common, confirm that the installer has connected the power
and ground wires through the firewall directly to the vehicle
battery.
Grounding ONLY to the car frame or a terminal is not
acceptable for reliable DV-1 operation.
The Intelligent Uninterruptible Power Supply Battery (iUPS) may
require additional charge or may need to be replaced.
Check the fuse in the ignition (switched) power wire. Check the
settings in
Set System Behavior on page 78.
