this is for the q-jet carb.

Does anyone know what the voltage is supposed to read when the engine is cold for the electronic choke. at cold my voltage on it reads about 12 volts..

does 0 volts mean the choke should close, and 12 volts mean the choke should be open?

thanks for your help again

 

The choke is supposed to have 12volts at all times.

Unless the key is off.

 

hmmm
Then what else would make the choke stay open all the time? after i rebuilt it, it decided to stay open, and now it only idle's correctly when the car is warmed up.

thanks again

 

The stat is probably not assembled correctly, such that it's not closing the choke. Check how it's put together.

The electric power makes the choke open; it should spring shut all by itself from the tension in the stat. It's a bi-metal, made of 2 metals with very different thermal expansion rates; it curls and uncurls as the temp changes. The electric power heats it.

There will not be 12V on it unless the car is running and the alternator is charging. It is designed so that if you turn the key on and let it sit, the choke will remain cold. It is interlocked with the alternator circuit in such a way that the "Choke" light on the dash is actually the "Alternator" light.

 

would this stat thing also be creating my bog? and when i put my carb back together i probabbly just didn't put the stat back together correctly?

 

RB83L69, if i have an non stock alternator (i dont know where and from what it's from) is it normal that my "choke light" in the gauges does not work?
Will the choke still works??(i think so, the RPM is high in cold start, get warm and i can pop gas so i get my 800 rpm)
Anyway i run very rich, may it be choke related?

(i have not bought my rocherster book alredy, but soon...)

 

No, that is not normal; it should work regardless. The bulb is probably burned out. And if the bulb is burned out, the alternator may not be working as well as it should.

Hard to say about your rich problem... a choke that sticks on will cause that.

 

Ya, RB83L69 is problably right. If camaros are like the monte carlos there is a oil presure switch that conects to the choke wire. What it does is not let power get to the choke unless their is oil presure.

I made the mistake because I have my choke hooked up the ignition so if the key is on theres power on the choke.
