    Not looking for help (this time).
    Just wondering how simple it would be to design a logic circuit so that youcar starter is disabled while the engine is running. Why haven't they done this. Am I the only idiot that occasionally (maybe a dozen times in my 70 years) turns the key in my ultra quiet running auto?

    They do make cars like that, but you could always do a
    add on with a vacuum switch to the starter solenoid (NC).

    Vacuum switch, no that is truly clever! Thanks.

    Count one more idiot here. I consider myself to be a careful,
    methodical type. But I still do it, especially when I'm
    distracted - at roughly the same frequency as you.

    But that wouldn't work so well because you can create oil pressure
    before it starts or if for some reason you are having first crank
    starting issues. This is especially true in the winter if your oil
    is thick when cold. If you don't get it right on the first crank, you'll
    need to wait for the pressure to drop..

    hmm, yeah, wire relay to disable the cutout in parallel with the starter relay.
    perhap also use a different measure (tacho or altenator aux output)
     
  7. Most of the cars I have driven have a mechanical interlock in the
    ignition lock. Once you have activated the starter, you must turn the
    key completely to "off" before you can try to start again.
     
  8. The operator's manual very explicitly states that you must not turn
    the key off while the car is moving.

    Also, many cars don't engage the steering lock until you pull the key
    completely out of the lock.

    Another interesting feature is that the steering lock does not engage
    until the steering wheel has been turned a considerable amount off
    center:

    I really don't give a crap what the manual states. It's *DUMB*.
    Most do.
    So you'd better be on a straight road? BTW, that's a dumb idea, too.
    The wheels should be straight when parked (it's hard on the power
    steering pump to leave them at an angle).
     
  10. Maybe they do exist, but I've never seen a car where turning the key to
    'off' also locked the wheel. I've always had to turn 1 click farther
    than 'off' before the wheel locks. I had a Pontiac that was prone to
    stalling, and I never needed to even turn it as far as 'off'. Just shift
    into neutral and crank the engine until it starts.

    BTW, it's *DUMB* (and possibly illegal) to park with your wheels
    straight if you are parked on a hill.

    I was right about you, Fields, you're illiterate.
    What an asshole.Illiterate idiot.
    You really are an asshole. ...everyone knows that, even your butt
    buddy Slowman.

    Allegiance? Fields has *always* been an asshole.

    Yep, butt buddies. The last two posts are Proof positive.

    You don't seem to be able to count anymore. Sad, really.
    You certainly have it all over everyone in the braggart department,
    old man.
    Just the facts, old man.
    Fact, old man.
