(a) With caps securely in place, thoroughly clean the case and posts with a solution of baking soda
and water. Be careful not to allow any baking soda to get inside the case.
(b) All posts, terminals, and connectors should be cleaned to a shiny bright finish, using a wire brush
or sand paper. This should be done periodically to assure maximum conductivity between the
battery and the charger.
To connect the charger to the battery (batteries), route your charge cables from the charger to the
batteries, being cautious to avoid sharp objects, and use the supplied wire ties to hold them securely and
neatly in place.
Securely attach each charge cable independently to one 12V battery by connecting the red (po)
lead ring terminal to the positive (+) battery post and the black (negative/-) lead ring terminal to the
negative (-) battery post. See picture below:

The charger pictured
is a Professional Series
Dual Pro, which has two
independent 15 amp outputs.
In addition, your charging system is supplied with an AC plug receptacle designed to hold the power cord
plug when it is not being used. Locate a convenient site for the receptacle and attach it using the
supplied four smaller stainless steel screws.
Connect a heavy duty UL approved extension cord to the power cord of your charger and then plug the
extension cord into a nearby 120VAC GFI protected (Ground Fault Circuit Interrupt) outlet.
You should now observe a red LED indication on each bank of the charger representing each individual
battery being charged. The voltage of each battery will reflect the number of LED indicators illuminated.
When charging is complete, remove the extension cord from the 120VAC outlet first and then unplug the
charger.
TROUBLE SHOOTING
PROBLEM: No LED indicators illuminate in any of the charger banks.
Solution Sequence: Check the AC power supply from its source through all connecting points up to the
charger by using a meter or test light to confirm that current is being delivered to the charger.
PROBLEM: One red LED indicator flashing.
Solution Sequence: With the AC power supply cord unplugged, check the ring terminals for correct
polarity (Red to positive or +) and (Black to negative or - ). Also check for corrosion free secure
connections to the batteries. Check in-line fuses in charge cable for any signs of opening or corroded
connections. Call the technical support group for further assistance (800.742.2420).
PROBLEM: The green LED will not illuminate after excessive charging time (16 hours or more).
Solution Sequence: Disconnect AC power to the charging system. On multi bank chargers, remove the
charge cable assembly of the affected bank from the battery and attach it to another battery in the boat.
Take the original charge cable assembly from this battery and attach it to the battery from which you
removed the first cable. Plug the charger in and observe the LED indications. If the same problem
occurs on a different bank of the charger, this confirms the existence of a battery problem.
