Troubleshooting Recommendations:

  1. Perform wiring checks for shorted to ground between EVSHC and the fairing as follow:
    NOTE: Nominal resistance between heater terminals is 23.42 ohms ±2.8 ohms at 20 °C (68 °F).

    From To Result
    A315P1-FF HR30J1-L
    A315P1-EE HR30J1-C
    A315P1-DD HR30J1-G
    A315P1-LL HR30J1-M (115 VAC RTN)

    1. If wiring checks are not good, repair defective wiring as required and do close out.
    2. If wiring checks are good, continue with next step.

  2. Perform wiring checks for short circuit of EVSHC and fairing as follow:
    NOTE: repair wiring when it is shorted.

    From To Result

    HR30P1-C HR30P1-M/Backshell
    HR30P1-G HR30P1-M/Backshell

    1. If wiring checks are not good, repair defective wiring as required and do close out.
    2. If wiring checks are good, continue with next step.

  3. Replace fairing.

    1. If system checks are good, do close out.
    2. If fault remains, continue with next step.

  4. Replace EVSHC.
  5. Do close out.
