T-top Fuse Block
Main 12 VDC power circuit 5 of 6 provides power to
the fuse block located inside the T-top electronics box.
This circuit is protected by one 60-amp, push button
breaker. The 60-amp breaker is located inside the
control console within seven inches of the house bat-
tery OFF-ON switch.
One Group 27 115 amp hour, deep cycle battery nor-
mally powers this circuit through the house battery
OFF-ON switch.
Ten branch circuits can be connected to the 12 VDC
electrical system at the T-top electronics fuse block.
The T-top electronics fuse block also has ten connec-
tion points for the negative side of the 12 VDC electri-
cal system. Some of the electronics might have been
installed at the factory.
If the 60-amp breaker trips electrically, troubleshoot
the power circuit and its protected devices before you
reset the breaker.
Turning the house battery OFF-ON switch to the OFF
position at the end of your mission will cut power to the
T-top electronics fuse block.
See Wire Color Chart in this section for wire colors.
!
CAUTION
The total combined amperage ratings for all
accessories connected to the T-top fuse block
must not exceed 60 amps. Overloading the T-
top fuse block might cause repeated tripping of
the 60-amp breaker and other electrical
problems.
