Electric choke issue
Good evening gurus,
Sorry in advance for the long post, but I'm working on an issue that's almost a year in the making.
I've ran into a bit of an electrical issue and I believe it's narrowed down but could use some input. First off, lots of electrical changes. 1967 Barracuda 383 4speed. Now has the American Autowire classic update from back to front and the Mancini orange box electronic ignition. I also added an in dash tach and converted the ammeter to voltmeter. All bench tested fine. After installing everything but the engine bay harness, I hooked up a battery and all was well. Fast forward several long months, and I finished the engine bay. When I went to hook up the new battery, sparks flew.
So I started disconnecting things, starting with the ballast resistor and ignition box harness, and doing continuity tests between the positive and negative cables. I got to the point of disconnecting the electric choke positive cable, at which point there was no more continuity between the battery cables. During my searching, I had found I had continuity between the block and the coil, until after I disconnected the choke positive, now no more coil continuity.
I'm not sure if my electric choke is bad, or if I've wired up the ignition and coil incorrectly. I followed and have triple check all the diagrams and am leaning toward a bad electric choke. When it's disconnected, everything seems to be fine. I can't run the motor yet because the radiator is still out but the starter engages.
Let me know what other info I can provide.
