Make Ground Connections at Fuse Block and Time-Delay Relay
1.
Strip one end of the 10-AWG black wire (included with the Fuse Distribution Rail Kit) and crimp a
3/8-inch ring terminal to it.
2.
Near the Fuse Distribution Rail Assembly, locate an area of vehicle chassis ground within one foot of
the assembly and strip the area of any paint or dirt to expose a bare metal surface.
3.
Drill a hole as necessary and connect the ring terminal to chassis ground. Use a self-threading screw
or other appropriate hardware to ensure a reliable metal-to-metal contact. Tighten securely.
4.
Cut the black wire to a length long enough to reach a green-yellow Grounding Block on the Fuse
Distribution Rail Assembly, plus length for a service loop. Strip the end and connect it to a
Grounding Block in accordance with the instructions provided with the kit. Adjacent Grounding
Blocks are electrically connected together, so the black wire will ground both blocks.
5.
Obtain the radio’s DC Power Cable (Item 3 in Table 4-1) and temporarily connect it to the radio.
Next, cut its black (negative) wire to a length long enough to reach a Grounding Block, plus length
for a service loop. Strip the end of the wire and connect it to a Grounding Block in accordance with
the instructions provided with the kit.
