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

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.

Wouldn't expect ant codes with this issue. If you have a volt meter check for 12v on the small terminal of the solenoid. 12V should appear when the key is turned to the start position. If 12V dose not appear when key is turned to start your switch circuit has a problem. If you have no volt meter you can do this test by turning the key to the run position. Then tap the small terminal of the solenoid with a wire that is connected to 12Vs. This can be from battery or the hot terminal on the solenoid. If the starter dose not engage the solenoid part of the starter is not working. You got a bad starter take it back for a replacement. If the starter engages your switch circuit has a problem. & good luck with that.

No start...2000 Wrangler 4.0liter, automatic.

To me it sounds like you have weak battery. Hook up a meter and check voltage. should be over 12v, then turn key on. should maintain 12v. then crank. If the voltage goes below 11v cranking the battery is bad. Be sure to test the battery. Not the cables. Then tst the cables. You may have good voltage just touching the battery and you may have low voltage touching the terminals which would indicate a dirty connections.

Also check to see if there is power in the start wire form the ignition switch, the wire is a white wire with pink stripe, most likely not a common problem, but still something that could go wrong. this wire will feed the starter relay under the hood...

When I turn my car off a little light on my amplifier stays on! It looks like it's a lightning bolt?! I want to know if it is bad that that light stays on when I turn my truck off?

Hello rlpate1, Most likely whoever installed the amp used speaker level inputs and the "smart engage" turn on feature instead of a remote turn-on wire from the head unit. Just like your dome lights, the amp light should go out after a while, exactly how long depending on MTX's internal setting. I wouldn't worry about it as long as it isn't discharging the battery and causing your truck to not start. However, it's possible that the 12V turn-on terminal is being used and the head unit or whatever it is wired to is supplying a constant turn-on voltage even with your truck turned off. In this case, you definitely need to fix it. Otherwise, it will eventually discharge the battery and you will not be able to start the truck. Check the switch marked "smart engage" to see if it is on or off. If it is on, you're probably OK. If not, have your installer check it out. Hope this helps.

Starter wont engage

The problem is either the starter solinoid (located on fender near battery) or you are not getting power to the "s" terminal on the starter solinoid from the ignition switch. If you follow the positive battery cable from the battery you'll follow it to the solinoid. Remove the small wire from the terminal marked "s" on the solinoid and using a screwdriver jump from "s" terminal (not the wire) to where positive battery cable connects to solinoid. (with battery connected). If starter doesn't do anything the solinoid is bad. If starter cranks then you are not getting voltage from ignition switch through "s" terminal wire.

Truck will not even crank over to start

Test for voltage at small wires on starter solenoid, by the stud on the starter, when someone trying to start. You should have power to it, or one of them, when key is cycled to start position, and none when you let go. If power there, my guess is your solenoid. May have to take starter off & bench test it. If no power to there, locate that relay you hear clicking,and check it, for constant power source going in, and one or more coming out when key cycled, which should be power source for wire at solenoid on starter.

Amp protection light comes on when raising volume...

It sounds like you either have too low of an ohm load or the voltage is dropping at the amplifier's power terminal.

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.

If the voltage remains near or above 12v, disconnect one speaker and see if it shuts down. If it doesn't, disconnect that speaker and connect the other speaker. If it only shuts down with both speakers connected and the voltage is staying above 12v, the ohm load is probably too low and you'll need to rewire the speakers.
