NOTE: Stop switches include the ignition switch and the engine cut-out switch.
It is important to take note that voltage measurements must be taken while starting the vehicle using the
manual starter.
Voltages obtained upon starting are proportional to the force applied onto the manual starter. A low voltage
is therefore normal under a low cranking force.
Perform testing in the prescribed order and replace any parts not performing according to specifications.
It is important to resume all test when replacing a component.
It not specified, the probe connecting sequence is not important.
