Starter System Test Results; Testing The Charging System - Midtronics Celltron START+ Instruction Manual

• Air—The vehicle has an air starter. This selection will bypass the
starting (electrical) system test. You will be prompted to start the
engine, and then press ENTER to continue. The analyzer will
proceed to the Charging System Test.
• Conventional—The vehicle has a conventional electrical starter.
You will be prompted to start the engine. During the engine crank
or starting cycle, the analyzer analyzes the starter for proper
operation. At the conclusion of the test, the Analyzer will display
one of the following results:

STARTER SYSTEM TEST RESULTS

The analyzer will display the cranking voltage of the starter and one
of the following decisions:
• CRANKING VOLTAGE NORMAL—The starting system is
showing normal starter draw.
• CRANKING VOLTAGE LOW—The cranking voltage is below
typical limits; troubleshoot the starter electrical system using the
manufacturer's recommended procedure. If you are performing a
Full System Test, press ENTER to proceed to the Charging
System Test.

TESTING THE CHARGING SYSTEM

A Charging System Test can be performed by itself or within a Full
System Test. With the vehicle running, you will be prompted to
perform steps necessary for the analyzer to perform a charging
system analysis.
IMPORTANT: When testing older model diesel engines in cold
weather, pre-heating and post-heating of the glow plugs may
skew the test results. Warm up the engine for 5 minutes and
then retest the vehicle.
Check the belts to ensure that the alternator is rotating when
the engine is running. If the belts are slipping or broken, replace
the belts and retest. Check all connections to and from the
alternator, especially the connection to the battery. If the
connection is loose or heavily corroded, clean or replace the
cable and retest.
