TROUBLE-SHOOTING

SYMPTOM

Amplifier cuts off when
driven to high output 
levels. Overload circuit
activated (red LED on).

POSSIBLE CAUSE

Excessive output current is the only
thing that can cause the Overload
LED to light. 

There are only a few

possible causes:

A damaged speaker cable touching
the vehicle chassis, speaker cables or
speaker tinsel leads touching each
other, or damaged speaker voice coil.

Damaged passive crossover 
components.

Total speaker impedance is too low
causing excessive output current.

Defective output transistor inside the
amplifier

SOLUTION

With the speaker wires disconnected from the
amp, use an ohmmeter to check for a short from
any speaker cable to chassis ground. Check the
DC resistance of the speaker's voice coil. It
should be close to the speaker's nominal imped-
ance specification and should fluctuate when the
cone is touched. Visually check each speaker for
damaged tinsel leads, or other broken parts.
Smell the speaker's magnet area for a burned
scent indicating a damaged voice coil.

Visually examine inductors, capacitors and 
resistors for signs of heat stress, water, or 
physical damage. Use a soldering iron to touch
up connections to the crossover circuit board. 
Try substituting a different crossover network.

Re-wire speakers to raise the total impedance
seen by the amp.

This condition will cause the overload LED to
stay lit without speaker wires connected to the
amplifier. The amplifier must be returned to an
authorized service center for repair.
