8042 Ignition/Main Relay

I have always had trouble with my machine starting with ignition. Starter will always click but most generally not engage. Now my ignition feels messed up and hard to turn with key and also will not at all actuate the starter. When I turn the key over, my neutral relay makes a soft horn/buzzing noise and 40 amp fuse gets hot.
