3. If only the red LED (
3
) is illuminated, the drive is
not adequately protected and may have one of
the following conditions:
Water too severely contaminated or polluted.
Install additional anode on the transom and
ground to drive unit.
Too much unpainted metal on the drive or
transom shield. Clean and paint exposed
metal on drive and transom shield. Please re-
fer to the section entitled
Propeller Care
on
page 98 for paint repair procedures.
Corroded, missing, or painted anodes. Serv-
ice or replace anode as required.
Stray current from shore power or surround-
ing boats. Disconnect shore power, wait 8
hours and recheck. If still present, temporarily
relocate boat to another area away from the
marina and check again.
Loose or corroded terminals on the electronic
unit or battery. Clean and tighten connectors.
Copper bottom paint used and is in contact
with the transom shield. Remove paint and
ensure there is a 25mm (1 in.) border be-
tween transom shield and bottom paint.
4. If no LEDs are illuminated (
4
), the unit is not
receiving power. Check the following conditions:
Dead battery. Check battery condition and
charge as necessary.
Loose connection or corroded terminals on
the electronic control unit or battery. Clean
and tighten the connectors.
Blown fuse. Replace defective fuse. The fuse
(
5
) is located near the battery connectors.
Broken anode or reference sensor unit. Re-
place damaged unit. Follow the installation in-
structions included with the replacement unit,
or see your authorized Volvo Penta dealer for
service.
NOTE!
The active corrosion protection system is
designed to adequately protect one drive
unit from galvanic corrosion under normal
operating conditions. This system will not
provide protection from stray currents emit-
ted by a malfunctioning AC power source on
your boat, the pier, or other boats in close
proximity to yours. Although the zinc sacrifi-
cial anodes will last much longer with this
system, they must still be cleaned and
checked for material condition periodically.
If any of the malfunction conditions continue to exist
after completing the steps above, see your authorized
Volvo Penta dealer for further service.
