Charge Code (For Micro700Bmp Only); Charging System Test - Midtronics PowerSensor Micro700 Instruction Manual

Charge Code—Starting System (for Micro700BMP only)
The display will alternate between screens showing the test results
and a 9-character charge code.

CHARGING SYSTEM TEST

You can perform the Starting System Test by itself or within a Full
System Test. When the engine is running, the Micro700 will help you
perform the procedure for a charging system analysis.
IMPORTANT: If you test 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 retest the vehicle.
(If the analyzer asks if the vehicle has glow plugs, see "Glow Plug
Detection" in the "Additional Features" section.)
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.
1. Press ENTER at the prompt to begin the Charging System Test..
2. The Micro700 displays real-time alternator output voltage.
Press ENTER to continue.
3. Testing at rev. The Micro700 will prompt you to rev the engine
for 5 seconds. When it has detected the rev, it will collect data.
If the analyzer does not detect a rev, it will prompt you to press
ENTER to continue.
IMPORTANT: In vehicles that idle at a high rpm after starting, the
analyzer may detect the rev without prompting you. The test
results will not be affected.
4. Testing at idle. The Micro700 will analyze the charging system
output at idle for comparison to other readings.
5. Diode ripple test. The Micro700 will look for the amount of ripple
from the charging system to the battery. Excessive ripple usually
means one or more diodes have failed in the alternator or there
is stator damage.
