FUSES AND CIRCUIT BREAKERS

GENERAL
Buell motorcycles feature two components which protect the
electrical system; fuses and circuit breakers.

WARNING
To protect against shock and accidental start-up of vehi-
cle, disconnect the negative battery cable before pro-
ceeding. Inadequate safety precautions could result in
death or serious injury.
Fuse Block
See Figure 7-53. The fuse block contains five fuses and two
spares. Two additional spares may be added at the rider's
discretion.
The fuse block is located on the right side of the vehicle,
under the tail section.
Always investigate the cause of blown fuses before replacing
them. See your Buell dealer for more information.
Circuit Breakers
See Figure 7-54. The 30 ampere main circuit breaker is on
the frame beneath the tail section.
Circuit breakers prevent electrical overload of a circuit. The
circuit breaker electrical contacts remain closed (completing
the circuit) as long as current (amperage) flowing through the
circuit does not exceed the ampere rating of the breaker. If
the circuit current exceeds the breaker ampere rating, then
the circuit breaker contacts open and the current flow in the
circuit is interrupted.
Since the circuit breaker is the automatic-reset type, the
bimetallic breaker contacts automatically close (completing
the circuit) once they have cooled down from the initial over-
load. If the overload condition still exists, the breaker contacts
will again open to interrupt current flow. This opening and
closing of the breaker contacts continues as long as the cur-
rent circuit overload condition exists.
