removal and replacement, and shall also contain an electrical starter motor capable of starting the engine under all required conditions and air cooled generator.
3.4.9.11 Air cleaner blower motors. Each air cleaner blower motor shall be capable of providing a flow of air as specified through each blower outlet. The air cleaner blower motor shall be wired so they do not operate unless the engine is running.
3.4.9.12 Engine manifold heater. The vehicle wiring for the manifold heater shall provide a switch-actuated vehicle battery circuit to the engine. Operation of the push button switch on the purge pump handle with starter switch depressed, shall provide vehicular battery voltage to pin "A" of the multiple connector at the engine electrical quick disconnect.
3.4.9.13 Personnel heater. The heater shall be capable of starting with the switch in either high or low position. The blower motor shall operate at reduced speed when the heater is turned on. The burner shall ignite within 4 minutes of heater turn-on. Subsequent to ignition, the heater shall be capable of generating high and low heat and the blower motor shall run at full
speed. Turning the heater "off" shall cause both the burner to extinguish and the blower motor to
shut off within 3.5 minutes.

3.4.9.16 Main gun firing circuits. The main gun firing circuits shall be capable of providing the energy necessary (1.25 ampere for 100 milliseconds) to fire main round. The firing circuit shall also provide the following:
a. The probe shall be grounded at all times except during application of the firing voltage.
b. The firing control circuits shall include the switching feature which prevents
subsequently loaded rounds from detonating until the firing switch has been released after the previous round.
c. Interconnections shall be provided to allow firing circuit activation from the alternate emergency switch on the manual elevation pump handle and provide
emergency mode firing per 3.4.9.18.
