The #4cylinder measured between red 12v and middle ground shows no power until engine is cranked. 12v to oposite end connector shows power with key on accessories position and drops very low when engine is cranked. flashes to 4-6 volts for a second. The battery is a little low.
OK this is weird. The other two cylinders show power from red 12v pin to center ground pin. They both show power from red 12v pin to the one on the opposite end with the key in the accessory position but the difference is that when you crank the engine the power does not drop like I saw in the cylinder 4 plug.
Not sure where to go from here.
