Installation.
Tag and disconnect electrical leads to CONVENIENCE RECEPTACLE (20), GROUND FAULT CIRCUIT INTER-
RUPTER (23), and connector to malfunction indicator panel (27).
Tag and disconnect electrical leads to all indicators, switches, and lights on control panel.
Remove screws (13 and 17, FIGURE 4-1), nuts (14) and (18), caps (16) and (20), diagnostic connector (15), paral-
lel connector (19), and gaskets (21) and (22) from control box panel.
Remove screws (23) and nuts (24) from harness connectors and remove harness assembly (25) from control box.
Inspection.
Inspect control box harness wiring for breaks, damaged insulation, and loose or damaged terminals.
Inspect harness connectors, sockets and terminal boards for cracks, corrosion, stripped threads, broken pins, and
other visible damage.
Testing.
Set multimeter for ohms.
Check individual wires, connectors, and terminal boards for continuity. Refer to Wiring Diagram FO-2 for wire iden-
tification.
Repair.
Replace damaged cable assemblies, terminals, connectors, sockets, and terminal boards.
Replace or ensure proper connection of all wires not indicating continuity.
