I just installed a megasquirt 2 extra. I'm pretty sure I have everything hooked up properly. Although after doing the install when I go to start the car I only get a single spark from the coil. I get 12 volts from both sides of the coil, like its suppose to get. Any ideas would help a lot, I have been trying to figure this out for almost a week now.
