Automobile starter lockout

Not looking for help (this time). =20
Just wondering how simple it would be to design a logic circuit so that you=
 car starter is disabled while the engine is running.  Why haven't they don=
e this.  Am I the only idiot that occasionally (maybe a dozen times in my 7=
0 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). Jamie.

Vacuum switch, no that is truly clever! Thanks. Ivan Vegvary
It happens that Ivan Vegvary formulated :

Just buy an Australian made Commodore (GMs 6 cylynder). lol -- John G

Or a relay driven from a signal from the oil pressure lamp. If you tap the circuit at the lamp, it will provide a 'high' to drive a suitable transistor or fet controlling the relay when the motor is running

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.

Good point. It is such a simple thing. My BMW MC had a starter interlock that wouldn't allow it to start unless the engine wasn't turning and it wasn't in gear.

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.. Jamie

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) -- &#9858;&#9859; 100% natural --- news://freenews.netfront.net/ - complaints: news@netfront.net ---

Well I guess I have to admit it is the use I have with a diesel motor. The motor is running for several seconds before the pressure is high enough to turn off the lamp in any weather ( Of course here in God's country we don't get freezing etc ) :-) .
