TM 9-2320-361-20 Table 2-4. Electrical Troubleshooting (Contd). MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION NOTE Testing procedures for left and right turn signal leads 461 and 460 are performed the same using tests 1 through 8. This test covers left side 461 turn signal circuit. Test 2. Test for voltage at front composite lights. Step 1. Disconnect lead 461 at left front composite light. Step 2. Place turn signal lever to LEFT position. Step 3. Set multimeter to a range that will measure 24 volts. Step 4. Touch multimeter negative lead to frame ground. Step 5. Touch multimeter positive lead to contact end of lead 461 (left). Voltage should fluctuate at a rate of 1 or 2 cycles per second. a. If voltage does fluctuate, go to test 3. b. If voltage does not fluctuate, go to test 4. Test 3. Test continuity of filament and socket for turn signal lamp. Check continuity between lead 460/461 attached to front composite light and frame ground. a. If continuity is present, reconnect leads 460/461 and check turn signal operation. If turn signal operates but does not flash, go to tests 6 and 7. b. If continuity is not present, replace turn signal lamp (para. 4-19). 2-111
