Lenco actuators come with 6FT actuator cables that feature Deutsch terminations.
Boat builders may use a separate wire harness connecting power and actuators to control box.
If you’re not certain if there is a separate connection in your boat, contact the boat manufacturer.
This guide is intended to provide basic functional diagnostics and will assist in determining
the source of the problem. Choose Power Fault or Actuator Fault and follow the steps.
