which ground won't make any difference, Just use the meter to confirm that they are both providing good continuity to the frame/ground
tail light works off the battery, so does the brake light
headlight has it's own circuit from the magneto
NOW here is rock meets the hard stop
this moped has NO seperate voltage regulator
everything has to be connected and be correct or you will get high voltage somewhere it is not supposed to be when running the engine at street speeds
this means a good battery, good diode , solid conections for the battery to the charge diode and frame ground, also a good headlight that is connected and drawing power ( turned on ) and good wiring connections thru out the complete bike
you need to use the volt meter on the battery when the engine is running to confirm that it is getting about 7 volts on the battery for charging.
the headlight and the battery balance the magneto/alternator output
if either is not right the other one will be damaged
NO headlight means the battery will get overcharged and run out of water depending on how long it is run that way
no battery means the headlight and main 6volt power circuit will go to high and burn out bulbs.
sound like the horn is just plain bad, any 6 volt small moped/scooter horn can be wired to the curcuit.. to replace the bad one.
or do like i did and get an 'air zound' air horn..
