  • Page 118: Tow Cable Inspection

    5-118 5.7 Tow Cable Inspection If you think the cable or connector has malfunctioned, perform the following three simple cable inspections: Check for cable twisting. • • Check the external jacket. • Perform a point-to-point continuity test of the conductors. Inspect whether any part of the cable was bent beyond the allowable radius.

  • Page 119: Locating An Open Conductor

    5-119 The distance to the short from end #1 is the ratio of R1/(R1+R2) times the total cable length. Recheck from end #2 that is R2/(R1+R2) times the cable length. 5.7.2 Locating an Open Conductor An open conductor in a tow cable is much more difficult to locate than a short. Therefore, a capacitance bridge is recommended to diagnose this problem.
