lighting question on a 1973 f7 kawasaki

 

hi,
i read on my wiring diagram that if my headlight burns out i will lose all
other bulbs due to power spike?i have a 1973 f7 175 kawasaki and it uses a
sealed beam 6v 35w/35w and also ask if it can be upgraded or converted to
use a standard replacable light bulb ease of availablity and cost.strange
thing is the wiring diagram makes reference that the power supply to the
headlight is ac not dc...does this mean i must buy 6v ac lighting on my
motorcycle?anyways if anyone could help me understand a little better or
has a solution for dumping this sealed beam unit i'm all ears,sincerely
ted

Yes, I had that happen on a Yamaha once. I didn't believe it could
happen, and then I had to buy a bunch of new bulbs.

Smaller motorbikes of that era had what was called a "balanced"
charging system. There was no voltage regulator. The light bulbs did
the regulating.

The light bulbs provided exactly enough electrical load to use up all
the electricity coming from the lighting coils. The lighting coils
weren't passing any electricity until you turned the headlight switch
on. If the headlight burned out, your tail light and brake light would
burn out very quickly.


Check the online catalog a www.denniskirk.com to see if you can find a
headlight reflector that takes a bulb to replace the sealed beam.
That's what you would need. If you should need to replace the sealed
beam, it would have to be a motorcycle sealed beam, as the lens is
different from sealed beams used on cars.

There are no such things as AC or DC incandescent light bulbs. They
work on either. Headlights don't know AC from DC since it's a resistive
load either way.


It's a very old motorbike, you might try googling for forums that talk
about older enduro style Kawasakis. Maybe somebody has a parts bike you
can buy or wants to sell parts.
