12.10.3.2.1. Complete applicable items on the Cockpit and Before Starting Engines
checklist. CAUTION: Reduce DC load as much as possible to preclude the
possibility of overloading the INS battery.
12.10.3.2.2. Open pilot‘s lower, forward circuit breaker panel.
12.10.3.2.3. Install a #4 jumper wire on the A-1 and A-2 terminals of the battery
relay. (see Figure 12.2)
12.10.3.2.4. Close pilot‘s lower, forward circuit breaker panel.
12.10.3.2.5. Engage Emergency INS Battery Bus Tie Switch above pilot‘s upper
circuit breaker panel.
12.10.3.2.6. DC Voltmeter Switch – Essential DC Bus then Battery Bus, check
voltage. NOTE: If Essential DC Bus is not powered, proceed to paragraph
12.10.3.3. Bypassing the INS Reverse Current Relay (RCR) (Airplanes not modified
by TCTO 1C-130-1723). NOTE: The Battery, Isolated, Essential, and Main DC
Buses will be powered by the INS Battery. Minimize loading on all DC buses.
12.10.3.2.7. DC Power Switch – Battery
12.10.3.2.8. Start GTC/APU
12.10.3.2.8.1. ATM and ATM Generator/APU Generator – ON, check voltage
and frequency
12.10.3.2.9. Start any engine in Normal Ground Idle
12.10.3.2.9.1. Engine GEN switch – ON, check voltage and frequency.
12.10.3.2.10. Review Cockpit and Before Starting Engines checklists.
12.10.3.2.11. Start the remaining engines using the Starting Engines checklist.
12.10.3.2.12. Closely monitor INS battery and aircraft battery bus voltage during
flight. WARNING: The Battery Bus might not be powered if the Isolated DC or
Essential DC Buses are isolated using the flight manual bus isolation procedures. Fire
protection and radio communications might not be available. NOTE: The Essential
DC Bus can be isolated using the flight manual bus isolation procedures but the
Emergency INS Battery Bus Tie Switch above the pilot‘s upper circuit breaker panel
must also be disengaged.
12.10.3.3. Bypassing the INS Reverse Current Relay (RCR) (Airplanes not modified
by TCTO 1C-130-1723). WARNING: When performing maintenance inside any
circuit breaker panel all aircraft power must be removed to prevent injury to personnel or
equipment. WARNING: If the aircraft battery is damaged, disconnect and remove it
from the aircraft. Use caution to avoid acid burns if the battery is leaking.
12.10.3.3.1. Before jumping terminals APP to BATT on the INS RCR you must first
disconnect the INS Battery or arcing may occur.
12.10.3.3.2. Open the pilot‘s upper circuit breaker panel.
12.10.3.3.3. Jump the INS RCR by installing a #10 jumper wire from the APP
terminal to the BATT terminal of the reverse current relay. (See Figure 12.11)
