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? |

I'm still waiting for some help to arrive to help with cranking, but in the meantime, I'm still a little confused why I'm getting 12V off both the + AND - side of the coil when the key is in the ON position, shouldn't I only get 12V off the + side?

QUOTE(biosurfer1 @ Apr 28 2009, 10:38 PM)  ...shouldn't I only get 12V off the + side? The short version is you'll only see ground on the - side when the points are closed. If you turn the engine by hand and you -never- see ground at the 12V side, find out why your points are not closing. You get spark -only- when the points open. |
