[CA] [CA11] Autopilot Malfunction

[borghetti]

Hello guys,

We have been thru the FAQs in search for a solution for the problem we are facing now, we tried some solutions already
but the fact is that we may have an important point to check before going for any troubleshooting. I will explain.

I must start by telling my father just bought a 2001 Jeanneau DS which had been struck by a lightning 5 years ago.
The previous owner then put an all new SeatalkNG network and Raymarine equipments that I will add to this post.

The previous owner said he paid for an authorized Raymarine Technician, and everything looks fine and appears
to work properly but we still have a problem with the Autopilot working erratic.

When engaged, the AP works for a couple random minutes then it simply stops working, helm stays in that last position,
no more TICTIC from the drive working and, as the boat steers away from the AP course with helm locked, then we get the
alarm of "Drive Stopped" or "Off Course" warning in the screen and consequent disengage from auto, which unlocks the helm.

We had these two different warnings randomly, and we thought about it, maybe if it was due to a faulty drive back there,
then the Dockside Wizard would also have problems turning the helm like the autopilot does, but it does it fine and steady.
I must add here that our rudder position transducer is working and displaying port and starboard correctly!

By reading the FAQs here I could find that our Max Deviation was at alarming 188 degrees, so we went for hours of cruising,
with 360 turns and 8 figures, but we were not able to lower this number, nor change it. Theres no variation, always 188.

It must be the EV-1 then, lets check it... then we found it was installed at 1.5ft from ACU200, and that being so close
and having a lot of places to put it made us look for what else could be wrong and how our network was distributed.

This is why we are opening this post... we mapped the Seatalk network and it just does not seems right.
One more thing I know is that our softwares are all outdated factory standard and updates must be made.

This is what we have listed now on MFD in sequence:

- p70 V2.12 SN0440115
- i70 V1.25 SN0340550
- iTC5 V1.5 SN0240649
- ACU200 V1.6 SN0640309
- ST1-STNG V1.1 SN1200749
- RS130GPS V2.20 SN0441146
- ST1-STNG V1.21 SN0541219
- EV-1 CC V1.1 SN0540855

E95, Radome and AIS were not shown up on the MFD list!


Could you please take a look at the network layout we have down there? I mean, it was placed there by a "technician".
Is this network consistent for me to troubleshoot the rudder drive or any equipments and go for the software update?



Thanks in advance!!
