(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) Speaker harness not con-
nected Connect speaker harness; check
speaker wires.
Not all speakers
operate Incorrect splices or con-
nections Check all splices and connec-
tions.
Speaker wires shorting to
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 Install fuse of correct rating.
CD skips too much Receiver mount is not
solid or backstrap is not
secure Check mounting and backstrap,
tighten if needed.
