Replacing ST4000 control head with ST6002 control head

My old ST4000 wheel pilot went wrong last week.
When I turn on AUTO, suddenly the steering turns to right and it does'nt stop.

My friend advised me to replace my old ST4000 control head with new ST6002 control head. It seems the simple and the lowest costed way for me to renew.

But I'm afraid if old wires cannot connect to new ST6002 head, because many wires gather into control head unlikly as the new product, as shown by PDF below.

Please let me know if I can replace ST4000 control head with ST6002 control head without changing old wires.
Or should I buy new wires together and change the end of wires to fit compass and
wheel drive ?

The compass and wheel drive seem going well.

Thank you.

You can not replace a ST4000 control unit with a ST6002 control head, the reason is the ST4000 is a control unit and is a control head and course computer all in one.  The ST6002 is just a control head and you would also need a X5 course computer with the ST6002. You will be able to use the drive and the compass with these two items. 

Just to troubleshoot the issue, was the ST4000 showing good heading when it just went hardover?  It seems the system didn't have heading, hence the reaction.  I would first recommend re-calibrating the compass in the system.

 

 

Thank you Mr.Rhino Horn.

I checked ST4000 wire resistance to the compass and set re-calbrating , this weekend.

Only wire resistance between Screen and Red that should show 0 Orms, showed a little resistance 0.4-1.4 M.Ohms. (It was moving ,didn't fix) But other resistances were in normal range.

Then I went short sailing. After checking the compass showing correct, and when I turned on to AUTO, the trouble that made steering turn suddenly, was disappeared.  I can't understand why the trouble was solved.  I wonder if the trouble may come again.

The result of re-calibrating, deviation was bad. It showed 16 degree . But difference between ship compass and ST4000 compass was a little, defferences were max. 5 degree and min. 0 degree. I don't feel defficulty to sail with ST4000 compass.

Please let me know if the fluxgate compass was the reason of this trouble , or the reason of 16 degree deviation , and what to do if any .

Thank you

When the autopilot reacts by going hard over it usually is searching for a heading.  So, the compass could be the issue.  That is an unacceptable deviation, 16 degrees, when a deviation is that high it usually points toward the compass being affected by outside interference.  Check the area the compass is located for anything new that is electronic or has ferrous metal within 3 feet of the compass's location.

Thank you Mr.Rhino Horn.

I'll check somthing electronics or ferrous metal near the ST4000 compass.

Although boat compass showed nearly the same hedding, these 2 compasses might be affected by somthing such a material.

I'll check hedding by handy bearing compass free from deviation.

But can I doubt high deviation may be caused by a fatal trouble in ST4000 compass ?

Thank you.

Replacement fluxgate compass part number for the ST4000 is M81190.

Thank you Mr.Rhino Horn . 

I'll replace fluxgate compass near future.
