Starters That Remain Engaged After Engine Is Running
Usage:
All Engines With Electric Starters
Several things can cause starters to remain engaged after the engine is running. Indications that this has occured include:
-
- 1. Worn bearings in the starter drive assembly.
- 2. Starter drive teeth are badly worn on the reverse side.
- 3. Armature commutator has exploded.
- 4. Discoloration of the starter end cap.
- 5. Solenoid coils are open, or shorted windings.
- 1. Worn bearings in the starter drive assembly.
If the above symptoms are observed, the starter is not usually at fault. Check for one or more of the following problems.
-
- 1. Stuck or sticking dash mounted start switch (most probable).
- 2. Stuck or sticking solenoid contacts (check battery).
- 3. Stuck or sticking starter relay (if applicable).
- 4. Failure of the wiring harness, battery positive to start circuit, anywhere between the start switch and the starter solenoid.
- 5. Loose and/or incorrectly positioned wiring on the solenoid. This can cause the solenoid to engage the starter.
- 1. Stuck or sticking dash mounted start switch (most probable).
