DC/DC Power Supply with Screws on Side of Lid
Inspect the cable shield to verify it is connected to chassis ground. If there is no connection from the cable
shield to chassis ground, one must be added at this time. Use a jumper wire to connect the cable shield to
chassis ground as shown below for the appropriate type of power supply installed on the vehicle. A jumper
wire, as shown in the illustrations below, may be present to attach the chassis ground to the white wire of the
power cable. This wire is not necessary but can be left in place if present. For proper screen blanking, verify
the yellow and green wires are attached to the screen blanking box as shown in the illustrations below.
For this model, follow the diagram below to attach the power cable shield to chassis ground:
