Main fuse keeps blowing and now no spark at all

[King Nothing]

I have a FXR150 thats decided to die on me... It started having problems after heavy rain....It started with the dash disply flickering and then dissapearing completly.. I found that the negative terminal was loose so I tightened it and it seemed to fix the problem.... however this was not so as when I went to take off the bike stalled before I got to the end of the driveway and I lost the ignition again... After checking all the other connections around the battery I discovered the main fuse was blown... I replaced it and it blew again... Thought it may be the alernator, so i disconnected it and replaced the fuse.... same result.. blown fuse... disconnected the battery.... kicked it over.... no blown fuse.... replaced battery... blew fuse.... checked earth connections from battery to body... now no spark from coil (checked by removing lead from spark plug and using a screw driver and watching for spark to 'jump' across to the body) .... anyone have any ideas?

Sounds like your electrical system is earthing out when it shouldn't. You will have to look at all the connections and tighten them, make sure they are not shorting. Check the battery earth lead make sure this is connected to the frame and not rusted.

Basically, you will have to start at the battery and work your way along the whole system. Unless you have done something to the bike and can start there.

Fuses are your friends as they will prevent the next electrical component in the circuit being overloaded and blowing. A fuse is cheap. So do not hard wire the fuse (do not bypass it).

All good... I decided that if there was a problem with the electrical system there must be something not working properly.... so after a bit of inspection i found that the fuse was blowing when I used the front brake... It turned out that the wires just needed a little bit of attention and now all is good...cheers for the help bud!
