I've been reading about the ST4000 and repairs - can CaptainDan99 repair these? Some of the posts suggest you do. I just shared an email with Raymarine and received the disappointing "no support no parts" response. I had the unit re-wired, it's getting plenty of power.
Here is their response. Any advice is appreciated, and I wish you a happy Thanksgiving from sunny St. Petersburg.
I'm sorry the ST4000 is a retired product which is no longer supported by Raymarine simply because we no longer have parts to repair them. The low Batt error message is either from a low input voltage or a main PCB failure. The fix would be to replace the PCB , but again we no longer have any parts. The replacement autopilot is the X5 wheelpilot or X 5 tiller pilot.

I am submitting a post from SAILNET which describes my problem.I have read the posts myself, and the reports are that this unit had chronic problems. I bought the boat 3 years ago, I can get the serial number easily enough, but the problem is pretty obvious since it is being experienced by so many others. The batteries on the boat are in fine condition. I had the unit re-wired a short time ago. No change in the problem.
Here is the post I copied.
I got the "low battery" reading as well. I had the Raymarine repair guy on my boat. He took all sorts of readings checked my connections and called Raymarine. They said the unit has issues and could be sent in for repair but they could not guarentee they still even had parts. They offered a reconditioned one or a new model at a discount. I'm waiting for prices.
This unit and issue has come up on a nimber of blogs I've read. Ths consensus is to replace it. The new unit comes in two parts and is supposed to be better built since they did not try to cram all the necessary stuff into that 1 small box.
What are you willing to do, or what can you do about these units. It is disappointing to read to many problems, and doesn't really engender thoughts toward purchasing another one, and the unit is only about 9 years old - no parts?
