4001 Fox Run Road Powhatan, Virginia
Often six volt batteries to run buzz coils are not available.
Although twelve volt batteries are more readily obtained and seem
to work fine, they will destroy the points and could prematurely
cause coil burnout. By installing one two-ohm resistor or two
one-ohm resistors at ten watts in series with one twelve volt
battery lead, it is possible to reduce the input voltage to eight
or nine volts, a more acceptable value for the Model T buzz coils.
The resistors can be purchased locally at your Radio Shack or radio
parts store.
Once the resistor is installed in the circuit, adjust the
tension nut on the buzz coil to allow the coil to produce the
highest pitched tone. This will produce the hottest spark possible
from the coil.
