Diesel8186

I have a feeling it’s something simple but I’ve don’t know I did take the front plastic off cause it was broke real bad

Thank u I am trying to figure this out as this ATV will seem like a beast

I’ve got a 1986 Honda fourtrax 350 4x4 I’ve bought it off a guy saying it needed a new fuel pump got it working and running but the one way clutch for the electric start was out so I replaced it and now I have no spark or oil temp light at all I can ground out the blue/red and the green wire and it will turn on the light but not the fan any idea on what to check?
