I recently ditched the wheel
pilot on my Pearson
424 and installed a B&G autopilot
setup with a B&G T2 linear actuator and a NAC-3 computer. Over the weekend I got it to the point where the system was read to test. After going through the setup the pilot tries to test the rudder
feedback by powering the ram and moving the wheel
When I do this test, the pilot computer provides power to the motor
on the T2 ram but nothing happens. The clutch
does make a clicking noise
but beyond that I'm not sure how to test that it is engaged. Although I can measure the amps being consumed by the motor
on the linear actuator, it doesn't make much noise
or vibration. The amps steadily rise in the motor circuit during the init test and once they hit 40 or so the unit gives an overload alarm
. At no point does the ram move at all.
diagram is crappy so I switched the polarity on the clutch
engage circuit. The solenoid still clicks but the unit still overloads without moving the rudder
. I wouldn't think the polarity of the motor leads matters considering it is reversible.
The wheel is easy to turn from stop to stop so doesn't seem to be mechanically stuck.
Going to reach out to B&G support but thought I'd see if anyone ran into something similar. I guess the primary question is would this be the expected behavior if the clutch wasn't engage? Is there a way to test the clutch beyond listening for the click? I could try turning the wheel with the clutch engaged?
