Motorcycle Repair: electrial (turning signals, horn, headlight), kawasaki vulcan 800a, ground wires

Question
My battery on my kawasaki vulcan 800A had died.  I replaced it with a new battery and now my horn headlight and turning signals are not working but the motorcycle is running.  Can you help and advise me what I should check or change to repair my headlight, horn & turning signals.

Thank you

Answer
Sounds like a loose connector somewhere.
Check around the battery for any connections
that are bad or loose. Maybe something
got jarred when you put the new battery in.
There should be 12volts to your flasher,
check it with a test light.
If not, then recheck all fuses, connectors, and
ground wires.
