    Alex It sounds like the coil to me. When the coil gets warm / hot it must be a open circuit? I would replace the coil and plugs.
    Good luck

    I agree, but I'm not too experienced in this. I know the coil is a dual fire and the same unit alternately fires both plugs on the power stroke.
    If that coil were failing when hot (like they tend to do), it makes sense the engine would stop running, but this doesn't necessarily explain the front plug being fouled.
    I would change the spark plugs first because they are cheap. Then the coil. I looked in the manual and it says to diagnose coil problems by eliminating everything else....hmmmmmm.

    If the front plug was not firing before it shut off. It would be wet? Also if it was only the plug. Why would it not try and start until it cooled down.

    SKOGDOG are you sure that the coil is dual fire?

    Hi Dean,

    hm, an update is not possible, cause I have no computer connector cable outside at the box, what would make trouble when it comes to water proof. Don´t worry, I have the same function in my G-Box ( http://www.elektronikbox.de/ebox_g_uk.html ) and in my D-Box implemented and right now there was no response from any customer that he had experienced this problem and I sell about 15 - 20 times more of my other electronic boxes. I have switched my own EHC back to the "Auto" mode after a few days running with the "traditional" mode, cause I feel it much more comfortable to start the bike immediately after turning the key (or switching on the ignition via smartphone in my bike.) .

    However, just contact me at info@elektronikbox.de if you feel a bit worry and we´ll find a solution :)

    All the best!
    Axel

    Hi Todd and Rick,

    Thanks for the suggestions. I think you are right. I just ordered 2 spark plugs from Amazon and will order a coil from Bikehouse Sweden when the change was not successful. Then everything should be fine. Let´s see. I´ll keep you inform when my bike is back on the road for a longer time than 2 minutes :)

    All the best!

    Hi,

    Just an update: I got the spark plugs today and have put it in. Everything is fine again. Riding the bike is already a bit "boaring". Nothing is shaking and makes (additional) noise. The new ignition is fantastic (except that I get a wrong signal for the rpm indicator and my led´s in the speedo play "disco flashlight" when the engine rpm is slow but who to fu.. need rpm indicator. I´ll take care for it at the next wintertime) It´s unbelieavable what spark plugs can do. It´s difficult for me to understand why they work fine when cold and fail when hot. However it works :) and I can do some miles within this weekend.

    All the best and a nice weekend!

    Thanks for the update.
    I am glad to hear it was only plugs.

    Hi,

    First I want to thank you all for your great and helpful posts in this forum. You all helped me with the right suggestions to develope my EHC modules almost 3 years ago. Now there are already some hundred of my EHC´s implemented in great bikes. I never expected this quantity when I started the development. Thanks a lot for your trust and your help! (Thanks also to Rollo from Hamburg for his unbelievable patience, when he had used one of my first EHC´s in his bike, that died 2 1/2 years ago in a rain shower in Spain, far away from any village... )

    However, It´s already far too cold to ride my Ridgeback here in Germany (Ok, I´m not a hero...). My bikes are in the garage and connected to battery chargers and I just make some software updates in my other electronic boxes. I also would like to make a few minor software updates in the EHC devices within the winter time and want to ask, what software option could be on your wish list? One update might be the possibility to switch off the head light when pressing the light button longer than 2 seconds. Any suggestions or other ideas ? Is there anything what you don´t like on your existing EHC and what could be solved with a software update for future EHC´s ?

    Al the best!
    Axel

    How about if you hold start and horn together for 3 seconds, ludicrous mode kicks in.

    To be able to turn off the headlamp would be nice. How about the ability to update software?

    Hi Kobi,

    Sorry, a software update is not possible. I decided to make the boxes as waterproof as possible before and every additional connector to the "rest of the world" like a pc makes any kind trouble (You see what happen in the old EHC...). However, the older EHC work also w/o trouble if they don´t have this function implemented. I hope it would be ok.

    All the best!

    How about headlight off when transmission is in neutral? Is this a possibility?

    Hi Joose3,

    Hm, the neutral switch just passes the EHC but is not connected internal to the microcontroller. It will need a bit hardware modification to check it. I´ll keep it in mind. However I´m also a bit afraid what happen if you wait at night time in front of a red traffic light and the gearbox is in "neutral" position. Let´s keep it in mind as well...

    All the best!

    Oh, yeah! I see your point. It might not be such a good idea.

    Isn't there a sensor in the speedo/tach that senses the ambient light? Can this be put in series with the neutral switch to turn off the headlight? The ambient light sensor probably does not go into the EHC either??? Just a thought.

    Hi Joose3,

    Yes, there is a sensor in the speedo/tach.

    By the way, I just make a something similar product for a catalogue distributor here in Europe ( www.louis-moto.co.uk ) It´s a head light switch what toggle between low beam and daytime light, depending of the ambience brightness. Here is the schema:

    Daytime_Light.png

    The first prototypes are ready and I´ll bring it on the way to them next week. Just send me a message to info@elektronikbox.de with your contact details if you would like to try one prototype and I can put one device in an envelope and bring it on the way to you.

    All the best!
