No Cranking Test

Turn headlights and interior light on. Turn ignition switch to START position. If lights are dim or go out, go to step 5). If lights stay bright, turn on radio and heater.
If radio and heater are inoperative, check bulkhead connector, fusible link and ignition switch connectors. If radio and heater operate, check connections and voltage at starter solenoid terminal "S". See Figure.
If voltage at terminal "S" is greater than 7 volts, repair the starter. If voltage is less than 7 volts, turn the ignition switch to the START position. Check voltage at ignition switch solenoid terminal "S".
If voltage at ignition switch terminal "S" is less than 7 volts, replace ignition switch. If voltage is greater than 7 volts, repair Purple wire from ignition switch to starter solenoid.
If lights are dim or go out, check battery state of charge. If charge is low, charge battery and check for electrical drain. If charge is okay, check cranking voltage at battery posts.
If voltage is less than 9.6 volts, test battery. If battery is okay, repair starter. If voltage is greater than 9.6 volts, check voltage from engine block to battery negative post.
Turn ignition switch to START position (positive lead on engine block). If voltage is greater than .5 volt, clean and tighten ground cable connection and/or replace negative battery cable.
If voltage is less than .5 volt, check cranking voltage at starter terminal "B". If voltage is less than 9 volts, clean and tighten positive battery cable terminals and or replace positive battery cable. If voltage is greater than 9 volts, check fusible link and bulkhead connector. If fusible link and bulkhead connector are okay, repair starter.
