CAUTION: NEVER ‘ROCK’ OR ‘WALK’ THESE TERMINALS TO GET THEM ON OR
OFF OF THE RELAYS. USE A ‘DIRECT’ IN/OUT MOTION WHEN INSTALLING AND
REMOVING THESE TERMINALS.
The goal is to minimize widening or spreading of the ‘curl’ of the female terminal that reduces
the clamping strength and area of surface contact with the blade in the relay. Use large
needle-nose pliers or similar tool that you feel comfortably in control of to remove and install
these quick disconnect terminals from the relay blades.

The charger operation may be checked by first connecting the DC output plug to the battery
receptacle, and then connecting the AC input cord to a live outlet. If the transformer hums and
normal charging current is indicated on the ammeter, the electronic charge controller is
defective and must be replaced.
CAUTION: DO NOT CHARGE BATTERIES WITH THE ELECTRONIC CHARGE CON-
TROLLER BYPASSED. THE CHARGER WILL REMAIN ON AS LONG AS THE AC INPUT
CORD IS CONNECTED TO A LIVE OUTLET. SEVERE OVERCHARGING AND EVENTUAL
DAMAGE TO BATTERIES WILL RESULT.

Not Turning Off
The electronic charge controller has a built in maximum timer, which will turn the charger off if
it has run for 16 hours. The actual time may be longer than this if the AC input voltage has
been off during part of a charge cycle. Connect the AC input cord to a live outlet, then check
to see if the charger turns on immediately without the normal three to five (3-5) second delay
when the DC output cord is connected. If the charger turns on instantly, the electronic charge
controller relay contacts have probably failed closed. This type of malfunction results in the
charger not turning off.
CAUTION: DISCONNECT BOTH AC INPUT AND DC OUTPUT CORDS FROM ALL
POWER SOURCES BEFORE YOU PERFORM THIS TEST.
