66 Dart/74 la 318 starter issue
Turns out it was any one of a number of things, or a combination. A previous owner spliced two wires going into the bulkhead connector, badly, (I’m not sure why they’re spliced in the first place), so that was a tenuous connection, the wire from the solenoid to the starter showed continuity, but had an old butt connection in the middle, so I replaced that wire, and I think the original wire from the bulkhead to the relay was just hanging down and I think shorting against the firewall.
Either way, it’s running now. I have some wiring issues to chase down and clean up, and I have to adjust the throttle cable and timing. (Throttle cable is coming up a bit short and not letting it drop all the way to idle. 2 bbl throttle bracket to a 4 bbl carb, but I had to use it for the style of kickdown linkage I’ve got. Might have to fashion a small extension for the throttle.
But it runs, and has way more bark than my old, tired 318. This one has Performer intake, edelbrock 600cfm carb, 360 heads, I think a .030 overbore and a small cam.
