SJM & SJII Series
If the “80% CHARGE” light continues to stay on after
the charge cycle is complete, this indicates to the op-
erator that the batteries are not capable of attaining a
full charge.
If the “INCOMPLETE” light remains on after the charge
cycle is complete, this indicates to the operator that
the batteries are not capable of attaining even an 80%
charge.
If either the “80% CHARGE” or “INCOMPLETE” light re-
main on after the charge cycle is complete, the batter-
ies should be inspected for problems.
Refer to the “Battery Service” section for proper battery
inspection and maintenance procedures.

This charger is equipped with an electronic circuit that
will completely recharge the batteries and automati-
cally turn off after the charge cycle is complete.
The function of the L.E.D. indicators is as follows:
When the AC power is connected to the charger, the
L.E.D.’s will flash several times then flash independently
to check the light circuits. After the flashing sequence is
complete the “INCOMPLETE” light will come on. Five
seconds later , the “CHARGER ON” light will come on
and at the same time, the ammeter will indicate how
much current is going to the batteries.
As the charge cycle continues, which can last between
1 1/2 hours and 16 hours for a complete cycle, de-
pending on the state of charge of the batteries, the
“80%” light will come on and the “INCOMPLETE” light
will go off. When voltage of the batteries reaches ap-
proximately 30 volts, the “80%” light will go off and the
“CHARGE COMPLETE” light will come on. This light
will remain on even after the charger is turned off by the
electronic control. After the charger turns off, the
“CHARGE COMPLETE” light will indicate to the opera-
tor that the batteries are fully charged.
