First thing to do with any electrical gremlins is check your plenum chamber to ensure it's dry. Test your battery and check its terminals are fitted correctly.

If you've moved the fuse box out of the way you may have disturbed something in the process so check all connections thoroughly. You may have to unbolt the FB and move it again to do this. There is a seam on the chassis behind each headlight that is known to fray wires (more commonly on the OS) - check the wires around this area are in tact.
