where have you plugged the charger in ?
best to be on the feed wire from the regulator, then you're checking for DC volts in the circuits. the horn will sound crap, but it should make a noise.

otherwise, something is shorting to earth somewhere, so recheck that with your multimeter

It's quite posible that your charger isn't man enough to power the headlamp, try the lamp directly on the charger.
