[CassandraFitz]

When the starter does not turn while the engine is hot, the reasons may include battery issues, electromagnetic switch problems, and more. Specific explanations are as follows: Battery Issues: Insufficient battery charge, loose cable connections, or dirty terminals causing poor contact. Electromagnetic Switch Problems: Short circuit in the starter electromagnetic switch coil or poor contact of the contact disc. Relay Problems: Burnt relay contacts, open circuit or burnout of the relay magnetic coil. Internal Armature Shaft Issues: Bent armature shaft inside the starter, overly tight bearings, dirty or burnt commutator, excessively worn brushes, weak springs preventing contact, short circuit, open circuit, or grounding in the armature or field coils. Anti-Theft System Problems: Fault in the starter anti-theft system.
