Heading to the garage now to start the install and my main, unresolved-in-my-brain question is if i need to hook up the vacuum line that is on my current stock distributor, on the 123. |

One thing that you mentioned to me, Ed was to disconnect everything from the coil, run a line direct from + side of the battery to the + side of the coil and then connect the red from the 123 to the + at the coil and the black from the 123 to - at the coil. Connect the blue wire from 123 to ground. This circumvents the primary circuit and if it fires in this configuration, indicates too much resistance in the primary. It's on the list - didn't do it originally as I always felt I was "this close" by doing the standard setup. I'm confused! That's how the 123 is wired per their instructions. I'm thinking, wired up this way and rotation of shaft SHOULD make sparks. Ed's response brings up "the old car syndrome" and he's right. What is the condition for the main feeds and grounds? I'll add an "instant" ground with the negative side of a pair of jumper cables to check if that helps. I'm planning on a new coil with correct internal resistance at install with mine. Have you changed the coil? |
