TM 10-3930-671-24 Before Disassembly Tests For additional information, please refer to: Section 2.1, Service Specifications Section 4.3, Engine Tune-Up Section 6. 1, Electrical System Wiring Section 6. 11, Starting System Troubleshooting Section 6.12, Starter Motor Troubleshooting Remove  all  jewelry  (watch,  rings,  bracelets,  etc.)  before working  on  electrical  systems.    Severe  burns  can  result from contact with electrical circuits. Always follow the manufacturer’s instructions for the test instrument   being   used   when   making   connections   and tests on electrical circuits. 1. Starting Circuit Troubleshooting Refer to Section 6.  11, Starting System Troubleshooting, and  Section  6.    12,  Starter  Motor  Troubleshooting,  for additional starter problem troubleshooting procedures. Many of the problems related to the starter can be found without   removing   the   starter.      If   a   starter   problem   is suspected,  it  is  suggested  to  check  the  following  items before removing the starter from the engine. a.   Check battery: 1) electrolyte level and adequate charging. 2) terminals for tightness and corrosion. 3) for cracked case or damaged cells. b. Check starter terminals for tightness and corrosion. c. Starting circuit wiring for grounding or opens. d. Starter for poor grounding. e. Starter switch relay for improper function. f. Ignition key switch for improper function. g. Starter solenoid switch for improper function. If no abnormality has been found with the circuit, remove the starter from the engine and test it. 2. No-Load Test Refer to Section 6.  12, Starter Motor Troubleshooting. The starter may be considered normal if it runs smoothly with    the    current    and    speed    showing    the    specified standard  values   when   the   specified   battery   voltage   is applied. If   any   abnormality   is   found   during   the   no-load   test, disassemble and inspect the starter. Starter Removal NOTE To  perform  this  procedure,  it  is  recommended  that  you first: • Remove left-and right-side doors. • Open top hood. • Remove    cooling    system    compensation tank. • Tag and mark all wires prior to removal. • Remove nut, screw, and strap, and move hose from bracket. • Unhook throttle spring. • Remove  nut,  washer,  and  throttle  linkage from fuel injector pump.
