ARMY TM 9-2805-257-14 AIR FORCE TO 38G2-103-2 NAVY NAVFAC P-8-612-14E Table 4-2.  Unit Troubleshooting Procedures. MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION 1. ENGINE FAILS TO START. Step 1. Remove air cleaner cup on models 2A016-1, -2, or remove air cleaner element Model 2A016-3, -4. Start engine. If engine starts, service air cleaner (par.  4-20). Step 2. Check ignition switch models 2A016-2, -3, -4 for continuity (para 4-17). Replace ignition switch if defective (para 4-17). Step 3. Inspect spark plugs/High tention cable. a. Clean regap or replace spark plug as necessary (para 4-19). b. Replace a defective high tension cable (4-18). Step 4. Check breaker point gap (para 4-30). Adjust breaker point gap as needed (par.  4-30). NOTE This procedure may be performed with either a digital or analog multimeter. Step 5. Check condenser as follows: NOTE The procedures to test the condenser are the same for both condensers.  Perform the test on one condenser then repeat the procedures for second condenser. a. Turn engine over so that breaker points (para. 4-30, figure 4-21) are in open position. b. Connect positive lead of multimeter to condenser terminal lead. c. Set multimeter to highest resistance setting and zero meter. d. Connect second lead of multimeter to ground while observing meter. If meter shows a deflection, then goes to infinity, then go to next step. If no deflection occurs or does not go to infinity after deflection, replace condenser (para 4-31). If meter doesn’t return to infinity, remove connection between points and condenser and retest.  If deflection occurs, replace points (para.  4-29). 4-4 Change 2
