Remove all jewelry such as rings, dog tags,
bracelets, etc. If jewelry or tools contact
positive electrical circuits, a direct short
may result. Damage to equipment, injury or
death to personnel may occur.
Adhesives, solvents, and sealing compounds
can burn easily, can give off harmful vapors,
and are harmful to skin and clothing. To
avoid injury or death, keep away from open
fire and use in a well ventilated area. If
adhesive, solvent, or sealing compound gets
on skin or clothing, wash immediately with
soap and water.
(1) Set multimeter select switch to ohms.
(2) Is there continuity between transfer
case lockup solenoid connector
M49, terminal 2 and a known good
ground?
(a) If there is no continuity, repair
wire 1435 (see schematic
Fig 2-42) or notify DS
Maintenance.
(b) If there is continuity, wire 1435
is OK.
CONTINUITY TEST
(1) Turn transfer case solenoid valve
manual override screw counter–
clockwise and listen for air passing
through valve.
(a) If air passes through valve,
