepdad asked me to look at his Honda to see if I could get it to crank after a running kid drivers and left for dead the last year. Of course , I took it home and cleaned the carb, replaced the battery, air filter, and spark plug. I hit the start button ... nothing. The neutral light does not come, I checked and am getting voltage to the switch, not at starter switch. I have a wiring diagram in service manual, only , it does not show where the neutral switch is located. I'm thinking that may be part of the problem or am I even on the right track ? Thanks for any help here .
