(display does not
light)
No power to yellow wire;
no power to red wire
Check connection with test light;
check vehicle fuse with test light.
Inline fuse blown
Replace fuse.
No power to unit
Inline fuse blown
Check/replace fuse.
No speakers oper-
ate (display lights
normally)

nected
Connect speaker harness; check
speaker wires.
Not all speakers
operate
Incorrect splices or con-
nections
Check all splices and connec-
tions.

chassis ground or to each
other
Check splices, insulate all bare
wires.
Blows fuses
Power wire shorting to
ground
Make sure wire is not pinched.
Speaker wires shorting to
ground
Make sure wire is not pinched.
Incorrect fuse/fuse too
small
