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.

  • Motor won't start....fuse keeps blowing

    Hi there:I really need some help with my motor. I have a 1997- '90 Johnson Spl. I was getting ready to go fishing when I tried turning the key and noticed the battery was dead. I took a battery out of my cousin's truck(bad idea ) and we used it. The engine started fine the first time and every time after that I would turn the key and immediately the 20 amp fuse would blow. I would greatly appreciate any advice. Thank you

    Did you reverse the battery cables by accident at any time? Better check the rectifier/regulator for shorts...
    Alias "schematic"

      Check all connections. They can be damp by water. Did you connect something to your electrical system just before this happend?Examine the main switch. But if the engine started just fine with the other battery there might be a shortcut in the cables close to the battery. No shortcut when you connetcted the other battery and moved the cables around, but after a while they got in contact again.When your battery was dead, was the fuse ok? You did blow your first fuse the second time you needed it, going home?The fuse is ok if you turn the ignition on but blows when you turn it to starter position, right?/Bear
