How to test:
Connect the red test clamp to the battery positive (anode) and black to battery
negative (cathode), the SPTG1 then will power on automatically. After the
display illuminates press OK key to continue.
Note: Battery voltages below 7.0VDC will not test properly (Charge battery rst
if below 7VDC then retest)
The display menu will allow for the following choices, you can press UP/
DOWN key to choose the desired option:
1) battery test
2) starting system test
3) charging system test
4) battery test result
5) print test result
6) select language
Battery Test
• Select the battery test and press OK key to continue:
• Input testing standard: the standard which you can see on the front
of the battery, such as CCA, BCI, DIN, CA, etc. CCA or CA are the
most common. CA is the standard for Stinger AGM batteries and
car audio applications.
• Input rated capacity: you can see the starting current standards of
the battery, such as CCA/800A. This is usually listed on the battery
label. Note: This determines the threshold for Pass/Fail based on
battery specications. Inaccurate setting of this target can cause
incorrect Pass/Fail results.
• Then press OK key to start testing.
Note
If battery is in discharged state (such as a vehicle in storage so battery has not
been charged in a long time; excessive drain from headlights left on or doors
left open, resulting in a serious loss of battery power and vehicle and cannot
be started, etc.), the actual testing process may result with “Please replace
the battery.” For such batteries, please consult the battery manufacturer’s
charging requirements and charge the battery then retest.
NOTE: If no increase in RPM is detected, it could be fault of alternator, reg-
ulator or connection to battery failed. SPTG1 will try 3 times to detect RPM,
if no RPM detected, it will skip the increase RPM detect and the test result
will display “No Volt Output”. Check the connection between alternator and
battery, then retest.
Charging Test Result:
1. Charging Volt: Normal. The alternator output normal, no problem detected.
2. Charging Volt: Low. Check drive belt of the alternator for wear and/or
slippage. Check that the connection between alternator and battery is good.
If both the drive belt and the connection are in good condition, follow the
manufacturer’s suggestion to eliminate alternator as faulty.
3. Charging Volt: High. Since most alternators use an internal regulator, the
alternator assembly must be replaced. (Some pre-1990 vehicles use an
external regulator; if equipped, just replace the regulator.) The normal high
volt of the voltage regulator is maximum 14.7±0.5V. (Some newer vehicles will
exceed 15V+). If charging volt is too high, it could possibly overcharge the
battery. Causing premature failure of battery from overcharging. Systems that
are designed charge at a high voltage can compensate for this and it is not an
issue. Check vehicle specications if output is over expected range and verify
if this is the desired function.
4. No Volt Output: No voltage output is detected. Check the alternator
connection cable, the drive belt of alternator and engine to see if they’re in
good condition and working properly.
5. Diode Test: While testing charging current ripple, the SPTG1 will determine
whether the diode is functioning properly. When ripple voltage is too high, it is
possible that at least one diode is damaged. Check and replace the diode if
possible or repair/replace alternator.
