What would cause 12v on one side of coil plugs and at most maybe 3 to 4v on the other side? That's with ignition on and kill switch to run and while I'm not turning the bike over. When I crank it the low number side goes up to around 5 or 6v?..... I don't understand I've tried And tested everything except changed ECU... I've changed the pulse sensor and still nothing
