L OUTPUT CURRENT SELECTOR SWITCH
In addition to the voltage selector switch, some models are equipped with a two position
switch, allowing the operator to select the ampere charge rate to a battery, as follows:
MODELS
WS or SE- or SEC- SWITCH SETTING
82-6 6 or 2 Amps (Trickle)
1010-2 10 or 2 Amps (Trickle)
1015 15 or 3 Amps (Trickle)
1020 20 or 3 Amps (Trickle)
-
Before making any connections to battery, read instructions F, G and H carefulIy.
Connect DC output clips only when AC power supply cord is removed from electrical
outlet.
Never allow cilps to touch each other.
M. CHARGE PERIOD: The approximate required time to bring a battery to full charge state
depends upon the number of ampere hours (AH) depleted from the battery. AH’s are
determined by multiplying the number of hours times the number of Amps supplied by a
battery to a load.
For example - If a load was connected to a battery, which drew 7 Amps for a period of
5 hours, the battery will have supplied 35 AH. The approximate recharge time would then
be calculated by dividing the 35 AH depleted from the battery, by the ampere charge rate
of the charger. To allow for tapering of the charge rate add 25 percent to the charge time.
Indications of a fully charged battery are:
When the ammeter indicates the charge rate has tapered to approximately one half the
charger rated output.
A hydrometer reading of the specific gravity of the electrolyte (fluid) of a battery in good
condition should be between 1.250 and 1.285.
When a battery reaches 80 - 85% of full charge bubbles will appear on the surface of
the fluid. As the battery nears full charge, bubbling will become more noticeably
vigourous.
Disconnecting from Battery:
Before disconnecting from battery read instructions F. G and H carefully.
N. STORAGE: Store battery charger In a dry area.
O. PROBLEM CHECKLIST
1. If no meter reading, check the following:
a. Remove the charger power cord plug from the AC outlet and recheck the battery
charger clips for clean, tight connections.
b. Check voltage selector switch for proper setting.
c. Check for voltage at the AC outlet by plugging in a lamp or other appliance.
2. If Ammeter pointer moves to extreme right, remains a short time, then returns to zero,
accompanied by a cilcking sound, check the following:
a. Possibly, the charger connections are reversed. (Positive to negative, instead of
positive to positive).
