Question about Simrad AC42 Course Computer w/Simkit-1

Open Question

I have just installed an AC 42 Simrad controlling a b&g Ram. Rudder works fine but the drive is always engaged, including on power on. The engage solenoid on the ram draws maybe 1.5amp, way less

I have checked the voltage of the drive engage terminals (connected) which is constant at 12v, even on start up and on standby.

    I have a potential answer from the Simrad team. It appears that the switching of the clutch is on the negative and I likely have a leak / ground on negative. So fitting an intermediate relay is the answer. Great technical service team. Eddy

SOURCE: Problem: Autopilot does not

jimtippettau:
Which drive are you using with the AP24, is it just a hydraulic pump on a powerboat, like our RPU80, or is it a hydraulic linear drive (like our HLD-2000) or draglink drive (like our DD-15) on a sailboat?

SOURCE: simrad ac10 current overload

I think the AC10 is maxed out at 15 amps while the AC42 goes to 30 amps. Iknow the AC10 is better with solenoid systems and the AC42 for reversing motors.

Remove the battery, and connect the AC power. Then, try to start it.

Disconnect the AC power, and remove the "new" disk-drive.
Then, connect the AC power, and try to start it.

Disconnect the AC power. Remove the "new" RAM, and put the "old" RAM back in.
Then, connect the AC power, and try to start it.

If it does start, add the "new" disk-drive, and try again.

If it does start, add the "new" RAM, and try again.

MY SIMRAD AUTO pilot is telling me rudder error what is the problem is it the linear feed back cylinder


Has it ever worked?
What has changed?
Is it the a "pole/linear" or a "rotary" FB unit?
Out of the 5 basic parts of the AP system, the RFB is the most replaced due to the environment (Splash, heat, vibration, mech movemnet).

"Rudder feedback error"
does not see the RFB at all.
check the connections in the J-box first.
you should be able to manually turn your wheel and see the RFB indicator change on the control head.

"rudder responce error"
does not see the RFB move when the AP is given a command.
then check physical connections.
could be loose, could be backward?

seems to be a problem with the rudder feedback sensor first check if rudder sensor is not mechanically disconnected,if not try to do de setup procedure,reset the unit to factory condition,try to set rudder limits,if this is not working ,check with other feedback unit.

I have 1994 Carver with Simrad AP which I would like to update as economically as possible. How do I do that?


The original hydraulic pump, rudder reference and compass should work with the newer systems so you can look into buying a new course computer and display in seperate pieces. You may find however that new ssytems are packaged in such a way that it will be the same price to just buy a complete new system. Whatever you decide, it is worth a phone call direct to Simrad to be sure that everything is compatible before you spend any money.

Autopilot shows "no rudref"


The rudder sensor works like a light dimmer, so you get 5V and ground on the outside two connections and a varying voltage between about 1 and 4 volts depending on rudder position

Simrad ac10 current overload


Normally this is the electric motor causing this problem. Just went on a call and had the same thing. Checked voltage coming from the AC unit to the motor and had 12 vdc then put a new one in it's place and it solved the problem. You don't have to change the pump portion, just change the motor itself. Indeed you will have fluid leaking but many times it's better than plumbing in a new pump.

AP35 Autopilot


Yep, if rudder calibration values are OK, then there is a real problem with calibration, it can be a mechanical problem or a faulty rudder feedback unit. Follow procedure at page 93 of user manual :
AP35 Autopilot Instruction Manualto troubleshoot the error, if you cannot get rid of the error message you may have to replace the rudder feedback unit or to have the unit inspected by a technician.
