Below are some additional forum policies in hopes of all iboats members will follow, Thank you.

1. Please do not reply to old topics or hijack existing topics. Old topics of a technical nature are like a library book, Please do not write in them.

2. Old topics should be considered archives and used for reference only. Please do not reply to them.

3. Do not take over someone elseís topic (aka hijack) with your own question, even if it is similar. If you have a question that has not been covered to your satisfaction in the archives, it is always best to start a new topic of your own.

4. If you have a question for the original poster (OP) and the topic is over 30 days old, send the OP a PM, he may not even visit the forums any longer, or may not notice your question in the old topic.

5. By starting your own topic, you will receive the maximum number of views by forum helpers that may not even notice your question when itís posted at the end of someone elseís topic. And those answers will be specific to your particular issue.

6. Please do not post to topics that have been inactive for more than 3 months unless you are the original poster. We have very active forums and any topic that remains inactive for that long should be considered "dead". It is especially confusing when there is an entirely new question posted to an old topic.

7. Posting at the end of any topic is considered to be hijacking the original posters topic which in turn subjects the topic to be closed if it continues to happen thus not making it fair to the original poster in the future had for some reason he/she needed to return for additional information or provide an update of the problem solved which is always welcomed within a reasonable amount of time frame.

8. Please note that you should see a red banner pop up near the bottom of each inactive topic asking you not to reply to old topics. The Red banner will read: Please note this topic has been inactive for 90 days. For the best results, please start a new topic.

Thank you all in advance for doing your part in helping iboats run a smooth ship.

  • Volvo Penta AQ125

    Hello,

    I have a 1985 Bayliner Capri with a Volvo Penta AQ125 engine. The Trim is not working. When I use the switch, I can hear a clicking coming from the area near the trim motor. Is the electrical component above it a solenoid? I think it may be this part.

    I have been having trouble locating the parts online as well. Any ideas on what I can do to find parts?

    I am going to try to test the motor with a tester and report back.

    No doubt the solenoid is the click Speaking generically it could be worn and not making contact.carefully jump across the solenoid terminals to the motor to see if it runs.If solenoid is bad on some you can open them and flip over the contacts. Usually requires prying the solenoid can open.
    Perhaps there is a main fuse?

      The solenoid is open already and I will try your trick as soon as I can.

        First things first. Your AQ125 is not an outboard, so moving this over to the Mercruiser, OMC, Volvo & other I/O & Inboard Engines & Outdrives forum.

        Now, on to your problem
        The AQ125's do NOT have trim, only a mechanical lift for tilting the drive up for trailering. You also can not open the relays and play with them so forget that.

        When I use the switch, I can hear a clicking coming from the area near the trim motor. Is the electrical component above it a solenoid?
        Assuming you are talking about the black box on the top of the mechanical lift, there are 2 relays and a switch in that box.
        Here is a wireing diagram for the mechanical lift. (click on the thumbnail) and should help you find the problem.

          Thank you for the information. I tested the power going to the switch and there is power going there. I then placed my test light on the motor wires and toggled the switch and it was a no go.

          I think that the problem is the "black box". Is there a way to find this part? I looked and could not find it. The previous owner must have opened the box and the top is no longer there, so I do not see any part numbers. Edit**. I think that this may be the part(s)???? http://www.marinepartseurope.com/en/...-90-18638.aspx. I guess I would just need the relays and the cover?

          I appreciate your help. I am new to boating and hope to learn here.

          Also, I need to have the winterization done. I am in NC, how much longer do you think I have to do this. I was hoping to work on the engine a little more. I just bought an engine manual online and should have it in a few days.

            That dashed line box in the wiring diagram IS the black box. Trust me, this is not an elecronic black box, As I said earlier, it has relays, switches, and connections inside. You MUST understand the diagram to check it out. There is no step by step instructions for troublshooting it. The relays switch up and down by swiching positive and negative wires. There is not an up relay or a down relay. They are both used for both directions.


            I am in NC, how much longer do you think I have to do this. I was hoping to work on the engine a little more.
            I live in WA state, not a clue how long you have. But I will check my crystal ball and see if it differes from your local weather reports if you think it would help.

            Here is the link where you can download a free owners manual that will show you how to winterize. The OEM service manual doesn't help a bit for that.

              What I meant was temperature thresholds. I read that one would want to have the process completed before the temperature is below freezing for more than 24 hours. I do not know if this information was valid or not. We are going through a cold spell here now and it is getting close to 32 degrees, which is the reason I asked.

              I am going to test the black box using your diagram and see what may be wrong. From the link I provided, it looks like I would need to order separate parts, like to top of the box, switch and relays, if needed. Forgive my question formulation, since I do not know much about boats (yet).
