The AutoTest is one of the best and fastest ways to 
collect comprehensive engine performance data. The 
analyzer will customize the AutoTest based on the 
ignition type selected during Engine Setup. 
The AutoTest sequence steps through the Starting/
Charging History, Ignition Primary, Secondary, and Power Balance tests, and finishes with the Electronic 
Compression test. Each of the tests is described in detail in the Engine Testing section of this manual, 
and can be run individually at any time.
Make sure the engine is warmed up and running, and that all necessary test leads are connected. Enter 
the AutoTest, as described above, and follow the instructions. You will be prompted to perform a variety of 
actions during the test sequence, like cranking the engine during the Starting/Charging History or pressing 
the NEXT key to continue a test after an action is performed. The EngineLink will do the rest, and will 
print a detailed report at the end of the test.

Whenever a test is run, individually or as part of an 
AutoTest, the results are saved for review and printout. 
The resulting printed report will include the most recent 
test readings along with any generated diagnostic 
messages. If no tests have been done, a message will 
advise that no data is available for printing. Disconnecting 
power will erase all saved data.
