Re: Electrical Gremlins...
I wouldn't worry about the horn but the lights would be annoying.
Have you tested the relay?
I know on the 929 all three relays (lights, starter and fuel pump) are the same so you can just switch them to confirm if one isn't working.
Since the horn isn't working either maybe you've cut a wire somewhere.
