Battery voltage and condition test
Separate state of charge, battery condition, and connection problems before blaming the starter or alternator.
Test-first procedureCharging-system test
Check whether the vehicle is replenishing electrical energy under its intended operating strategy instead of applying one universal voltage rule.
Test-first procedureVoltage-drop test
Find resistance in a loaded power or ground path without assuming that continuity or an unloaded voltage proves the circuit is healthy.
Test-first procedureStarter-circuit test
Separate start-request, interlock, cable, ground, solenoid, and starter-motor evidence before bypassing the circuit or replacing the starter.
Test-first procedureCrank-but-no-start evidence test
Separate missing ignition, fuel delivery, control, synchronization, and mechanical evidence after the engine is confirmed to crank.
Test-first procedureMisfire pattern and contribution test
Use warning behavior, scan context, cylinder pattern, and controlled contribution evidence to separate ignition, fuel, air, and mechanical branches.
