2000 Saturn LW1 AutomaticSECTION Cranking Test
CAUTION:
Never operate starter for periods of more than 15 seconds. Excessive cranking can cause starter to overheat. Allow starter to cool for at least 20 seconds between operations.
- Using a starting system load tester, connect positive and negative leads to battery. Connect inductive ammeter pick-up to positive battery cable. Ensure ammeter pick-up is pointing toward starter. Easiest place to connect inductive pick-up to positive battery cable is in front of brake master cylinder.
- Ensure all lights and accessories are off. Place transaxle in Park (A/T) or Neutral (M/T) position or depress clutch (M/T). Set parking brake. Crank engine and observe reading. See STARTER SPECIFICATIONS . If voltage is more than 9.5 volts and cranking amperage draw is more than specified, check for excessive resistance in suspect starting system circuit or component. If voltage is 12.5 volts or more and cranking amperage draw is less than specified, check for low resistance in suspect starting system circuit or component.
