Default 2002 Honda 400ex no power please help!!

so I have a 2002 honda trx 400ex I have a new battery new fuse my 2 ground cables look fine but when I turn my key and hold the clutch and press button to start I hear nothing. nothing happens. no lights nothing. but I think I need new bulbs and also my neutral light stopped working like 2 weeks ago for some reason. but this no power thing just started. I was in the woods I turned the bike off took a break but when I tried to turn back on nothing, no wind no lights no sound at all nothing. like I said battery is new I charged it to 100% on battery charger. I took two screw drivers on the solenoid nuts and touched the two screw drivers together I saw spark and I heard it spin or whatever down there. so idk please help!!!

Might have an issue with your start, ignition, llight switch. Is there any damage to it. My grandsons 300ex was lightly damaged and mud got in corroded contacts inside keeping it from trying to start. Will need a meter that reads Dc voltage to clarify any problems.

Check the main fuse, if this blows everything goes dead. Other possibilities are, as LT Granddad wrote, a faulty ignition switch but also a loose live connection or a bad earth on battery frame or engine. If the light bulbs have blown, put a new one in, then at least you know if the "live" circuit has a fault, or if it is confined to the start button circuit. On most Hondas the ignition light has to be on for the start button to work.
