raymarine ST 4000+ conversion to EV 100
« on: September 09, 2019, 12:56:00 PM »

The belt on my ST4000+ broke.  After replacing it, I could not get the wheel to turn properly when it was engaged.  I bought a replacement wheel portion, which turned out to be the EV100 wheel.  I installed it using the old cable as it would be a nightmare to replace the cable.  Now, it will not hold a course.  It will start with making small adjustments and then they keep getting larger and larger until I was weaving like a drunk.  I tried adjusting the gain to no avail.  I re-swung the compass and adjusted the heading on the autopilot to match the boat compass.  Now it holds until I engage the autopilot, whereupon it changes.  Any suggestions?
Thanks,
Dan

Dan,
It looks like there isnít anyone here who can help. Iíve found the Raymarine forums and FAQs to be helpful. There are Raymarine moderators who can and will answer most well framed questions.

Good luck... I too am having trouble with my autopilot (SPX-5) and need to post a question or two on the Raymarine forum.

Hi Dan,
Well I'd *like* to help. I just don't understand why the wheel wouldn't turn properly after replacing the drive belt, especially if everything was working before and it was the correct replacement belt. Buying a new wheel seems a little drastic, even more so if it's not an ST4000+ wheel/drive (which you can still get - see  https://www.hodgesmarine.com/RAYMARINE-ST-4000-WHEEL-DRIVE-E12093-p/raye12093.htm.) I seriously doubt the drive for a EV100 is compatible with the ST4000+ "head."

It seems coincidental to a belt change, but is there a possibility your ST4000+ head has gone belly up? I had a SeaTalk failure in mine back in 2013, and at the time Raymarine had a flat rate repair policy. My 4000+ has been a rock ever since. (He says knocking on wood.)

I'd agree with Dave. The Raymarine forum is probably the best place to start. You might have to wait a day or so for the answer/suggestion, but they've helped me out a lot.
