Circuit Operation
Voltage is applied at all times through the EB-2 HORN
fuse to the horn relay in the alarm and relay control unit.
The circuit continues from the horn relay to the SRS coil
assembly and the horn switch.
When the horn switch is
closed, the circuit path is completed to ground and the
horn relay energizes. The relay contact closes and bat-
tery voltage is applied to the horn. The horn sounds.
