PowerTech MB3616 Instructions For Use Manual

Troubleshooting
AC Power LED (blue), Charge Mode LED or Charge Monitor LEDs are not ON.
Check for loss of AC power at the 240 VAC outlet. Confirm GFCI (Ground Fault Circuit
Interrupter) has not tripped. Check with a meter or 240 VAC test light that AC power is present
at the end or in 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 connec-
tions are clean and tight. Wait for 2 minutes until the unit completes analyzing stage.
System Check OK LED (green) is OFF and Troubleshoot LED (bank1, bank2 or
bank3) is ON (red).
Identify the battery bank LED that is lit, remove AC power and check the battery bank indicated,
for example bank 1, bank 2 or bank 3 (model specific). The LED indicates there is a fault
present. Below are listed typical faults and instructions on how the fault status can be solved:
Note: After making any corrections, reapply AC power.
Poor battery connections - Make sure all connections are tight and clean.
Blown DC cable fuse - Use the ohm meter or continuity tester to make sure all
fuses are healthy and visually inspect the DC battery cables to ensure they have
not been compromised or shorted in any manner.
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 - Using a digital voltmeter, make sure the battery is over 2.5 volts
DC. If not, have your battery charged out of the boat and have it load tested by your local
battery dealer to ensure it is safe to charge and that the battery is capable of holding a charge.
High battery voltage input - Make sure a bank lead has not been spread across 2 batteries
connected in series for 24 volts DC. If so, correct by following the wiring diagrams on pages 13-20.

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
Battery 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:
