7) Connect the power cable black lead (with ring lug attached) to the vehicle's
negative (-) battery terminal, or to the jump start block on vehicles so
equipped.
Caution: Avoid disconnecting the battery-to-engine block ground, which
might damage the vehicle and/or radio. An in-line fuse (not included) may be
installed near the battery in the black lead. Use a 10 A fuse for RPM-150 or
RPM-450 installations, a 20 A fuse for the RPM-050.
8) Connect the fuse assembly lead (ring lug attached) to the positive (+) battery
terminal. Check that the fuse assembly contains a fuse. Use a 10 A fuse for
RPM-150 or RPM-450 installations only. DO NOT use a 10 A fuse for RPM-050
installations.Instead, use a 20 Ampere fuse.
Important: Failure to connect the power cable red lead directly to the battery
(via the fuse) can produce severe alternator noise in the radio.
