Actually, I've never worked on any different voltage
systems except very little on 6 volt syatems. The
word
in the business is that we will be seeing electrical
sytems on cars of the future that will be of much
more
voltage than today, maybe up to over 60 volts but at
least 48 volts. This is due to the increasing number
of electrical consumers on modern vehicles. I
wouldn't
use a 6 volt relay on a 12 volt system. I would think
that the only difference in these relays is their
current handling ability; and remember that according
to Ohm's law that all other things being equal,the
more the voltage, the higher the current. Now whether
due to this, the trigger coil of a 24 volt relay
would
require a higher current to operate (create enough
extra magnetism to pull down a heavier and stiffer
set
of points), I don't know. But, it wouldn't hurt to
try
a 24 volt relay as it wouldn't hurt anything, just
wouldn't work. Although, it might defeat the purpose
of the relay by requiring more current to operate
which in the case of these starter problems, is the
problem to begin with. Conversely, the 6 volts are
going to be less robust and may not be able to handle
the extra current of the 12 volt system. I know of 6
to 12 volt conversions where all you had to do was
change the light bulbs as they would "blow out" with
the higher voltage. I think they also changed the
generators to 12 volt so there would be enough output
to charge the 12 volt battery. These 6 volt cars were
before alternators, although you could adapt one of
those, too. The safe bet is to use the same rated
relay as your system.
