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? |

If you have the stock system, remove the distributor cap.
Connect one end of a test lamp on the negative (point side) of the coil and the other to ground. Crank the engine and if you get a pulsing light, the points and coil are working. If the light stays ON or stays OFF during cranking, then the problem is not the coil and you need to look elsewhere- such as the points and condenser. Put the test lamp across the positive and the negative terminals of the coil. Have somebody crank the engine over, If it pulses, then this means there is 12 v to the + and - terminals, and the points and condenser are working. Look at the points, if they spark when opening and closing, you probably have a bad condenser. Put the cap back on. If you still have no spark, then either the coil is bad or one or more of the coil wire and/or spark plug wires are shot. Hope this helps. |
