TROUBLESHOOTING
No Blue AC Power LED or Charge Mode LEDs
Check for loss of AC power at the 120 VAC outlet. Confirm GFCI (Ground Fault Circuit Interrupter)
has not tripped. Check with a meter or 120 VAC test light that AC power is present at the end or
your extension cord. Reset AC power if it was not present. Confirm all charger cables are installed
with the correct polarity connections at each battery and that all connections are clean and tight.
Wait 1 minute while unit completes its analyze mode. If AC power is present and all connections
are correct and LEDs do not illuminate, contact Guest

Red Battery Bank Trouble Status LED is ON.
Identify the battery bank LED that is lit, remove AC power and check the battery bank indicated i.e 1, 2, 3 or 4
(model specific). The LED indicates there is a fault present. Listed below are typical faults and what can be done
to clear the red battery bank trouble status indicator (reapply AC power after making any corrections):
Poor battery connections
- Make sure all connections are tight and clean
Blown DC cable fuse
- Make sure all fuses are good with a digital ohm meter or continuity
tester and visually inspect the ChargePro
™
Series's DC battery cables to insure they have not
been compromised or shorted in any way.
Reverse polarity
- Make sure all wiring connections are color coded and connected
properly and that each bank cable goes to one 12V battery where (+) = red and (-) = black.
Battery too low to charge
- with a digital voltmeter make sure the battery is over 4.0
volts DC (if not have your battery charged out of the boat and have it load tested by your local
battery dealer to insure it is safe to charge and that the battery is capable of holding a charge).
High battery voltage input
- Check to make sure one bank lead was not spread across 2 batteries
connected in series for 24 volts DC. If so correct by wiring to the diagrams on pages 14-23.
Battery(s) not charging, Blue AC Power LED, RED Charging LED is ON
Confirm all charger cables are installed with the correct polarity connections at each battery, and
that all connections are clean and tight. Confirm that there are no bank trouble status LED indicators
on. With the charger on, read DC voltage at each battery. If any of the readings are less than 12.8
volts DC proceed with the following:
A. Disconnect AC power at the 120 VAC outlet.
B. Go to pages 14-23 of this manual and confirm your ChargePro
™
Series model charger
is connected correctly as illustrated in the installation drawings.
C. Upon completing B above; plug your charger into AC power and observe the LED display.
Charger should be in the charging mode (charge mode indicator should be red). After
completing a full charge cycle, 10-12 hours or more for deeply discharged or completely
dead batteries, the green Auto Maintain LED will illuminate in addition to the blue AC Power LED.
Note: If a Digital Volt Meter (DVM) is available to you, instead of waiting to complete a full charge cycle, you can simply use a DVM
and take DC voltage measurements across each 12 volt battery. As long as the voltage continues to increase while the red charging
LED is on, this will serve as a confirmation that the charger is properly connected and is properly charging.
