ARMY TM 9-2805-257-14 AIR FORCE TO 38G2-103-2 NAVY NAVFAC P-8-612-14E Table 5-1. Direct Support Troubleshooting Procedures (cont). Malfunction Test  or  Inspection Corrective  Action Step 7. Check transformer resistance between white and brown wires. If  resistance  is  more  than  1  ohm  replace  transformer  (para.  5-11). Step 8. Check transformer resistance between white wire and spring on end of high voltage cable. If  resistance  is  not  between  1400  and  2500  ohms,  replace  transformer  (para.  5-11). Step  9.  Check  coil  resistance  between  pins  A  and  B  of  low  voltage  connector  on  engine. If resistance is not between 289 and 329 ohms replace coil (para. 5-20).
