SECTION 5 |
When the batteries are discharged, they will draw charging current proportional to
their discharged condition (up to the maximum current rating of the charger) and this
current draw will be shown by the Ammeter. When the batteries are fully charged, they
will draw very low current (may not be registered by the Ammeter) to compensate for
their self discharge.

5.3.1 Charging a Battery Installed in a Vehicle
Follow these steps when the battery is installed in a vehicle. A spark near a battery may
cause battery explosion. For safety and to reduce the risk of spark near the battery:
a) Position AC and DC cords to reduce risk of damage by hood, door or moving engine
parts
b) Stay clear of fan blades, belts, pulleys and other parts that can cause injury to persons
c) Check the polarity of the battery posts. A Positive (Pos, P, +) battery post usually has a
larger diameter than a Negative (Neg, N, -) post
d) Determine which post of the battery is grounded (Connected to the chassis Engine
Block). If the Negative post is grounded to the Engine Block (As in most vehicles), see
sub paragraph (e). If the Positive post is grounded, see sub paragraph (f).
e) For a Negative grounded vehicle, connect the Positive (Red) DC wire from the charger
to the Positive of the battery post. Connect the Negative (Black) DC wire from the
charger to a section of heavy gauge metal part of the frame or engine block which is
away from battery. Do not connect to carburetor, fuel lines or sheet metal body parts.
f) For a Positive grounded vehicle, connect the Negative (black) DC wire from the charg-
er to the Negative of the battery post. Connect the Positive (red) DC wire from the
charger to a section of heavy gauge metal part of the frame or engine block which is
away from battery. Do not connect to carburetor, fuel lines or sheet metal body parts.
g) Connect the charger AC power cord to the AC outlet
