Hello.
Seeking advice regarding a few issues on my 1981 corvette.
--A PO has locked the choke in open position using a plastic strip.I am sure he had a reason for doing this,What is the logical way to troubleshot this issue?
--There is a disconnected wire in front of the carb.Black wire with a green plug.Anyone have any idea where it is supposed to go.
--There is also an disconnected two-pin sensor in the passenger side cyl.head.Right above the starter.The plug is hanging beside it.What is this sensor for?
Thank you.
Just to clearify.
The green plug is not supposed to be plugged in during normal opperation?
If I connect the two leads(bypassing the sensor)the electrical fan should start running?
If the lead to the choke has 12V when the car is running the electrical choke is bad?
Thank you.

green plug hangs loose. used for tuning testing.
dwell meter set on 6cyl
yes, the lead jumped should spin fan
no, 12v to choke only means the power is getting there.
the coil could be bad, or out of adjust.
need to drill out rivets and turn
By-passing the auxiliary cooling fan and having it running all the time is not wise. Or at least I would not do it that way.
IF anything I did other than get that circuit repaired correctly...I would wire it up so when the A/C was turned on..that fan would come on.
Also before you go and drill otu rivets and mess with your choke adjustment. I would check to see if it is even working first.

I wasnt planning on having the fan run all the time.The bypass is just to test if the fan is working at all.Btw.the AC doesnt work.Dont need it either.Look were I am living.
The choke thing is annoying though.Have to fix that.

I was just mentioning it.
I have no clue on where you live due to your Public Profile is not showing where you live.
And as a mater of fact. When the windshield defroster is turned on...your A/C comes on so that you are not blowing super heated air on the windshield and causes it to crack. GM blends some cool air from the A/C system with the heated air from the heater core.
Cars that do not have A/C...it is different....because outside cold air is blended with the heated air from the heater core.
I can tell you that hot air hitting a windshield that has ice on it can shock the glass.

Now it shows where I am from.The thing is that I use this car only on nice summer days.And on a nice summer day around here the temp.seldom creeps above 80 deg.
Seems like the heating element is broken.Removed the the choke and hooked it up to an external 12 V source.No heat and no movement to the spring.I need a new choke,but cant find the part number online.Wonder if anybody can see which carb I have.There is no tab on it as far as I can see.RA lists two chokes for a -81 vette.One for carb M4ME,one for E4ME.The old one has a sticker with 70450 one it underneat the sticker printed GM17059182.Cant find these numbers in the crossref. charts.

Your carb is an E4ME carb.
Not sure why they list one for an M4ME as no 81 vette had one.

You can use any electric choke for a Q-Jet. Since Summit Racing ships to Norway, you can use Summit part number EDL-1932. Make sure you do not have a gasket between the choke and the choke housing - if you install the gasket, the choke will not ground, and it will not function.

Actually the air conditioning comes on when the defroster is on because conditioned air is dehumidified and clears the windshield better. The hot air from the heater will not crack the windshield. If that were true, there would be a thousand broken windshields where I live every day in January.

So I stand corrected and that would make total sense....and I guess the the crack in my truck windshield must have just been a freak coincidence.
