complete failure shortly thereafter.  Heavily
discharging (over 60%) new batteries before
they have been broken in (approximately 20
cycles) can cause permanent cell damage,
resulting in reduced energy capacity and
shortened life.

6.

Maintain the proper electrolyte level by adding
water when necessary.  Never allow the
electrolyte level to fall below the top of the
battery plates.  Electrolyte levels fall during
discharge and rise during charge.  Therefore, to
prevent the overflow of electrolyte when
charging, it is mandatory that water be added to
cells AFTER they have been fully charged; do
not overfill.  Old batteries require more frequent
additions of water than do new batteries.

7.

When the temperature falls below 65

°

F, the

batteries should be placed on charge as soon
after use as possible.  Cold batteries require
more time to fully recharge.

8.

The tops of the batteries and battery hold-downs
must be kept clean and dry at all times to
prevent excessive self-discharge and flow of
current between the battery posts and frame.

9.

Follow all operating instructions, cautions, and
warnings as specified in this manual, on the
charger, and in your vehicle owner manual.

TROUBLESHOOTING GUIDE

To be able to use the troubleshooting guide
safely and effectively, it is important to read this
guide completely before beginning any tests.

CAUTION:  REPAIRS BY QUALIFIED

PERSONNEL ONLY.  NOTE -- MODIFYING THIS
CHARGER FOR USE OTHER THAN THAT FOR
WHICH IT WAS INTENDED, REPAIRS BY
PERSONS NOT QUALIFIED, OR NOT USING
ORIGINAL EQUIPMENT REPLACEMENT PARTS
WILL VOID THE WARRANTY AND LESTER
LIABILITY.

CAUTION:  DO NOT DISASSEMBLE THE

CHARGER.  TAKE IT TO A QUALIFIED SERVICE
AGENT WHEN SERVICE OR REPAIR IS
REQUIRED.  INCORRECT REASSEMBLY MAY
RESULT IN RISK OF ELECTRIC SHOCK OR FIRE.

DANGER:  HIGH VOLTAGE!  WITH THE

CHARGER ON, THE INTERNAL CHARGER
CAPACITOR VOLTAGE IS APPROXIMATELY 650
VOLTS.

CAUTION:  ALWAYS UNPLUG THE

ELECTRICAL PLUGS FROM THE AC OUTLET

AND THE BATTERIES BEFORE ATTEMPTING
ANY REPAIRS TO THE CHARGER.

WARNING:  DO NOT OPERATE THE

CHARGER IF IT IS MALFUNCTIONING.
PERSONAL INJURY OR PROPERTY DAMAGE
COULD RESULT.

The Lestronic II battery charger is a reliable,
automatic charger designed for long, trouble-free
service.  If a malfunction should develop, identify the
symptom and follow the associated test procedures.

SECTION

MALFUNCTION SYMPTOM

1

CHARGER DOES NOT TURN ON

A. Relay does not close, no transformer hum, and

ammeter does not register.

B. Relay closes but no transformer hum and

ammeter does not register.

C. Relay closes and transformer hums but

ammeter does not register.

D. Electronic timer kit replacement instructions

2

CHARGER FUSE BLOWS

A. Single fuse link blows.

B. Both fuse links blow.

3

AMMETER READS 30 AMPS FOR MORE THAN
30 MINUTES

4

CHARGER OUTPUT IS LOW

5

CHARGER TURN OFF MALFUNCTIONS

A. Charger turns off too soon.

B. Charger does not turn off.

C. Charger runs too long but does  turn off.

6

AC LINE FUSE OR CIRCUIT BREAKER BLOWS

7

TRANSFORMER SHORT OR BURN-OUT

SECTION 1 – CHARGER DOES NOT TURN ON

In normal operation, the charger DC output
connector must be connected to the batteries in
order to turn the charger on.  A time delay of two to
five (2-5) seconds is provided to allow adequate time
to make a secure connection before the charger
turns on.  After this time delay, the power relay
closes and an audible "click" should be heard.
When the relay closes, AC power is supplied to the
transformer primary coil.  If operating properly, the
transformer should hum and the ammeter should
indicate the charge rate.  If the charger does not turn
on properly, refer to Part A, B or C for specific test
procedures.

Part A Relay does not close, no transformer

hum, and ammeter does not register

Check to be sure the power supply cord is securely
connected to a live outlet.  Check the DC output
connector and the battery connector for damage, dirt
or corrosion that would prevent a good electrical
connection.
