Test 6. Test for voltage at rear
composite light.
1. Disconnect lead 22-461 at left
rear composite light
2. Turn main light switch to
SERVICE DRIVE position.
3. Place turn signal switch in left
position.
4. Set multimeter to a voltage
range that will measure
24 VDC.
5. Touch multimeter negative
lead to frame ground.
6. Touch multimeter positive lead
to contact end of lead 22-461.
Voltage should fluctuate at a
rate of 1 or 2 cycles per second.
Test 7. Test continuity of filament and
socket for turn signal lamp.
Check continuity between lead
22-460-461 attached to rear composite
light and frame ground.
Test 8. Test continuity of lead 22-461
from turn signal switch to rear
harness connector.
1. Set multimeter to RX 1 scale.
2. Disconnect cable connector at
turn signal switch.
3. Disconnect lead 22-461 from
rear composite light.
4. Touch multimeter negative
lead to contact end of lead
22-461.
5. Touch multimeter positive lead
to contact end of lead 22-461 at
turn signal cable connector
(pin C).
1. If voltage does fluctuate, go to
test 7.
2. If voltage does not fluctuate, go to
test 8.
1. If continuity is present, reconnect
lead 22-460-461 and check turn
signal operation.
2. If continuity is not present, replace
turn signal lamp (WP 0102 00).
If continuity is not present, repair or
replace lead 22-461 (WP 0090 00).
