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 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.

    Re: power packs

    I would start checking if the kill wire possibly gets ground somewhere, if you miss spark at all - try to disconnect at pack, and see if you get spark. Next step would be to check and clean all ground connection - both from stator and power pack. Also try to disconnect the amphenol connectors and clean - i had that problem myselves. Reply again then.

          Re: power packs

          Texas_Angler_2002.... This "No Spark" condition can be caused by a failing ignition switch which creates a weak resitance between the "M" terminals of the switch, in effect shorting out the P/Pack(s). The shorting of those "M" terminals is the normal condition when the key is in the "Off" position. To check the switch to see if that's your problem, remove the black wire that has a yellow stripe (black/yellow) from the back of the ignition switch. If you now have ignition, the ignition switch is faulty and will require replacing.

            Re: power packs

            Ditto JoeIf you still have no spark, disconnect the black/yellow wires from the packs and try again. This will eliminate a possible wiring problem from engine to controls. If it starts, you may need to choke it to shut it down....good luck

              Re: power packs

              I have been following this post and have a similar problem.If the black and yellow wire is separated from the power pack and there is now spark, what is causing the no spark condition?

                Re: power packs

                don't know what your circumstance is, but if you have spark when black/yellow wires are disconnected, it can mean one of two things:>the kill switch is activated(lanyard), or the circuit is grounded (bad ignition switch or wiring to it)>the isolation diode in one or both packs is shorted.(this applies if the no spark occurs when packs are connected together, and kill wire is disconnected)Also try disconnecting the rectifier totally. If spark returns, check rectifier...

                  Re: power packs

                  I received a mild shock while turning the key switch to the starting position. Wiring to the key switch appears to be in good condition. The key switch is new. Any suggestions and help is greatly appreciated.

                        Howdy Flboater.I would think that you are recieving the shock from the tall tower on the back of the key switch. Originally there was a plastic insulator wrapped around the switch to prevent this, the tall tower has the charge coil voltage on it, this is approx. 250 volts ,and can jump a pretty good distance.Just a thought

                          Re: power packs

                          There was a plastic type of coating on the back side of the original switch, around the terminals. What would be an appropriate coating for this on a new switch?
