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.

  • No Spark 99 Suzuki DT200 EFI

    Help. motor ran fine last time ran. Now no spark on any cylinder. I have twins so I swaped the coil banks with no change. Please give me any troubleshooting advice for this condition. The temp, check engine etc cycles when key is turned on and pump runs and warning buzzer sounds just like my running motor so power is getting to the motor when key is turned on. Thanks Jeff

    Did you check the kill switch?

      Only one switch for both motors and one runs so I assume it is not the problem. Thanks Jeff

        never assume anything.
        this engine has a fairly complex micro-processor.
        however its like almost anyother ADI ign system.
        test out put from the stator charge coils, test trigger coils,test crankposition sensor output then test CDI output.
        looks complex but its really not.
        but electronics failures on that engine is very very rare. usually its someplace other than stators and CDI units.
        no tech questions by PM, they wont get answered.
        you have to be trusted by the people that you lie to .

          Thank You for your quick response. I am waiting for new manual as my selcor manual does not match my engine in wiring diagrams. I do have twins if you can suggest other part swapping while I wait. Also I heard there is a test procedure for eliminating any control problem that involves unpluggging the harness and starting by jumping some wires. If so please let me know the procedure if it exist it sounded good to be able to eliminate any componets outside of the engine cowl. Thanks Again Jeff

            Re: No Spark 99 Suzuki DT200 EFI

            Finally got correct manual. This 98efi Dt200 does not have a seperate cdi unit The electronic contol unit incorporates the cdi function. I tested crank sensor, Stop switch and key circuit. All tested good. Checked ignition charging coil and speed sensor with good test results as well. Checked the power source regulator and even swapped the electronic control with twin motor. It runs the other motor but after reconnecting new module still same results on first motor. NO Spark on any cylinder. Really making me pull my hair any ideas greatly appreciated Thanks Jeff

                Thanks for reply. I did in fact find the nuetral switch to be the fault. It seems Suzuki made a system which kills the spark instead of the starter like most everyone else. A local dealer just told me to think backwards for suzuki as they are not of American design.
