Check this wiring diag.

Join the forum(s) and ask at either of these two sites.

My guess is you have a DC horn but your stator is
only putting out AC. The voltage regulator is only
there to limit voltage to ~+13VAC. You would need
to (float) the ground from the stator and get a
Rectifier/Regulator with a battery or a Capacitor to
act as a current buffer.
I am in the process of SM'ing my 1998 EC250 also.
good luck and hope to see you on the GG groups.
