Warning - Buell S1 Lightning Workshop Manual

FUSES AND CIRCUIT BREAKERS
GENERAL
The S1 Lightning features two components which protect the
electrical system.

WARNING

To avoid accidental start-up of vehicle and possible
personal injury, disconnect the battery cables before
servicing motorcycle. Always disconnect the negative
cable first. If the positive cable should contact ground
with the negative cable installed, the resulting sparks
may cause a battery explosion producing personal injury.
Fuses
See Figure 7-44. Four replaceable fuses are located in the
fuse block on the right side of the frame. A spare fuse is
attached to the fuse block.
The ignition, lights and accessory circuit breakers are each
rated at 15 amperes.
Always investigate the cause of blown fuses before replacing
them. See your Buell dealer for more information.
Circuit Breakers
See Figure 7-45. The main circuit breaker is on the frame
beneath the tail section. The main circuit breaker is rated at
30 amperes.
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 breakers are of 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 cycling effect, or
opening and closing of the breaker contacts, continues as
long as the current circuit overload condition exists.
