Starter Performance Test: Test
How to use this Service Information .
NOTE:
- Before this test, clamp the starter firmly in a vise.
- Make the connections for this test using the thickest (gauge) wire possible (preferably the same gauge as used on the vehicle).
- To avoid damaging the starter, never leave the 12 volt battery connected for more than 5 seconds.
- Starter Performance (Suction) - Test
■ Preconditions
■ Procedure/Specifications
- Connect the 12 volt battery as shown, and check for continuity between the B terminal and the starter body.
Normal Conditions
- B terminal and starter body has continuity
- Starter pinion moves out
■ Result
- If it is abnormal, replace the starter.
- Starter Performance (Retract) - Test
■ Preconditions
Figure 1
■ Procedure/Specifications
1. Connect the 12 volt battery as shown, and check for continuity between the B terminal and the starter body. (Figure 1)
Figure 2
2. Disconnect the 12 volt battery from the starter body, and check the starter performance. (Figure 2)
Normal Conditions
- B terminal and starter body has no continuity
- Starter pinion retracts immediately
■ Result
- If it is abnormal, replace the starter.
- Starter Performance (No Load) - Test
■ Preconditions
■ Procedure/Specifications
- Connect the starter to the 12 volt battery as shown, and confirm that the motor runs.
If the electric current meets the specification, when the 12 volt battery voltage is at 11.5 V.
Normal Conditions
Specifications Electric Current 80 A or less ■ Result
- If the measurement is not within specifications, replace the starter.
- Connect the starter to the 12 volt battery as shown, and confirm that the motor runs.
