Part I. General Troubleshooting
Case I. The motor is making erratic steering corrections while in AutoPilot,
Spot-Lock, or Track to Start/End.
Step 1. Check all electrical connections and battery condition to ensure that the proper voltage is supplied to the motor.
Consistent voltage is critical to ensure the built-in compass is working correctly. (The i-Pilot system uses an
internal compass to know which direction the controller and GPS receiver is pointing.) A load test of the
battery should be performed to verify the battery(s) condition; a simple voltage check is not diagnostic.
Step 2. Be sure to keep all ferrous metallic objects away from the i-Pilot Controller as they will have an impact on the
built-in compass. Such objects include: anchors, metal framework, etc…
Step 3. Check to ensure proper motor leadwire routing in control box.
A. The red and black motor leads in the control box should be routed on the coil cord half of the control
box. (Away from the compass of the i-Pilot controller.)
B. The red and black motor leads in the control box should be twisted around each other to cancel out the
magnetic field created around these wires when the motor is running.
B-1. If the motor shaft was shortened, the brush leadwire should also be cut back the same length.
B-2. If the motor shaft was shortened and the motor has a built-in transducer, the extra transducer
cable should be routed out of the control box and down the coil cord.
(Note that the red/black wires should be twisted three times on both the coil cord and brush leadwire sides and
then the insulator or shrink tube is slid in place over the spade connectors. This picture shows an
Ulterra, but the wire routing is similar and critical for all motors with i-Pilot.)
Step 4. The i-Pilot GPS-based functions are dependent on having good GPS signals (Advanced AutoPilot, Spot-Lock,
Track to Start/End). Check to make sure that a good signal is being received and that the GPS signal strength
indicator on the i-Pilot remote is showing at least one (1) bar. See
Case V below.
Step 5. If the motor with i-Pilot being serviced is a 2017 or later model (Bluetooth version):
A. If motor has a separate Heading Sensor , it is very important that the Heading Sensor is properly
installed and has gone through the calibration and offset procedures. While the Heading Sensor is
there to help with navigation performance; if it is not properly installed/calibrated it can have a
negative influence.
A-1. Temporarily remove power from the Heading Sensor and see how Spot-Lock performance is
impacted. If performance is improved, suspect that the Heading Sensor was improperly
installed. (The Heading Sensor contains a compass that detects a magnetic field so it should
not be installed near ferrous metals or wires that handle large currents, such as batteries,
power cables, or speakers.) The Heading Sensor will not lose it pairing to the i-Pilot system
when it is powered down.
B. Boat Scale can be adjusted on the i-Pilot remote.
B-1. Ideal installation for a trolling motor is to have the proper amount of thrust for the size of the
boat. If the motor thrust is not properly matched to the boat size, Boat Scale can be used to
compensate for the mismatch. The default is zero, assuming that the boat and trolling motor
thrust are properly matched. For an installation where the motor thrust is undersized for the
boat, increase the Boat Scale. For installation where the motor thrust is oversized for the boat,
decrease the Boat Scale.
Step 7. If, after following the previous steps, the problem of erratic steering persists replace the i-Pilot Controller.
