SYSTEM TEST RESULT
"CRANKING VOLTS NORMAL"
The system cranking voltage is in a good range.
"CRANKING VOLTS LOW"
The cranking voltage is below normal limits,
troubleshoot the starter with manufacturers recommended procedure.
"CRANKING VOLTS NO DETECTED"
The cranking voltage is not detected.
SYSTEM TEST RESULT
"ALT. IDLE VOLTS NORMAL"
The system is showing normal output from the alternator. No problem is detected.
"ALT. IDLE VOLTS LOW"
The alternator is not providing sufficient current to the battery.
Check the belts to ensure the alternator is rotating with engine running, if the belts are slipping or
broken, replace the belts and retest.
Check the connections from the alternator to the battery, if the connection is loose or heavily
corroded, clean or replace the cable and retest, if the belts and connections are in good
condition, replace the alternator.
"ALT. IDLE VOLTS HIGH"
The voltage output from the alternator to the battery exceeds the normal limits of a functioning
regulator. Check to ensure there is no loose connection and the ground connection is normal, if
there is no connection issue, replace the regulator. Since most alternators have the regulator
built-in, this will require you to replace the alternator.
The normal high limit of a typical automotive regulator is 14.7 volts +/- 0.05.
Check manufacturer specifications for the correct limit, as it will vary by vehicle type and
manufacturer.
SYSTEM TEST RESULT
"ALT. LOAD VOLTS NORMAL"
The system is showing normal output from the alternator. No problem detected.
"ALT. LOAD VOLTS LOW"
The alternator is not providing sufficient current for the systems electrical loads and the charging
current for the battery.
Check the belts to ensure the alternator is rotating with the engine running, if the belts are
slipping or broken, replace the belts and retest.
Check the connections from the alternator to the battery, if the connection is loose or heavily
corroded, clean or replace the cable and retest. When the belts and connections are in good
working condition, replace the alternator.
"ALT. LOAD VOLTS HIGH"
The voltage output from the alternator to the battery exceeds the normal limits of a functioning1
regulator.
Check to ensure there are no loose connections and that the ground connection is normal, if
there are no connection issues, replace the regulator. Since most alternators have the regulator
built-in, this will require you to replace the alternator
