4.5 Battery Charger
Troubleshooting
Use the battery charger’s LED indicators and the table in
Figure 4-3 to troubleshoot battery charger operation
problems.
Problem Possible Cause Corrective Action
Controller LED display

No power to the controller:
Continuous power mode jumper is disconnected
and the generator set has not run for 48 hours or
longer.
Controller display will automatically activate when a remote
start command is received or the generator set master
switch is moved to the RUN position. See Section 2.5.
Connect the jumper to maintain continuous power to the
controller, if desired.
Controller fuse (F3) is blown. Replace the fuse. If the fuse blows again, contact the
distributor/dealer.
Low or no battery voltage. Check connections.
Check generator set battery and battery charger. See
Figure 4-1.
Generator set master switch is in the OFF/RESET
position.
Move generator set master switch to the AUTO or RUN

Battery charger has reduced its output voltage below
the normal level due to a DC overload or a DC short.
Remove the source of the overload or short. Disconnect the
battery charger’s black (NEGATIVE) ring terminal from the
battery. Reapply AC power and the green LED only should now
light.
Onboard DC systems are drawing more current than
the battery charger can replace.
Turn off all DC equipment while charging.
