2000 big bear 400 no spark

Alright guys. I am stumped on this thing. When I turn key on it has no neutral light or oil light. I have power to headlights when the key is on and no headlights when the key is off. When I turn key on it does nothing. No relays click or anything and No spark when I jump starter solenoid. Starter solenoid is brand new. Any help is appreciated. Need to get this bike running ASAP

    Probably a bad coil or CDI box.

    Is there a way to check the CDI or the primary coil?  Would the primary coil being bad keep the neutral and oil lights from coming on? How do i check the neutral switch?

    Get you a service manual. You can check a coil but I think that is not your problem since you say your lights are not coming on. To check neutral switch you need a volt meter and set to ohms. Get across the two electrical pins for it and actuate the switch. The meter should go from OL to some ohm reading.

    I found a schematic and tested all the sensors and such and had no luck. I also found a melted ground wire in the harness. It's melted from the ignition coil to the last spot where they join more wires in and go to frame ground then the cdi. Would this cause it to keep burning up cdi's? This will be the second one I've had to put in it for the exact same reason and they aren't too cheap.

    Alright yall I changed the cdi and it still does nothing. No relays click or anything. And no lights come on. I cleaned all the connectors and put di-electric grease in them. What do the 2 relay looking things do and also the small black block (not voltage regulator)
