Replacing a starter motor seems straightforward, but these common mistakes can lead to failure:
1. Incorrect Diagnosis
- Many assume a non-starting car needs a new starter, but a weak battery or faulty alternator may be the real cause. Always test components before replacing the starter.
2. Forgetting to Disconnect the Battery
- Working on the starter without disconnecting the battery can cause electrical short circuits.
3. Improper Installation
- Bolts must be tightened correctly, and wiring should be securely connected. Loose connections can cause starting issues.
4. Using the Wrong Starter Motor
- Different models require specific starter designs. Always match the part number before purchase.
5. Ignoring Warning Signs After Installation
- A slow crank or clicking sound after replacement may indicate an issue with wiring or battery power.
Avoiding these mistakes ensures a smooth and successful starter replacement.
