Relay Module At The Rear of The GSC (1) Relay Module. (2) Screws. (3) Tape. (4) Desiccant package. (5) O-ring seal. (6) Connector of the cable.Relay module (1) contains the relays, fuses and terminals that are used in order to operate the external devices of the EMCP II. Relay module (1) is a component of the GSC.Reference: Special Instruction, SEHS9710, "Relay Module - Replace".Replacement Procedure
Remove the positive lead wire from the battery.
Make sure that all of the wires at the terminal strips are marked with the respective termination point. During reassembly, these wires must be reattached to the correct terminal. Remove all of the wires from the terminals and the wires from the posts of the relay module (1) .
Remove ten screws (2) that fasten relay module (1) to the GSC.
Be aware that O-ring seal (5) exists. Partially separate relay module (1) from the GSC. Carefully disconnect the cable clamp and the cable connector (6) from relay module (1) .Verify the small jumper block on the PC board. The small jumper block is near the cable for the ribbon cartridge. The jumper block of the original relay module should match the jumper block on the new relay module. See Testing And Adjusting, "AC Voltage Range - Adjust".
Replace the desiccant package (4) with the new desiccant package. Replace the tape that is included with the new relay module. Attach the new desiccant package in the same manner as the one that is removed.Note: Do not remove the new desiccant package from the protective container until the relay module is installed into the GSC. The length of time that is required to install the new relay module is twenty minutes. Longer periods of time will cause the desiccant package to become saturated with moisture.
Install new O-ring seal (5) in the groove of relay module (1). Make sure that the O-ring seal (5) is seated properly. Align the connector of the cable and reconnect the connector of the cable (6) to the relay module (1). Install the cable clamp.
Place relay module (1) on the GSC. Check that O-ring (5) remains seated. Align the screw holes of relay module (1) and the GSC. Install ten screws (2) and tighten ten screws (2) .
Reconnect all the wires to the terminals of the relay module that were removed. Reconnect the positive lead wire to the battery. If necessary, see the "Generator Set Wiring Diagram" in Testing And Adjusting, "Schematics and Wiring Diagrams".
