52 ST4000 Plus Wheel & Tiller Autopilots Owner’s Handbook
Note: Use of the correct cable size is critical for correct autopilot
operation.
If the cable is too small, a voltage drop will occur between the supply
and the control head. This will reduce the power to the drive, causing
slower response to course changes and corrections.

Because different installations have different cabling requirements,
SeaTalk cables are not supplied with the ST4000 Plus ñ cables must be
purchased from your Autohelm dealer.
