No spark @ plugs , had this thing runnin, shut off fast idle to go for a scoot . It started to stumble, gas , no responce. I lost rpm and died, backfired. refer to XLH service manual , perform resistance checks . Coil is good , control module is good , perform power supply diode test.. good. Perform Coil driver trans check ...good .Verify sensor output in cone . verify grounds . Still no spark ?? I have been over and over and double checked everything ? BUT!! I noticed when I go to first start it I hit the start switch there is momentary spark ONE TIME ! SO, I put my finger on the plug and hit the start switch one time , and got shocked , just ONE TIME . NO MORE SPARK ! ANY IDEAS ?? :small3d026: PS also TACH IS VERY JUMPY TOO !!
