Duetto electrical problems

[Dan Walker <dawnanddan@domain.elided>]

Hi everyone,

I have a vexing problem with my Duetto. A couple weeks ago I discovered 
that I had no high beams ( I have Hella lights with H-4 bulbs 60/5 watt 
hi/lo ).  The fuses were okay but both high beam filaments were burned 
out.  replaced both bulbs and everything tested okay.  Took the car to work 
during the day, flashed the high beams to pass someone.  Later that night 
got in the car and NO HIGH BEAMS !  Low beams okay. All other electrical 
okay ( so far ).

Took the car again and tried the horn.  It gave one short blip and quit.  I 
tested the voltage to the headlights with the car running at about 4000 
rpm.  Got 12.7 v at the low beam and 14.8 v at the high beam.  The horn 
relay clicks but no voltage gets to the horns.

Do I have a bad voltage regulator ?   Also, does anyone know what size 
fuses go where because the owners manual doesn't say so.

Thanks,

Dan Walker
