TM 5-3805-262-2012-1. SIGNALING DEVICES MAINTENANCE (CONT) c. Turn Signal Switch and Flasher (cont).INSPECTION, REPAIR, AND TESTING(1)(2)(3)( 4)Inspect wiring harness terminals (2 and 4) wire, spade terminal (13)wire, and turn signal switch (12) terminals (3 and 5) wire for cracked orbroken insulation or broken wire strands at connection to terminals. Re-pair cracked or broken insulation by applying insulation tape to area. Ifbroken 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 throughwire then crimp new terminal securely onto wire.Inspect turn signal switch (12) for cracks, breaks, and bent or deformedlever; replace if any of these conditions are seen. With lever in centerposition, connect multimeter across terminal (3) and spade terminal (6)and check that multimeter indicates open circuit (infinity). Move leverup and check that multimeter indicates continuity. Return lever to centerp 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 leverdown and check that multimeter indicates continuity. Replace switch ifproper indications are not obtained on multimeter.Inspect flasher (18) for cracks, dents, breaks, and loose or corrodedterminals; replace if any of these conditions are observed. Connect 24volts between terminal 1 and metal case of flasher. Connect a 24 volttest light between terminal 2 and metal case of flasher. Check that testlight 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, andstripped threads; replace as necessary.12-12
