ground wire

Started by kurtstocklmeir June 21, 2017
I have a big mess.  A person took off my carburetor on my car and I can
not find the person.  The carburetor was put back on my car but there is 1
wire from the fuel cut off solenoid that is not connected to the car.  The
solenoid is part of the carburetor.  I can not find any person who knows
where the wire goes.  I think - the wire is black - it connects to ground
or negative.
If I can not find where the wire goes I can try to connect the wire to a
metal part of the car - may be this acts like a ground - may be acts like
the wire is connected to negative part of the electric circuit.  May be
this is dumb.  I do not know a lot about this like I do not know if all
grounds are the same.  I need good ideas.  Thank you for all answers.

My truck stopped running one day on the highway. I got out and not having any idea what I was expecting to find I opened the hood and looked around. After a few minutes I found a wire dangling from a part of the engine where a carburetor would go if it had a carburetor. I don't recall for sure, but I guess it was from some solenoid. Whatever it was connected to I figured it was a ground wire since it had a metal loop on the end to go under a screw. I can only assume the thing it was mounted to was somehow insulated from the main part of the engine by a paper or composite gasket on the manifold. So I found a screw I could put it under (I don't recall what happened to the original screw) and tightened it down. Sure enough the engine started and I was back to going down the road. I am pretty confident your wire is also a ground wire and should be screwed to a grounded part of the engine (which is nearly all of it unless some part is insulated by a paper gasket with no grounding wire). I seem to recall some model of Subaru had excessive corrosion in the heads and extra ground straps on the engine was the cure. Grounding can be very important. -- Rick C

I guess I should ask what is on the end of the wire. Is it a connector or a metal loop that goes under a screw or just bare wire? If it's a connector it likely needs to plug into the mating connector. Is there another wire from the solenoid for power? If not, this is likely the hot wire and should connect to whatever activates the solenoid. -- Rick C

My best guess, and this is only a guess, is that the wire from the solenoid is not a ground wire but is instead supposed to be connected to a wire that is energized when the ignition is on. If the solenoid screws directly into the metal body of the carb and there is just one wire coming from the solenoid then I am as sure as I can be without seeing the assembly or knowing the make, model, engine size, and year of the car that the wire should be connected to a positive wire that is energized when the ignition is on. So look for a wire that has a connector of the opposite sex of the connector on the end of the solenoid wire. I suspect your message was a troll but I'm a trusting type. Eric

Although the OP says the solenoid screws into the carby ( or is part of it ) and there is only 1 wire I would have to go along with it being a "hot" or positive wire. he really needs someone with a clue.

Count the number of wires from the solenoid. If it equals 2 than that wire can be ground or hot - get a manual with the wiring diagram... Go to the library and check out their Climer's or other aftermarket manuals. Check on line.... If there's only one wire it is definitely hot, and expected to actuate with the ignition circuit. This would be the "anti-dieseling" solenoid? Cuts fuel flow or shuts down the idle air to prevent the car from running when it is turned off and the engine is still very hot? Probably a hot wire that is turned on for a period of time after the ignition is switched off. Usually you find a crimped on ring if it is designed to bolt to the body or ground, and some plastic connector if it goes to the wiring harness. Color is only a clue if you have a diagram with the colors labeled.
Thank you for all answers.  I am going insane.  This carburetor has been
bad for about 1 year.  I have a 1987 Honda civic 1.5 l.  The car is about
30 years old - I can not find parts for the car and I can not find any
person who knows how to fix it.  I sent the carburetor to a factory to
rebuild the carburetor.  I got the carburetor back from the factory.  The
fuel cut off solenoid goes on the back of the carburetor.  The fuel cut
off solenoid is suppose to open when the car is turned and close when the
car is turned off - it helps to stop the carburetor from flooding when the
car turns off.  1 of my friends took off the carburetor from my car but
they left the U.S. for a certain amount of time.  They are not back.  1
more of my friends put the carburetor back on my car but they do not know
where the wire of the fuel cut off solenoid goes.  I just do not
understand what is going on - I have a degree for physics and I do not
know any thing about cars. 2 wires black color and yellow color come out
of the fuel cut off solenoid and they end with a plastic connection.  This
plastic connection goes together with a plastic connection with a wire
that ends with just 1 wire black color.  I do not understand why 2 wires
change to 1 wire.  This wire is not connected to the car but the car turns
on - it is not connected to the car because I can not find any person who
knows where it goes.  I can not understand this - how is the solenoid
getting energy.  Some fuel cut off solenoids have 1 wire and the
carburetor acts like a wire because the carburetor is connected to the
car.  I guess when this is done it is connected to a ground.  I do not
know - can this be connected to positive.  I do not know - do these
solenoids - just open when the car turns on and closes when the car turns
off or opens when the car turns on, opens more when the speed increases -
closes when the car turns off, closes more when speed decreases.  Does the
solenoid open more and close more when speed changes.  Thank you for any
answers.  To an extreme I need help.

I am from the U.S.  1 wire coming from my fuel cut off solenoid is yellow
and 1 wire is black.  I think in the U.S. a green yellow wire is a
protective ground.  My yellow wire is all yellow it does not have any
green color.  May be this yellow wire is a protective ground wire.  The
car is a 1987 Honda civic Japan may use different colors.  I do not know a
lot about protective grounds.  I guess if the yellow wire from my fuel cut
off solenoid is a protective ground it goes to a plastic connection and
stops.  I guess if the yellow wire is a protective ground the black wire
from my fuel cut off solenoid sends energy into the fuel cut off solenoid.
 My car turns on but the wires are not connected to the car - the yellow
wire and black wire go to a plastic connection - this goes to a plastic
connection that ends with 1 black wire - this wire is not connected to any
thing.  Thank you for all answers.

Wire colors do not mean anything except the particular device they are in. A car wire color is often just for the particular model they are in. Forget about how it is a protective ground. A car does not have one. They are not like the standards used for house wiring. It would be like trying to play baseball on a field layed out for football. Get a multimeter if you do not have one. You can get one for less than $ 20 that is good enough for car and home use. Check to see if either of the two wires from the solenoid are already connected internally to the case (ground) of the solenoid. One wire will show almost no resistance and the other will show a slightly higher resistance. If grounded, the low resistance is the grounded wire. If neiter wire is connected to the solenoid case you can use either wire you want. One wire (the ungrounded wire if one is grounded) goes to the connector that will have poewr on it when the switch is in the run position. Ground the other wire to the metel ( frame, motor) of the car.
