12.10.3.10.1. Remove all electrical power.
12.10.3.10.2. Open pilot‘s side circuit breaker panel.
12.10.3.10.3. Check GTC starter current limiter; (see Figure 12.2) if bad or suspect;
replace as follows:
12.10.3.10.3.1. Disconnect battery.
12.10.3.10.3.2. Remove and replace current limiter with spare.
12.10.3.10.3.3. If no spares are available, open copilot‘s upper circuit breaker
panel cover, remove cargo winch current limiter and use as a replacement.
12.10.3.10.4. If current limiter is good check GTC starter for broken wires and repair
as necessary (see Figure 12.3).
12.10.3.10.5. Connect battery and attempt to start. If no rotation, tap starter relay and
attempt another start.
12.10.3.10.6. If GTC still will not rotate, place the GTC control switch to START
momentarily to energize the relay, then release the switch to RUN. Place a #4 jumper
wire between post A1 and A2 of the GTC relay (see Figure 12.2) until the start light
goes out, then remove the jumper wire.
12.10.3.11. *GTC Fuel Vapor Lock
12.10.3.11.1. Use petcock drain on bottom of aircraft below GTC to drain fuel while
motoring GTC, then attempt start (see Figure 12.4).
12.10.3.11.2. If no fuel is present at petcock drain, check GTC fuel shutoff valve
opening by momentarily positioning GTC control switch to ―START‖ then ―OFF‖.
12.10.3.11.3. If fuel shutoff valve fails to operate, remove cannon plug and open the
valve manually.
12.10.3.11.4. Remove fuel line at GTC burner can and motor GTC until a steady
stream of fuel is noted. This procedure may require several attempts to attain desired
results.
12.10.3.11.5. Reconnect the line and attempt another start.
12.10.3.12. * GTC Rotates-No Light OFF
12.10.3.12.1. Check oil quantity.
12.10.3.12.2. Attempt to start while depressing the oil primer button. NOTE: A
failed speed switch may prevent starter engagement up to 35 percent and/or the bleed
air valve to open at 95 percent. If this occurs proceed as follows:
12.10.3.12.3. Remove Speed Switch cannon plug, place No. 16 jumper wires with
pins from kit, from pin A to pin E (95 percent) and pin D to pin B (110 percent), and
pin D to pin C (35 percent).
12.10.3.12.4. Start GTC. At approximately 35 percent pull wire from D to C out.
NOTE: After starting an engine, remove power from GTC and remove jumper wires.
12.10.3.13. Starting GTC with Failed Oil Pressure Switch
