Hal

Hello all Hi my name is Hal and I'm 66 years old and own a Bultaco Alpina #116. I have been riding since 1971 and have owned the Alpina for 3 years. I am in the process of rewiring the headlight, taillight. The model year is 1974 and it has a Lucas hi-lo/ horn button combination switch. The headlight is also a lucas unit with red high beam indicator. I have run all new wires on the machine the resistor and diode tests good. Does anyone have a schematic for the headlight? There was also a small lucas diode bolted to the inside of the headlight bucket and that tests no good, was this diode original or did somebody add it in? Also the bike is still on points and condenser I am familiar with lucas wiring and know which wires are Hi and Low. I am trying to get it legal so I can register it, I certainly would not entertain riding at night with a 6 volt headlight. Thank you for any help or insight that you may have. Thank Hal in CT.
