Ground the MP modem
Note: Electrical installations are potentially dangerous and should be performed by
personnel thoroughly trained in safe electrical wiring procedures for vehicles.
Automotive installations usually provide a good quality ground for each piece of
electrical equipment. In most cases, ground the MP modem by connecting the
black ground wire of the power harness to either the vehicle chassis or to the
negative terminal of the battery.
If a device connected to the MP modem, such as a notebook computer, is not
properly grounded, it may ground itself through the cable connecting it to the MP
modem. This creates a hazard and could cause equipment damage. If you cannot
properly ground a device, a potential solution is to install a fuse in the ground
return wire.
The power harness has 5 A fuses on the red power wire and the white ignition
sense wire, but not on the black ground return wire. (See
power harness
on page 27.)
