17-6. ENGINE COOLANT HEATER COMPONENT BRACKET MAINTENANCE (Contd)
6. Remove nut-assembled lockwasher (30), screw (34), and resistor (32) from resistor holder (31).
7. Remove four screw-assembled lockwashers (29) and receptacle (28) from heater component
bracket (9). Discard screw-assembled lockwashers (29).
8. Remove nut-assembled lockwasher (27) and resistor holder(31) from heater component bracket (9),
c. Inspection
1. Check diode (19) for continuity. Reverse leads on diode (19) and check for continuity. If circuit is open
in both test conditions or closed in both test conditions, replace diode (19).
2. Check resistor (32) for continuity. If continuity does not exist, replace resistor (32).
