Test NS-9C - Repairing No Crank Condition

WARNING: This page is about a different car, the 1995 Dodge Pickup and 1995 Dodge Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: For circuit and connector terminal identification, see CONNECTOR IDENTIFICATION  . For wiring diagrams, see WIRING DIAGRAMS  section at the end of this article.
  1. If engine does not crank, go to next step. If engine cranks and vehicle is equipped with manual transmission, replace starter relay. Perform TEST VER-1. If vehicle is equipped with automatic transmission, go to step 6).
  2. Disconnect jumper wire. Note if starter solenoid clicked when jumper wire was connected. Disconnect starter relay output wire (Brown wire) from starter solenoid. Go to next step.
  3. Using an external ohmmeter, check resistance of Brown wire between starter relay connector and starter solenoid connector. If resistance is more than 5 ohms, repair open in Brown wire. Perform TEST VER-1.
  4. If resistance is less than 5 ohms, reinstall starter relay. Check battery cables for high resistance. If either battery circuit had a voltage drop of more than 0.2 volt, repair battery circuit for high resistance. Perform TEST VER-1. If voltage drop for either battery circuit is less than 0.2 volt, go to next step.
  5. If starter solenoid clicked when jumper wire was connected in step 2), repair starter for a mechanical failure. Perform TEST VER-1. If starter solenoid did not click when jumper wire was connected in step 2), replace starter solenoid. Perform TEST VER-1.
  6. Using scan tool in ohmmeter mode, check resistance of starter relay connector, Park/Neutral Position (PNP) switch sense circuit (Black/White wire). If resistance is less than 5 ohms, replace starter relay. Perform TEST VER-1. If resistance is more than 5 ohms, repair open Black/White wire. Perform TEST VER-1.
