Test C: Starter Cranks Slowly

WARNING: This page is about a different car, the 2004 Ford Focus and 2003 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ensure battery is fully charged. Engage parking brake and place transmission selector in Neutral. Connect Starter, Alternator, Battery, and Regulator (SABRE) tester, or equivalent. Follow tester manufacturer's instructions. If starter tests okay, go to next step. If starter does not test okay, replace starter. See STARTER MOTOR  under REMOVAL & INSTALLATION.
  2. Measure the voltage between starter motor connector terminal No. 1 (component side) and the positive battery post with the ignition switch in the ON/RUN position. If voltmeter displays less than .5 volt, go to next step. If voltmeter displays greater than .5 volt, clean and tighten all positive battery terminal connections. If fault is still present, replace positive battery cable. Retest for normal operation.
  3. Measure voltage between starter housing and negative battery cable, with ignition switch in ON/RUN position. If voltmeter displays less than .5 volt, repair charging system. See appropriate CHARGING SYSTEM article in ELECTRICAL. If voltmeter displays greater than .5 volt, clean and tighten all negative battery cable connections, starter motor mounting and body to engine grounds. If concern still exists, replace negative battery cable. Restore electrical connections and retest system operation.
