Charging System Test Results; Charging System Decision - Midtronics PowerSensor Micro700 Instruction Manual

6. Testing with accessory loads. After the Diode Ripple Test, the
Micro700 will ask you to:
a. Turn on accessory loads (headlights, blower motor,
defogger, etc.) of at least 40 amps.
b. Test at idle with loads on.
c. Rev engine for another 5 seconds with loads on.
IMPORTANT: When asked to turn on the accessory loads, turn
on the blower to high (heat), turn on the high-beam headlights
and rear defogger. DO NOT use cyclical loads such as air
conditioning or windshield wipers.
6. Analyzing data. The Micro700 will analyze all readings and
provide the results of the Charging System Test.

Charging System Test Results

The Micro700 will display screens that alternate between the
charging decision, a detail of any problem, load voltage
measurements, an evaluation of diode ripple, and a charge code:

Charging System Decision

CHARGING SYSTEM NORMAL
The charging system is operating within a normal voltage range.
CHARGING SYSTEM PROBLEM
A problem was detected in the charging system:
NO CHARGING VOLTAGE
The alternator is not providing charging current to the battery
(pack).
LOW CHARGING VOLTAGE
The alternator is not providing sufficient current for the system's
electrical loads or for charging the battery (pack).
HIGH CHARGING VOLTAGE
The voltage output from the alternator to the battery (pack)
exceeds the normal limits of a functioning regulator and could
overcharge the battery (pack) and decrease its life.
