Replacement Of The Relay ModuleThe Rear View of the GSC+ (1) Relay Module (2) Screws (3) Tape (4) Desiccant Package (5) O-Ring Seal (6) Cable connectorRelay module (1) contains the relays, fuses and terminals that are used to operate external devices of the EMCP II+ system. Relay module (1) is a component of the GSC+.Reference: Special Instruction, SEHS9710, "Relay Module Replacement".Replacement Procedure
Remove the positive lead wire from the battery.
Make sure that all wires at the terminal strips of the relay module (1) are marked with the respective termination point. During reassembly these wires must be reattached to the correct terminal. Remove all wires from the terminals and posts of 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 cable clamp and cable connector (6) from relay module (1) .On the PC board of the original relay module and the replacement relay module, check that the small jumper block (near the ribbon cable) is the same. See Testing And Adjusting, "AC Voltage Range - Adjust".
Replace desiccant package (4) with the new desiccant package and tape that is included with the replacement relay module. Attach the new desiccant package in the same manner as the one removed.Note: Do not remove the new desiccant package from the protective container until immediately before it is installed into the GSC+. Installing the replacement relay module should take approximately 20 minutes. Longer periods of time will cause the desiccant package to become saturated with moisture particularly if in a humid environment.
Install new O-ring seal (5) in the groove of relay module (1). Make sure that O-ring seal (5) is seated properly. Align and reconnect cable connector (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 and tighten ten screws (2) to 1.70 0.25 N m (15 2 lb in).
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".
