I have been trying to trace down a short for a couple of weeks as part of my engine swap project (289 auto). I thought I found the problem last night in a couple of bare wires in th ewiring harness along the power steering pump area and one was almost completely broken in half. Fixed those, hooked up the wires to the starter relay, and the engine actually ran!! Except when I went to turn the key off nothing happened. It kept running. So I got out and pushed shut the choke and it stopped. Went upstairs to brag to SWMBO about my electrical prowess, ::came back down 10 minutes later in time to watch the top of the coil break apart and foamy gunk come spilling out. The key had been off all this time. I pulled the positive battery cable off, but now what is the problem? Do I have a bad ignition switch? Any thoughts from someone more electronically inclined than I obviously am?
