I tried to get my new engine going for a couple hours tonight and it just cranks, no fire.
Got fuel to the carbs, but no spark at the plugs (IMG:style_emoticons/default/sad.gif) Checked the coil and I get 12V off each side to ground, is this correct? What is next in the diagnosis...what else can I check? |

Still coming up with nothing...
I don't have a test lamp, so I just used a multimeter expecting to see a voltage drop. When cranking, I get the same thing off both sides of the coil...the voltage drops from ~12V to ~10.5V and holds there. I pulled the coil wire off the distributor and couldn't see a spark while cranking, but I'm not sure if I should "see" it for sure. Points are opening and closing and the ground braid looks fine..both the distributor and coil look new, but who knows... Any ideas? |
