Disassembly and Reassembly
16 - 29
Injector Head - Cable
Head Cable Removal 1. After disassembly of the injector head, note the routing of the cable
wires, then remove any cable ties securing the main cable to the
cable bracket or any other parts of the injector head.
2. Remove the clamp securing the main cable to the bracket, and set
aside until installing the replacement cable.
3. Carefully remove the motor leads (two on each terminal).
4. With a medium-blade screwdriver, remove the screw securing the
ground ring terminal to the back casting.
5. Disconnect the connectors from the head card at P/J55 and P/J27.
6. Disconnect the connectors from the TEC Card at P/J71-73, then dis-
connect the LED by removing Pins 9 (black) and 10 (red) from P71.
7. Carefully lift the cable from the injector head to avoid disturbing other
wiring.
Head Cable
Replacement
1. Position the replacement cable in the injector head. Route the four
wires with push-on connectors (two wires in each connector) to the
motor. Refer to Page 20 - 24 for proper connections.
2. Connect the head card connectors at P/J55 and P/J27.
3. Remove the jumper header between P72 and P73. Connect P72
(front) and P73 (rear) to the TEC Card with “THIS SIDE OUT” facing
away from the card. Install the BLACK LED wire in Pin 9 and the
RED LED wire in Pin 10 of P71.
4. Position the cable on the bracket, then replace and tighten the
clamp.
5. Secure the ground wires with the mounting screw previously
removed.
6. As necessary to prevent interference with any moving parts, install
cable ties securing the cable and other wires to the bracket.
7. Apply power, then check injector head operation.
8. Reassemble the injector head. (See the procedure on Page 16 - 13.)
