Troubleshooting Continued
3) If the Voltage is correct keep the charger powered up but disconnected from
the batteries number of hours as set by the (S1) dipswitches (shown on Page 4)
The green LED should become illuminated. Recheck the Voltage; it should be 13.5
Volts Lead Acid and 13.5 Volts for GEL from each positive lead to the negative lead.
4) If you see all of the above, your charger is most likely working correctly.
5) If you do not see the initial 14+ Volts, the charger either has a blown fuse, or circuit
board failure. Turn off AC power; remove the small cover and the large cover with
the fan. The fan and the AC (120 Volt or 240 Volt) terminal block are attached to the
main circuit board. There is a glass cylinder fuse (AC fuse) if it is blown replace it (the
fuse says 250 Volts- however if your boat doesn’t leave the United States and is a 30
Amp service. It can replace with a 120 Volt same amperage fuse. If it blows a second
time then a circuit board failure has occurred.

Three Bank Wire Installation
A) Batteries negative wires are run separately
to the boats DC bus bar (not provided). Then a
single connection is made to the chargers
negative stud.
B) 3 separate positive wires attach to the 3
positive posts on the charger.
Two Bank Installation
When wiring for two batteries you will need to
use the jumper wire provided. The jumper goes
on the unloaded positive terminal and connects
to an adjacent positive terminal (Note: do not
leave a terminal post unloaded).
One Bank Installation
(See above) Use the provided jumper wire
and create another. We recommend crimped or
soldered connections and 14 AWG wire. (Note:
do not leave a terminal post unloaded).
