Any insight on why my wire melted from coil to dist.? Heres the background so blew the motor in my 64 f250 (292 y block) tracked down new motor came from 58 or 59 ford car possibly fairlane or country squire swapped my parts over to make it mountable in the truck (oil pan and pickup tube timing cover and water pump exhaust manifolds alternator brackets((gm one wire)) intake manifold) using all my parts on the new motor like coil and starter and solenoid new cap rotor plugs wires after everything was hooked up I dropped in a battery and went to crank it after about 10 seconds of cranking I noticed some smoke got out to check and noticed I'd melted a wire so I'm wondering does anyone have any idea what would have caused it? From my searching there's no real difference in the distributors and all my wiring is exactly the same as when I pulled the old motor hell most of the parts are the same ones could it be a bad ground from the block? I still have my old distributor from the 64 block but would like to figure out any issue before swapping it in and melting it too. Thanks in advance -Mike.
