Check oil cooler and oil cooler lines for dirt and/or restrictions (Appendix F, Transaxle Maintenance, Section 7.1). If oil cooler is dirty or oil cooler lines have restrictions, drain and flush oil cooler (Appendix F, Transaxle Maintenance, Section 7.1) or replace faulty lines (Para 3-30). If oil cooler is not dirty and oil cooler lines have no restrictions, go to step 3. Step 3. Check converter inlet pressure (charging pump pressure) at regulator valve (Appendix F, Transmission Pressure Checks, Section 7.3). If converter inlet pressure is not 150-195 psi (1034-1172 kPa) at 1800 rpm, drain and flush hydraulic tank and screen (Appendix F, Transaxle Maintenance, Section 7.1). If converter inlet pressure is between 150-195 psi (1034-1172 kPa) at 1800 rpm, charging pump faulty.  Notify DS/GS maintenance. ELECTRICAL SYSTEM 34. ENGINE WILL NOT CRANK. Step 1. Check continuity across ignition fuse (TB ORD 650). If ignition fuse has no continuity, replace ignition fuse (Para 3-22). If ignition fuse has continuity, go to step 2. Step 2. Check battery connections. If battery connections are loose and/or corroded, clean, tighten, or replace connec- tions (Para 3-27). If battery connections are tight and clean, go to step 3. Step 3. Test batteries (Appendix F, Starting System Troubleshooting, Section 6.11). If test result indicates batteries are faulty, replace batteries (Para 3-25). If test result indicates batteries are OK, go to step 4. 2-22
