Auto pilot problems
I'm having problems with my auto pilot. It is a Auto Helm ST70 type 300.
It started crapping out a couple of weeks ago. Sometimes when I turn it on, the control panel for the autopilot is blank. Sometimes it is blank and there is a alarm squealing. Sometimes it works. Sometimes I can turn it off and back on again and it starts working again. Or at least it used to. Now I think it is just in the blank display with squealing alarm mode. All my other instruments seem to be ok.
Has anybody ever seen this sort of problem before?
My first thought it that is a loose connection somewhere. Maybe low power.
It tried to reseat the power coming into the main computer. But I'm a little confused how the wire clamps are supposed to work. There are big ones and little ones. The little ones are obvious. There is a tab above the wire hole. You depress the tab and the wire is released. Let go of the tab and the wire is clamped. There are a couple of big clamps for power input and out to the drive motor. These don't have a tab. I'm not sure how to release the wire. I tried a couple of things but I didn't want to push to hard and break something.
Does anybody have any tips?
