I'll preface this post by saying that vehicle wiring is a tough subject for me...
I have a 350 in a FJ62. It has a carb so I have an electric choke.
Recently while working on a few things... I forgot to plug the wire back into the choke, and the wire fell down to the headers... melted... and then shorted out. I didn't wire up this cruiser and the wiring job is shoddy at best. Whatever wire they used coming out of the harness is hot upon the turn of the key, but it wasn't fused in any way. It toasted that wire all the way back to my steering column. Things got so hot, that smoke was coming up from the column. I parked and turned the key off and discovered what the problem was (choke wire). I felt around under the column on the harness to see what sort of damage had occurred and when I grabbed the harness (basically the big plug with all the 10g wires)... my engine started cranking with the key OFF. My ignition now works like this:
Key off-engine cranks and the rig will actually start and RUN with the starter motor still engaged.
Key ACC - Engine stays running with the started NOT engaging anymore.
Key On - Same as above
Key Start - Will engage the starter like normal.
I have now separated all the wiring that I can easily get to, taken apart the ignition switch and put it back together, and this still occurs. I am at a complete loss as to how the ignition is now "wired". It should be noted that whoever wired up the engine swap in the beginning, has one wire soldered to the ignition switch in the "IGN1" or "IGN2" spot, and that runs directly to the starter. This wire experienced no heat. Where the wiring disappears into the firewall, on both ends, appears to not have gotten as hot (but who knows where I can't see.)
If I start the rig like normal, and drive it around everything is fine (now that there is no short) However now i can no longer turn it OFF. Turning back the key, even all the way to take it out does not kill the ignition (however it does run the starter) I have to disconnect the battery.
I don't even understand how this is possible. If somebody who understands the ignition on these rigs could offer some tips... I would greatly appreciate it.
