Further to earlier question, Lockie, I see that you've commented that "Raymarine ST1000/2000 tiller pilots have no end-of-stroke protection ..." and that you fitted limit switches. I can't find any position measuring electronics in the linear actuator - that is, I see no photo interrupters or hall sensors or others to make a rotary encoder possible. Do you happen to know how position of the actuator is monitored. The gearbox looks pretty tied for adding an encoder.
Hi Lockie, I found your post about your ST2000 problems. Did you ever get it sorted? I have 3 (2 * 2000, 1 * 1000) that I want to resurrect. I'll try cleaning the boards first. But as I've been doing a bit with Arduino and controllers recently, I'll be trying that if cleaning doesn't sort things out.
