How to Replace the Fuses
How to Replace the Fuses
If the MCC602TM produces no sound, no Meter
Illumination, the power control and the power
supply connections seem secure, one or more
of the Amplifier Fuse(s) may have failed.
Under normal operating conditions your
amplifiers fuses should not fail. Failure of a
fuse is usually an indication of a problem.
Replacing the fuse, if there is problem in the
amplifier, may incur a risk of further damage.
Refer to figures 7, 8 and 9.
Caution: Disconnect the Amplifier from the
Vehicle Battery ( or DC Power Supply)
as Potentially Dangerous Currents
exist inside the amplifier.
1. Before accessing fuses, disconnect both the
positive and negative power cables from
the DC input terminals on the left side of
the amplifier using a 5/32 hex key.
2. Remove the Top Glass Panel by first
removing the eight hex bolts with the sup-
plied 3/32 hex key.
3. Attach the supplied suction cup to either
side of the top glass panel and carefully
raise it high enough to put your hand under.
Temporarily place the removed glass panel
in a safe place, remove the suction cup and
save it for future use.
4. Remove the Phillips Screws holding the
End Caps on both sides of the amplifier
and lift the end caps off.
5. Remove the fuses with needle nose pliers,
taking care to avoid hitting the wattmeter
during removal. Do not lever the pliers
against the wattmeter.
Note: To determine if the fuse has failed, examine
the link between the two fuse legs to see if
it has a break in it.
6. Replace the fuse with one of the same type
and rating as unauthorized substitutions
may prove hazardous to you and the
amplifier.
7. When reinserting the fuse, set it in place
with the pliers, then push it the rest of the
way in with your finger to avoid having the
pliers slip and hit the circuit board.
8. Reinstall the Top Glass Panel.
9. Reconnect the power cables to the vehicle
battery.
If the replacement fuse(s) fails again, have the
amplifier repaired at a McIntosh Service Center.
