Starter Motor - Load Test
WARNING: This page is about a different car, the 2007 Lincoln Mark LT and 2007 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
When servicing the starter motor or carrying out other underhood work in the vicinity of the starter motor, be aware that the heavy gauge battery input lead at the starter solenoid is "electrically hot" at all times. Failure to follow this instruction may result in personal injury.
CAUTION:
A protective cap or boot is provided over the battery input terminal on all car lines and must be installed after repair. Be sure to disconnect the battery ground cable before repairing the starter motor.
- Before carrying out this test inspection, check the battery to determine the state of charge. Carry out a load test of the battery. Refer to BATTERY, MOUNTING AND CABLES article for the test procedure.
- Disconnect the ignition coil connector from the ignition coil.
- Connect the SABRE Tester to the vehicle using the amperage lead clipped around the positive battery cable.
- Measure the amperage of the starter motor while activating the starting system.
- A correctly operating starter motor will draw from 130 to 190 amps of current at room temperature.
