2. If the unit detects that the alternator is good, the LCD screen will display the following:
The pump engine icon will light solid, and the bars on the battery icon will change from empty to solid (bottom to top)
repeatedly.
3. If the unit detects that the alternator is out of typical voltage range, the LCD screen will display the following:
The half-full battery icon will light solid and the triangular alarm icon will flash.
4. Press the alternator check button again to stop the test.
Notes:
The battery voltage check button is disabled in alternator check mode.
The unit may detect that the alternator is out of typical voltage range because someone has added a number of accessory loads on the charging system,
thereby increasing current demand from the alternator. MAKE SURE THAT THE ALTERNATOR IS RATED TO SUPPORT THE APPLICATION.
This check may not be accurate for every make, manufacturer and model of vehicle. Check only 12 volt systems.
When disconnecting the charger, disconnect AC cord, remove clamp from vehicle chassis, and then remove clamp from battery terminal.
Checking the Battery Voltage
1. Set up the battery charger and connect to the battery following steps 1 through 2 in the “Charging the Battery” section.
2. Press the battery voltage check button. The LCD screen will display the following:
The digital display shows the current voltage of the connected battery.
To check the battery voltage while in charging mode, press the battery voltage check button and the LCD screen will display the
following:
When disconnecting charger, disconnect AC cord, remove clamp from vehicle chassis, and then remove clamp from battery
terminal.
reconditioning the Battery
Periodic reconditioning is recommended to maintain a battery’s optimum performance. Battery recondition sends a series of
electrical pulses to break up the crystalline form of lead sulfate and turn these chemicals into useful battery electrolytes. The
process will stop automatically after 24 hours. To stop the process sooner, press the battery recondition button a second time. More
than 24 hours may be needed to restore performance on some batteries. If so, repeat the process.
1. Set up the battery charger and connect to the battery following steps 1 through 2 in the “Charging the Battery” section.
2. Press the battery recondition button. The LCD screen will display the following:
The bars on the battery icon will change from solid to empty (top to bottom) repeatedly and the icons pointing to the “+” and
“–” flash.
IMPORTANT:
If 5 cycles of reconditioning does not improve battery performance, discontinue and recycle the battery.
When disconnecting charger, disconnect AC cord, remove clamp from vehicle chassis, and then remove clamp from battery
terminal.
using the engine start timer (BC1509)
1. Set up the battery charger and connect to the battery following steps 1 through 2 in the “Charging the Battery” section.
2. Press the engine start timer button. The LCD screen will display the following*:
IMPORTANT:
If the charger detects a problem with the battery, the LCD screen will display the fault indication icon (the clamp
icon will light and the empty battery icon will flash):
Disconnect the charger. Have the battery checked by a qualified technician.
4.
BC1509:
When the battery is completely charged, the unit automatically goes into float charge mode and the LCD screen
displays the following:
The digital display shows “FLO” to indicate that the unit is in float charge mode. The battery fully charged icon will display on
the LCD screen and the arrows pointing to the “+” and “-” will flash. In this mode, the unit monitors the battery voltage and
charges as necessary to assure the battery maintains full capacity. The unit remains in float charge mode as long as the charger
is connected to the battery and plugged into a functioning AC outlet.
BC2509 and BC4009:
When the charging is complete, the arrow and clamp icons and digital display stop displaying. The
battery fully charged icon will display on the LCD screen:
When disconnecting charger, disconnect AC cord, remove clamp from vehicle chassis, and then remove clamp from battery
terminal.
using the Alternator Check Function
Set up the battery charger and connect to the battery following steps 1 through 2 in the “Charging the Battery” section.
Part 1
No Load (turn OFF all vehicle’s accessories):
The battery must be fully charged before testing the alternator. Run the engine long
enough to achieve normal idle speed and verify there is a no-load voltage.
1. Press the alternator check button to start the check. The LCD screen will display the following to indicate the unit is analyzing
the alternator:
The pump engine icon and the half-full battery icon will flash.
2. If the unit detects that the alternator is good, the LCD screen will display the following:
The pump engine icon will light solid, and the bars on the battery icon will change from empty to solid (bottom to top)
repeatedly.
3. If the unit detects that the alternator is out of typical voltage range, the LCD screen will display the following:
The half-full battery icon will light solid and the triangular alarm icon will flash.
4. Press the alternator check button again to stop the test.
Part 2
Under Load (accessories ON):
Next, load the alternator by turning on as many accessories as possible (except for A/C and Defrost).
1. Press the alternator check button to start the check. The LCD screen will display the following to indicate the unit is analyzing
the alternator:
The pump engine icon and the half-full battery icon will flash.
