  § 80.862   Proof of capacity.

   (a) When directed by the Commission or its authorized representative,
   the station licensee must prove that the requirements of § 80.861 are
   met.

   (b) Proof of the ability of a battery used as a main or reserve source
   to operate continuously for 6 hours can be established by a discharge
   test over a prescribed period of time, when supplying power at the
   voltage required for normal and operation to an electrical load as
   prescribed by paragraph (d) of this section.

   (c) When the reserve power supply is an engine-driven generator, proof
   of the adequacy of the engine fuel supply to operate the unit
   contiuously for 6 hours can be established by measuring the fuel
   consumption for 1 hour when supplying power, at the voltage required
   for normal operation, to an electrical load as prescribed by paragraph
   (d) of this section.

   (d) In determining the electrical load to be supplied, the following
   formula must be used:

   (1) One-half of the current of the required transmitter at its rated
   power output.

   (2) One fourth of the current of the automatic radiotelephone alarm
   signal generator; plus

   (3) Current of receiver; plus

   (4) Current of emergency light(s); plus

   (5) Current of the bridge-to-bridge transceiver when connected.

   (e) At the conclusion of the test specified in paragraphs (b) and (c)
   of this section, no part of the main or reserve power supply must have
   an excessive temperature rise, nor must the specific gravity or voltage
   of any battery be below 90 percent discharge point of the fully charged
   value.
