Continuity Circuits
NOTE: Refer to the operation and maintenance manual provided by the boat manufacturer
for maintenance information about vessel mounted anodes and related continuity circuits.
The drive system is equipped with ground circuit wires to ensure good electrical continuity
between the drive components. Good continuity to a ground (–) is essential for the anode
and MerCathode system to function most effectively.
1. Remove the drive cover. Refer to
Removing the Drive Cover
in this section.
2. Inspect the MerCathode controller and wires for loose connections, broken
connectors, or frayed wiring.
