Check continuity of socket ground.If there is no continuity, repair or replace turn signal/taillight socket assembly (para 4-79).If there is continuity, go to step 4.NOTEThe terminals are G for the right hand turn signal.Step 4. Check continuity across intervehicular cable (at terminals Y).If there is no continuity, replace intervehicular cable.If there is continuity, go to step 5.NOTEThe wire for the right hand turn signal is green.Step 5. Check voltage on 12-volt socket/cable (terminal Y) at terminal strip (left hand turn signal terminal) injunction box.If 12 +3 vdc are not measured, replace 12-volt socket/cable (para 4-91).If 12 ±3 vdc are measured, go to step 9.NOTEThe terminal is J and the wire green for right hand turn signal.Step 6. Check continuity across 24-volt cable (connector, terminal B and yellow wire in resistor box).If there is no continuity, replace 24-volt cable (para 4-87).If there is continuity, go to step 7.Step 7. Check resistance across turn signal resistor.If resistance is not 5 ±2 ohms, replace resistor box (para 4-74).If resistance is 5 +2 ohms, go to step 8.4-27
