Lenco 100 Series 9×9 Kit 15000-101 wiring diagram

15000-101 is the 12 V 100 Series standard-mount kit with two 9 × 9 inch trim-tab blades, two actuators, extension harnesses and mounting hardware. It does not include a switch kit. A trim-tab installation needs controls suited to the actuators and desired functions before its wiring can be finalized.

Lowering a tab increases lift at that side of the stern. The control labels describe the desired bow movement, so the left side of the helm control operates the opposite tab. This is why actuator connector identification matters even when both motors move successfully.

The catalog's positive and negative terminals represent the supply to a future compatible control assembly. They are not instructions to connect the actuator leads permanently to a battery. The controller reverses actuator motion and, on applicable controls, manages automatic retraction.

For the standard integrated 15169-001 single-actuator-per-tab arrangement, the 2023 manual's p. 12 diagram specifies 20 A fuse or breaker protection at 12 V. It also shows the separate orange retract-sense lead connected to an on/off source, with the main red/black supply arranged as drawn. Do not assume that simply interrupting the main feed preserves automatic retraction. Other controls have their own diagrams.

The 20 A figure is a protection choice for that example, not measured running current. Both operating draw and surge remain unset until the actual controls and load are established. The terminal limit is a planning bound, and verification remains family-only for the unselected control circuit.

Use the standard-mount dimensions and the table for a 9-inch blade; edge-mount dimensions belong to another kit. Check inside the transom before drilling. Support the upper bracket in its natural alignment with the actuator and blade so the mechanism does not bind. Seal fasteners and cable penetrations using the manual's gland and bedding arrangement.

Route the provided actuator extensions to the selected control location, preserving Deutsch connector pin positions and the port/starboard identification. Allow service access. Do not substitute a guessed battery-feed cable size for the manufacturer's actuator harness requirements.

With the vessel secure, confirm each bow-labelled command moves the intended tab in the correct direction. Check complete travel without binding and verify the chosen controller's retract behavior. At sea, make short adjustments and observe the boat's response; avoid a large one-sided command at speed and retract the tabs in a following sea as instructed.

For a failed side, inspect its connector and harness before replacing the actuator. For faults on both sides, check the control supply and protection. Periodically inspect brackets, seals, anodes and the stainless surfaces; corrosion resistance does not remove the need for maintenance.
