SERVICE
The complete system consists of the amplifier, speaker, and switch panel components along with
the wiring and electrical connections. A blown fuse on the amplifier does not necessarily
mean the amplifier is bad. If the system stops functioning or exhibits problems, first check that
the wire and electrical connections to each component are OK then check the following.
the wiring and electrical connections. A blown fuse on the amplifier does not necessarily
mean the amplifier is bad. If the system stops functioning or exhibits problems, first check that
the wire and electrical connections to each component are OK then check the following.
On the switch panel, check for power into (center terminal) and out of the switch. On the HORN
SELECT switch, check for power while pressing the horn ring. If there is not power into the
switch, check wire for bad connections and check fuses or breakers in the circuit. If there is
power into but not out of the switch, the switch itself may be bad.

While activating the amplifier (with horn ring), look for the output indicator to light up. If it
lights up the amplifier is OK. If not, check the fuse on the amplifier. If the fuse is OK then check
the POS and NEG power input leads for good supply and ground connections. If power into the
amplifier is OK then check that the voltage level at POS and NEG on the amplifier is less than the
rated voltage. If the voltage level is OK then the amplifier may be bad.

If the fuse on the amplifier is blown, disconnect the speaker leads at the amplifier and replace
the fuse. As before, activate the amplifier and look for the output indicator to light up. If the fuse
blows again then the amplifier may be bad.

blows again then the amplifier may be bad.
If the output indicator on the amplifier lights up, disconnect the leads at the speaker and
check the speaker inputs with an ohm meter. If the reading is less than 1 ohm or reads as open
circuit then the speaker may be bad. If the ohm meter reading is OK then the wiring or connec-
tions between the amplifier and speaker may be faulty.
The following chart shows typical symptoms and possible causes.
