Tightly twist the strands for the RED wire together, and insert in the
opening marked ( + ). Solder and trim the red wire.
The other end of the married RED/BLACK cable will be used to connect the
battery pack to the charger. At this time you may wish to provide a suitable
connector to mate with the battery pack the charger is to be used with. The red
lead connects to the positive battery termination, the black lead connects to the
negative battery termination.
This completes the assembly of the VEC-412K Rapid Charger/Battery
Conditioner. Before proceeding, please take some time for a quality-control
inspection. Carefully verify that all parts are in the correct locations. Check
each solder joint for unwanted bridges. Correct any poor solder joints.
TESTING
Performing a test of the VEC-412K Rapid Charger/Battery Conditioner requires
a good understanding of what the various switches and jumper settings are used
for. We suggest reading the Operating Instructions on page 20 of the manual
to become familiar with the unit’s operation and setup procedures.
1. Select a battery pack that is known to be in good condition for the following
tests. Power must be supplied from an external source—the current and
voltage requirements are dependent on the battery pack to be tested. Set the
shorting jumpers on headers HD1, HD2, HD3, HD4, HD5 and HD6 as
directed in the Operating Instructions.
2. Set range switches SW3 and SW1 to correspond to the number of cells in the
test battery pack (see Table 1).
3. Connect the RED battery charger lead to the positive battery terminal.
Connect the BLACK battery charger lead to the negative battery terminal.
4. With the power supply connected, turn power switch SW2 on. The RED
status LED (CR1) should indicate either Fast Charging or Charger
Pending.
A Charger Pending status indication occurs when the battery pack is in a
discharged condition (less than one volt per cell). At this point, the charger has
initiated a trickle charge which will continue until each cell reaches a 1-volt
charge. If the battery pack was charged before hand, and the Charge Pending
