What Are the Reasons for a Four-Wheel Vehicle Starter Not Turning?

[McOlive]

There are five reasons why a four-wheel vehicle starter does not turn, which are problems with the battery, electromagnetic switch, relay, internal armature shaft, and anti-theft system. Battery issues: Insufficient battery power or loose connections and dirty terminals causing poor contact. Electromagnetic switch issues: Short circuit in the starter electromagnetic switch coil or poor contact of the contact disc. Relay issues: Burnt relay contacts, open circuit or burnt magnetic coil in the relay. Internal armature shaft issues: Bent internal armature shaft or overly tight bearings, dirty or burnt commutator, excessively worn brushes, overly soft springs preventing contact, short circuit, open circuit, or grounding in the armature or field coils. Anti-theft system issues: Malfunction in the starter anti-theft system.
