Here's what I've got: '62 Ranchero, with a Duraspark/HEI ignition and the original 2-pole starter relay ("S" and "I" wires coming off the relay). I fed the ignition by replacing all but 1" of the original resistor wire behind the dash with regular wire, the only bit of resistor wire left is right at the firewall plug.
I've got two problems that I'm trying to figure out...
1. Occasionally, (like once a week or so) my Ranchero's starter relay will just click when I hit the key to start. Usually the second try it'll spin over and start just fine like nothing's wrong, sometimes it'll do it twice (just click). Battery is fine, I've cleaned all the cables and contacts. Replaced the starter relay a couple of months ago, but no difference.
2. When it does just go 'click', if you don't let off the key immediately, you get a lot of current coming back through the ignition feed wire (from the switch to the ignition coil). I know this because it burned the insulation off of the tiny bit of original resistor wire by the firewall plug (lots of smoke that morning) Since then, I've disconnected the wire from the "I" terminal on the starter relay, thinking that it was somehow back-feeding.
Any ideas what to look at next, and why it'd try to burn up wires?
