Hello i have a problem because i had backfire on my ski i checked a few things! First i checked compression thats ok. Checked injectors they are also ok. Last one checked for spark thats seems to be ok. I look at the battery and this one is compleet dead so i think the battery causes backfire!! Now its comming when i hit for the last time the startbutton to look for spark nothing happend compleet dead. When i put the lanyard on the dess only dashboard light come on, no beep no nothing??? I just hear a click from a little square relay at gastank side!! Can anyone help me with this problem? Thank you gr Henk
