TM 1-1510-223-10 8-18           Change 3 7.   TGT and N₁ — Monitor (TGT 1000° C Maxi- mum). 8.   Oil pressure — Check (60 PSI minimum). 9.   ENG START switch — OFF after TGT peaks. 10.   CONDITION  lever  —  HIGH  IDLE.  Monitor TGT as CONDITION lever is advanced. 11.   Generator  switch  (operating  engine)  —  RE- SET, then ON. 8-15.   *SECOND ENGINE START (BATTERY START). 1.   Generator load — Verify less than 50%. 2.   Propeller area — Clear. 3.   ENG START switch — START-IGNITION. IGN ON annunciator should illuminate and FUEL PRESS annunciator should extinguish. 4.   CONDITION lever (after N₁ RPM passes 13% minimum) — LOW IDLE. 5.   TGT and N₁ — Monitor (TGT 1000° C maxi- mum). 6.   Oil pressure — Check (60 PSI minimum). 7.   ENG START switch — OFF after TGT peaks. 8.   CONDITION  levers  —  HIGH  IDLE.  Monitor TGT as CONDITION lever is advanced. 9.   Deleted. 10.   PROP levers — HIGH RPM. 11.   Deleted. 12.   INVERTER switches — ON, check INVERT- ER annunciators off. 13.   Current limiters — Check as follows: a.   BATTERY     CHARGE     annunciator     — Check on. BATTERY CHARGE annuncia- tor should extinguish within 5 minutes fol- lowing   a   normal   engine   start   on   the battery. b.   #1 and #2 INV annunciators — Check ex- tinguished.  This  procedure  checks  both the 400 and 500 ampere current limiters that tie aircraft bus systems together. c.   Check   for   generator   voltage   on   BATT VOLT/AMP meter. 14.   GENERATOR  switch  —  Second  switch  RE- SET, then ON. NOTE To reset beacon light, turn off for approximately 5 seconds, then DAY or NIGHT. When voltage drops below approximately 20 VOLTS, the bea- con light may become inoperative. 15.   BEACON lights switch — Reset, then ON. 8-16.   ABORT START PROCEDURE. 1.   CONDITION lever — FUEL CUTOFF. 2.   ENG START switch — STARTER ONLY. 3.   TGT — Monitor for drop in temperature. 4.   ENG START switch — OFF. 8-17.   ENGINE CLEARING PROCEDURE. 1.   CONDITION lever — FUEL CUTOFF. 2.   ENG START switch — OFF (15 minutes mini- mum). 3.   ENG START switch — STARTER ONLY. 4.   ENG START switch — OFF. 8-18.   *FIRST ENGINE START (GPU START). When making a ground power unit (GPU) start, the left engine should be started first due to the GPU receptacle being adjacent to the right engine. If only one engine is started utilizing the GPU, revert to the battery start proce- dure for the second engine start. * 1.  INS mode selector switch — OFF or NAV as appropriate. After placing mode switch to NAV (state 5 or less): a.   FPLN — Depress. b.   NAV SETUP (R5) — Depress. c.   INS SETUP (R5) — Depress. d.   AUTOMIXING (R3) — Select TACAN, DL, or GPS. e.   ROLL LIMIT (R2) — Select ON or OFF, as desired. f.   LEG  CHANGE  (L3)  —  Select  MAN  or AUTO, as desired
