Help Tip: If you have a question that has not been answered to your satisfaction in the archives, it is always best to start a new thread of your own. By starting your own thread, you will receive the maximum number of views by forum members.

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

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

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

3. Do not take over someone elseís thread (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 thread of your own.

4. If you have a question for the original poster (OP) and the thread 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 thread.

5. By starting your own thread, 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 thread. And those answers will be specific to your particular issue.

6. Please do not post to threads that have been inactive for more than 3 months unless you are the original poster. We have very active forums and any thread 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 thread.

7. Posting at the end of any thread is considered to be hijacking the original posters thread which in turn subjects the thread 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 thread asking you not to reply to old threads. The Red banner will read: Please note this thread has been inactive for 90 days. For the best results, please start a new thread.

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

  • No Power on Ignition Switch Merc 260 1984

    1984 Mercruiser 260 5.7L S/N 6846787
    I had never had problem before and last week end I tried to start my engine with no luck.
    When I turn the key, nothing happens; No Click on the starter, the guages does not have power doesn't move.
    I checked the Ighition Switch Fuse and it is not blowed. I have no voltage at the Batt Wire on the Ighition Switch.
    My Quick Silver Control is on Neutral Position (knob pressed).
    I need some help with my problem.
    Thanks

            When you test the circuit breaker with the test light or a volt meter, make sure you check both terminals. It wouldn't be the first breaker to fail for no reason in the marine environment on a hot engine that probably gets wet with condensation.
            Might also check to see if you have a 15 or 20A fuse under the dash near the ignition switch in the red/purple wire.

              I checked the 20A fuse under the dash near the ignition switch and it's OK
              The connector from the 12V panel that supplies electricity to the fuse was defective.
              I replaced it and all is working now.
              Thank You All for your help.
