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. 22863-4 ‰ 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. 22826 If any of the malfunction conditions continue to exist after completing the steps above, see your authorized Volvo Penta dealer for further service. 96 VPA 7743722 English 10-2004
