Subsection 07 (TESTING PROCEDURE)

NOTE: Stop switches include the ignition switch, the tether cord switch and the emergency 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 tests when replacing a component.
If not specified, the probe connecting sequence is not important.
