Inspect wiring harness terminals (2 and 4) wire, spade terminal (13)
wire, and turn signal switch (12) terminals (3 and 5) wire for cracked or
broken insulation or broken wire strands at connection to terminals. Re-
pair cracked or broken insulation by applying insulation tape to area. If
broken wire strands are seen, cut wire as close to terminal as possible.
Strip 1/4 inch insulation from end of wire taking care not to cut through
wire then crimp new terminal securely onto wire.
Inspect turn signal switch (12) for cracks, breaks, and bent or deformed
lever; replace if any of these conditions are seen. With lever in center
position, connect multimeter across terminal (3) and spade terminal (6)
and check that multimeter indicates open circuit (infinity). Move lever
up and check that multimeter indicates continuity. Return lever to center
p o s i t i o n .
Connect multimeter across terminal (5) and spade terminal (6)
and check that multimeter indicates open circuit (infinity). Move lever
down and check that multimeter indicates continuity. Replace switch if
proper indications are not obtained on multimeter.
Inspect flasher (18) for cracks, dents, breaks, and loose or corroded
terminals; replace if any of these conditions are observed. Connect 24
volts between terminal 1 and metal case of flasher. Connect a 24 volt
test light between terminal 2 and metal case of flasher. Check that test
light flashes on and off. If test light does not flash on and off, re -
p l a c e f l a s h e r.
Inspect remaining parts for cracks, breaks, deformation, distortion, and
stripped threads; replace as necessary.
