Navico Tillerpilot TP200cx (Simrad TP20) blocking problem


I have Navico TP200cx with which I have two problems – both are somehow connected to locking the moving arm in certain positions or conditions (at least I suppose).

The first issue is that it locks itself at max and min arm extension points. If that happens the only way to fix it is to open the body and push the arm accordingly. I learned how to avid the issue by putting some marks on the extending arm to avoid extending or reducing it too far and now not having the issue. I am writing about it because it could be a hint for the second issue.

The second problem is while it works in auto mode it sometimes stops working and just before that it makes 3 sounds like “wheeee-wheeee-wheeee” which probably are last desperate try to move the arm.

Initially I though that it was somehow connected to high temperature because I started to notice this problem during warm days while sun operated directly onto the body of TP20. I was trying to cover it with some white cloth. Is sometimes helped but I cannot clearly tell if high temperature was the issue.

Last season I started to have the problem even on cold days. I suspected that it could be connected with low current supply from my battery or cables being to thin – I checked the cables, and replaced last few inches of them going from the connection cube to the cockpit socket (I think that the rest of the cable should be ok but not sure though). However the problem persisted. I opened the device several times to unblock it (first issue) and there was never any sight of prior water ingress – the overall look of the device is ok.

I suspect now that maybe the issue is directly connected to the friction which is too high for the motor to move the arm or maybe the belt is too loose or too old or … I do not know.

My boat is rather light on the rudder, so I don’t think that high opposite force from the tiller is the source of problem.

Anyone here had similar problem with these devices and found solution?
