Checking Ignition Timing
Preparation and Safety
Check ignition timing using timing light.
Whenever you perform a task in the workshop you must use personal
protective clothing and equipment that is appropriate for the task
and which conforms to your local safety regulations and policies.
Among other items, this may include:
•
•
•
•
•
Work clothing - such as coveralls and steel-capped footwear
Eye protection - such as safety glasses and face masks
Ear protection - such as earmuffs and earplugs

This method of checking the timing can only be performed
with the engine running so the belts and fans are moving. As
you point the timing light onto the engine timing marks, be
careful not to reach into the engine compartment far enough
to be injured by any of the moving components.
Remember, the light makes the engine rotating parts look
as if they are standing still, but they are still moving and
dangerous!
