Troubleshooting
Setup and Operation
Note: When working with tools near electricity serious electrical shock can occur resulting in injury.
Install your ProMariner battery charger by referring to page 8 of this manual.
After installation is complete including AC and DC connections, please ensure proper fusing, strain
relief and cable support has been performed.
1) Turn off all power to the charger and disconnect all the DC cables at the batteries
making sure that no cables are in contact with equipment, other wiring, or one another.
2) Set the battery type rotary switch to position number 6
3) Apply AC power. Allow 30 seconds for the charger to produce the correct voltage. This
is part of the soft start technology. The charger will be in Fast Charge Mode then Absorption
Charge Mode. Use a multi meter to check the voltage between each positive and the
negative lead. The meter should read a voltage of 14.7 -14.8 volts DC.
4) If the voltage is correct 14.7 -14.8 keep the charger AC power on but disconnected from
the batteries. Leave the charger on for approximately one to two hours or until float mode
is observed. The voltage should drop to 13.3 indicating float mode.
5) If you see all of the above voltages, your charger is working correctly.
6) If you don’t see the initial 14+ volts, the charger either has a blown fuse or circuit board
failure. Please contact ProMariner Customer Service 1-800-824-0524 or email:

4) Battery cables, connections and installation must comply with ABYC E-11 standards.
We recommend that each ungrounded DC conductor (Positive cable) be provided with
an over current protection fuse within 7 inches of connection to the battery or battery
connection point. The fuse rating should be at least 10 amps higher than the rated full
output of the charger. See ABYC E-11 for specific requirements. Over current protection
within 7 inches of the charger is not required as the ProNautic is self limiting and can not
exceed its rated current output. The internal fuses protect the unit against reverse polarity.
Two Bank Installation (FIG.2)
Same as three bank leaving one output post
without a connection.
Note: Circuit Protection should be attached
to each positive charger lead 7 inches from
the battery or the battery connection point

(ABOVE) It is recommended that a jumper(s) be used between unused positive output post(s)
and a used post connected to a battery. Please note you can connect all three positive posts
together to form a single bank connection.
All DC wire terminations and connections must be made in compliance with ABYC E-11 & A-31
