Causes of Premature Starter Failure

• Water Intrusion is Cause #1
  • From Engine (Leaking exhaust manifolds, gaskets, etc)
• Oil Leak
• Overheating
  • Slow Cranking
    • Low Voltage at the starter B+ terminal
      • Excessive current flow kills the starter. Low  voltage results in lower starter rpm which increases current
      • 📝 Starter and low voltage
  • Prolonged cranking
  • ‘S’ terminal is hanged on B+
    • Ignition Switch
• High engine vibration
