    This is just a quick simple solution to that car won't shut off issue...
    I was working on a O/T Gm powered that had this very issue... Realized I only had one Diode left for said fix..
    I still had the store bought package when radio shack was still brick an mortar, Searched the part # , Sure enough it was still available
    Soo I thought I'd shoot you guy's needing help in this department the fix, splice/solder one of these in the keyed wire going to the alternator , Slide a piece of heat shrink on before, Done! KIMG7301.JPG KIMG7300.JPG

    Or....you could hook that wire to the acc side of the ign switch, does the same thing.

    I like to go to the drive-in.

    If I wired my ignition like that, I might not get it started when it is time to leave.

    Diodes are cheap, and easy to install, and are much better than getting yelled at by the wife.

    Any electronics supplier will sell you gobs of 1N4004 diodes for anywhere from a few cents to a half a buck apiece, depending on brand, quantity desired, etc.

    If your car has a acc terminal on the switch just wire the alternator to it.
